he Guide to Meeting the Challenges of Tall Buildings Tall buildings present unique and formidable challenges to architects and engineers because of their size, location in major urban areas, and the multiple, complex occupancies they often contain. ASHRAE Design Guide for Tall, Supertall, and Megatall Building Systems is a unique reference for owners; architects; and mechanical, structural, and electrical engineers as well as other specialized consultants involved in designing systems for these buildings. Expanded since ASHRAE's previous guide on the topic in 2004, this new design guide covers not only tall buildings (taller than 300 ft [91m]) but now also addresses supertall (taller than 984 ft [300 m]) and megatall (taller than 1968 ft [600 m]) buildings, with a broadened scope and updated content that reflects current standards and industry practices. This guide not only focuses on the efforts of designers of the HVAC systems but also addresses the importance of the design team and their collective efforts and concerns that are the critical elements in determining the ultimate solutions to the project needs of a tall building. This guide addresses design issues for tall commercial buildings, which are very often mixed use, with low-level retail, office floors, residential floors, and hotel floors. Also included are appendices with examples of stack effect and wind pressure for four representative climates, energy analysis examples, and HVAC design criteria and a systems description for a multiple-tenant office building.....
all, supertall, and megatall buildings present unique challenges because of their size, urban location and complex occupancies.
Expanded since the first edition published in 2015, ASHRAE Design Guide for Tall, Supertall and Megatall Building Systems, Second Edition has a broadened scope and updated content that reflects current standards and industry practices, including major sections on:
architectural design
indoor air quality (IAQ) and thermal comfort
vertical transportation
life safety
residential occupancy needs
intelligent buildings and controls
Each chapter refers to different parts of the building design phase, from initial concepts through specific calculations. It's ASHRAE's only reference that encompasses the entirety of tall building design.
The second edition contains all-new case studies of real-world buildings and supplemental files throughout, plus new information on stack effect, controls, Smart Grid, and high-rise residential.
It's an ideal companion text for owners, architects, engineers, and other specialized consultants involved in designing systems for these formidable projects.

The 4th International Conference on Performance-based Design in Earthquake Geotechnical Engineering (PBD-IV) is held in Beijing, China. The PBD-IV Conference is organized under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering - Technical Committee TC203 on Earthquake Geotechnical Engineering and Associated Problems (ISSMGE-TC203). The PBD-I, PBD-II, and PBD-III events in Japan (2009), Italy (2012), and Canada (2017) respectively, were highly successful events for the international earthquake geotechnical engineering community. The PBD events have been excellent companions to the International Conference on Earthquake Geotechnical Engineering (ICEGE) series that TC203 has held in Japan (1995), Portugal (1999), USA (2004), Greece (2007), Chile (2011), New Zealand (2015), and Italy (2019). The goal of PBD-IV is to provide an open forum for delegates to interact with their international colleagues and advance performance-based design research and practices for earthquake geotechnical engineering.

This book critically assesses Christchurch, New Zealand as an evolving post-earthquake city. It examines the impact of the 2010–13 Canterbury earthquake sequence, employing a chronological structure to consider 'damage and displacement', 'recovery and renewal' and 'the city in transition'.
It offers a framework for understanding the multiple experiences and realities of post-earthquake recovery. It details how the rebuilding of the city has occurred and examines what has arisen in the context of an unprecedented opportunity to refashion land uses and social experience from the ground up. A recurring tension is observed between the desire and tendency of some to reproduce previous urban orthodoxies and the experimental efforts of others to fashion new cultures of progressive place-making and attention to the more-than-human city. The book offers several lessons for understanding disaster recovery in cities. It illuminates the opportunities disasters create for both the reassertion of the familiar and the emergence of the new; highlights the divergence of lived experience during recovery; and considers the extent to which a post-disaster city is prepared for likely climate futures.
The book will be valuable reading for critical disaster researchers as well as geographers, sociologists, urban planners and policy makers interested in disaster recovery.

The monograph entitled “Dynamics of Structure and Foundation -– A Unified
Approach” consists of two volumes. While in Volume 1 we dealt with background theories and formulations that constitute the above subject, this second volume deals with application of these theories to various aspects of civil engineering problems constituting topics related to dynamic soil-structure interaction, machine foundation and
earthquake engineering. If we have managed to stir the wrath of the professionals in Volume 1 with mazes of tensors, differential and integral equations, it is our strong conviction that in this
present volume we will be able to considerably appease this fraternity for it constitutes of a number of applications that are innovative, easy to apply and solutions to many practical problems that puts an engineer into considerable difficulty and uncertainties in a design office. We start Volume 2 with the topic of Dynamic Soil Structure Interaction (DSSI). We
believe this topic would play a key role in future and more so with the distinct possibility of construction of Nuclear power plants (especially in India) globally. A clear concept on this topic would surely be essential for designing such plants. Though we have dealt this topic only in terms of fundamental concepts, yet we feel that we have given sufficient details to eradicate the misnomer from which many engineers suffer that “DSSI is nothing but adding some springs to the boundary of a structure and then
doing the analysis through a computer”.The geotechnical aspects that play an extremely important role in selecting the soilspring value, (that are highly influenced by the strain range) have been dealt in quite
detail. We hope that this section will do away with some of the major blunders that we make in DSSI analysis, and appreciate how the results thus obtained become unrealistic and questionable. We sincerely hope that engineers performing DSSI analysis, would start paying sufficient attention to some of the key engineering parameters as furnished in the soil report – that are being habitually ignored in design offices.
Second chapter consists of design and analysis of machine foundations (both block and frame type). In our collective experience as a consultant and academician we have seen significant confusion on this topic as to who is responsible for this hapless orphan, structural or geotechnical engineers? While people from classical soil mechanics disowns it, as it involves the evaluation of eigen-values and vectors that are far away their traditional failure theories of foundation, structural engineers on the other hand
are equally reluctant to shoulder the guardianship for their inherent apathy towards ‘what lies beneath the machine foundation’. As such, a design involving machine foundation throws the most challenging and interesting task in the domain of civil engineering that requires multi-discipline knowledge and should be equally interesting to an engineer having structural or geotechnical background. The matrix analysis
concept that we have introduced herein is quite easy to follow and we hope wouldB bridge the gap that is still prevalent in academics and practice alike. We would be looking forward to have some feedback from hardened professionals who are working in this area, as to how they feel about our representation which we believe is quite novel and has tried to answer a number of problems that often become burning issues on which they have spent significant time on clarifying either to their Clients or Project Management Consultants.
The last chapter of this volume deals with the most fearful force Mother Nature has created – “Earthquake”. Earthquake engineering as a topic is so vast, complex and diverse (and ever changing) that we concede that it did give us some uncomfortable moments as to what should justifiably constitute this chapter? Majority of the books that address this topic are far too focused on buildings and there are hardly any book
around, that has addressed other specialized structures like chimneys, dams, retaining walls, water tanks etc (except some very specialized literature). It should be realized that some of these structures are expensive, important and cannot be ignored while building an earthquake resistant infrastructure.
Buildings, we concede are the biggest casualties during an earthquake and are directly related to human life but damages to other structures as mentioned above can also create havoc especially in the post earthquake relief scenario. The major focus being still thrust on buildings, we were also quite surprised to find that there is still much room for improvement in many of these structures, where technologies which are as old as 60 years are still in use (for instance earthquake response of retaining walls). We tried to improve upon many of them and believe that we have brought about
a number of innovative solutions that can be adapted in a design office environment and can also be used as a basis for further research.
While presenting the topic no demarcation is made between geotechnical and structural earthquake engineering. For, as a seismic specialist our job is to minimize the destruction of property and save human lives. Thus doing a structural design we can perform the most sophisticated analysis and provide the most expensive detailing and our building still fails due to liquefaction killing people__“no medals for doing an excellent structural design!”, so if you do something do it in totality and not in isolation and this has been our major endeavour- that we have tried to communicate to you through this book.

STOCHASTIC STRUCTURAL DYNAMICS APPLICATION OF FINITE ELEMENT METHODS
Author(s)/Editor(s): Cho W. S. To Professor of Mechanical Engineering University of Nebraska-Lincoln, US | Size: 12.84 MB| Format:PDF| Publisher: WILLY
The parallel developments of the finite element methods (FEM) in the
1950's [1, 2] and the engineering applications of the stochastic processes in the 1940's [3, 4] provided a combined numerical analysis tool for the studies of dynamics of structures and structural systems under random loadings. There are books on statistical dynamics of structures [5, 6] and books on structural dynamics with chapter(s) dealing with random response analysis [7, 8]. In addition, there are various monographs and lecture notes on the subject. However, a systematic treatment of the stochastic structural dynamics applying the FEM seems to be lacking. The present book is believed to be the first relatively in-depth and systematic treatment of the subject that applies the FEM to the field of stochastic structural dynamics.
Before the introduction to the concept and theory of stochastic quantities
and their applications with the FEM in subsequent chapters, the two FEM
employed in the investigations presented in the present book are outlined in this chapter. Specifically, Section 1.1 is concerned with the derivation of the
temporally stochastic element equation of motion applying the displacement
formulation. The consistent element stiffness and mass matrices of two beam elements, each having two nodes are derived. One beam element is uniform and the other is tapered. The corresponding temporally and spatially stochastic element equation of motion is derived in Section 1.2. The element equations of motion based on the mixed formulation are introduced in Section 1.3. Consistent element matrices for a beam of uniform cross-sectional area are obtained. This beam element has two nodes, each of which has two degrees-of-freedom (dof).
This beam element is applied to show that stiffness matrices derived from the displacement and mixed formulations are identical. The incremental variational principle and element matrices based on the mixed formulation for nonlinear structures are presented in Section 1.4. Section 1.5 deals with constitutive relations and updating of configurations and stresses. Closing remarks for this chapter are provided in Section 1.6

Dynamics of Structure and Foundation – A Unified Approach 1. Fundamentals
Author(s)/Editor(s): Indrajit Chowdhury Petrofac International Ltd Sharjah, United Arab Emirates Shambhu P. Dasgupta Department of Civil Engineering Indian Institute of Technology Kharagpur, Indi | Size: 7.85 MB| Format:PDF| Publisher: CRC PRESS
1.1 WHY THIS BOOK
It is said that authorship of any kind is a tremendous boost to one’s ego. Readers, who would care to go through these pages, can be rest assured that this book has not been written to gratify one’s ego trip.
Reason for its birth has been our deep-rooted concern on the way profession of engineering and especially civil engineering is going – in terms of teaching and practice.
Civil Engineering is perhaps the oldest profession amongst the realms of technology, which has been practiced by human being from the early dawn of civilization. It is also indeed a fact that umpteen numbers of books have been written addressing various topics on Civil and Structural engineering from the time of Galileo (1594) till date. So what made us write this book when many of the things mentioned herein may or may not be available in other literature?
The reason for its birth can be attributed as follows:Civil engineering community in India, in spite of making a lot of progress, very few
authors have addressed the topics that we have tried to cover under one platform.
Topics related to structural and soil dynamics that are taught in the universities or referred to in design offices are still dependent on very limited number of books1, or code of practices (often outdated) or research papers not readily available to an average student/engineer.
Finally, in last two decades we have seen a very peculiar trend and that which has affected the profession globally, and could have a long lasting influence on it.
If we look around the world in terms of books published in civil engineering in the last two decades (1980–2000) it will be observed that unlike the period 1960–70 almost all books have been authored by academicians where practicing engineers rarely contributed! Whatever could be the reason for this apathy from engineers in the industry the point remains that students coming out of engineering institutes, unlike 30 years ago
are being exposed minimally to practice as prevalent in industry.
And this we believe is creating a serious gap in engineering education. Till such times practicing engineers are encouraged like in developed countries to participate in teaching we are fearful that engineering especially civil engineering will metamorphose into more an advance course in mathematical physics rather than a scientific art where theory is honed by intuitive practices and field realties.
Engineering is not only a maze of differential equations, tensors, matrix algebra, or developing software program. It is much beyond these, where all these mathematical techniques are mere tools in the hands of a capable engineer who can intuitively visualize the behavior of the structure and foundation he is going to design and check his
intuitive deduction based on the above tools in hands and this makes it essential to synthesize theory and practice that becomes the hallmark of a complete engineer
