The Gisborne earthquake of 20 December 2007 provided a timely reminder that it is crucial to quickly evaluate the safety of buildings and determine whether or not they are suitable for occupancy. Gisborne District Council’s actions in response to the earthquake followed the processes defined in the NZSEE Guidelines. These actions served to reassure the community that the Council was in control of the situation and to reduce anxiety amongst owners by providing rapid and authoritative decisions on the safety of their buildings and their suitability for occupation.
The primary aim of this document is to provide territorial authorities with guidance to prepare for and manage effectively a process of structural safety evaluations of damaged buildings. The focus of this document is on the rapid assessment of buildings to be carried out during the period of a state of emergency declared under the Civil Defence Emergency Management Act 2002, as may follow a major earthquake or other disaster which affects a significant number of building structures.
The scope of these Guidelines covers the Rapid Assessment of buildings to be carried out during a state of emergency declared under the Civil Defence Emergency Act 2002.
These Guidelines address disaster scenarios where there is extensive damage to buildings (residential, commercial or industrial) and infrastructure (roads, bridges, water supplies, electricity supply, telephone communications etc) over a large area, and people are likely to have been killed and injured, possibly numbering in the hundreds. The focus of this document is for the period from when the initial reconnaissance has been completed until the emergency declaration is lifted. The initial reconnaissance by emergency services and the territorial authority is necessary so that the extent of the problem is understood and areas of major concern have been identified.

Design procedures for the use of composites in strengthening of reinforced concrete structures: state-of-the-art report of the RILEM Technical Committee 234-DUC
This book analyses the current knowledge on structural behaviour of RC elements and structures strengthened with composite materials (experimental, analytical and numerical approaches for EBR and NSM), particularly in relation to the above topics, and the comparison of the predictions of the current available codes/recommendations/guidelines with selected experimental results. The book shows possible critical issues (discrepancies, lacunae, relevant parameters, test procedures, etc.) related to current code predictions or to evaluate their reliability, in order to develop more uniform methods and basic rules for design and control of FRP strengthened RC structures. General problems/critical issues are clarified on the basis of the actual experiences, detect discrepancies in existing codes, lacunae in knowledge and, concerning these identified subjects, provide proposals for improvements. The book will help to contribute to promote and consolidate a more qualified and conscious approach towards rehabilitation and strengthening existing RC structures with composites and their possible monitoring.

This book is an encyclopedia of early skyscrapers in America. Written in a chronological-order style, it presents a clear story of the progression from midrise to what we now call ‘Skyscraper’. The author, Joseph J. Korom, Jr., has researched a broad array of American skyscrapers to compile 287 buildings into this book’s 472 pages. While not every skyscraper that has been built before 1940 in America is included here, it does include a steady progression of projects from the very beginning of Tall Buildings to the mid twentieth century.
This book makes it quite clear that finance, technology, innovation, transportation, and a growing economy have all contributed to define the American skyscraper. Without the steam engine, our nineteenth century cities could not have grown. The international trade that blossomed in the late nineteenth century fueled the drive to the sky in Manhattan and Chicago. Our country’s westward expansion created large corporations with headquarters in major cities. These towers are a result of building our American financial empire.

Abstract: The Brazilian territory presents low seismicity, typical of a tectonic intra-plates region. However, at least two Brazilian regions have non-negligible seismicity: part of the Northeast Region, due to its proximity to the South Atlantic Ridge and the Brazilian Occidental Amazon, due to its proximity to the Pacific Plate border. Due this low seismicity, up to 2006 Brazil was practically the only South-American country without a seismic standard. Considering the already gathered seismological information and the theoretical studies recently performed, it has been progressively recognized that seismic effects cannot be disregarded in the structural design in Brazil. Then, in 2006, the new Brazilian Standard for the Design of Seismic Resistant Structures was concluded and issued. The seismological data, the considered probabilistic methodology and the probabilistic studies developed for defining the nominal values of horizontal accelerations in the several Brazilian regions are presented. Some aspects established in the Standard for the design of building structures are also commented.

Find 2008 (Finland + India) aims to extend already existing business relations between India and Finland, enhance awareness of the rising business opportunities that emerging new technologies have to offer and how to utilize them. The conference provides an exceptional platform for facilitating collaboration, partnerships and investments between Finland, India and third parties. This is portion of the presentation of Pekka Pulkkinen (WSP).
Once completed, the Chenab Bridge – at 1315 meters long and 359 meters high – will be the tallest Railway Arch Bridge in the world. As part of the Jammu-Udhampur-Srinagar-Baramulla Rail Line (JUSBRL), the bridge will cross over the deep gorges of the Chenab River and connect the Kashmir valley with Udhampur. The railway line itself, which has been taken up as a National Railway project will for the first time connect Kashmir to the rest of India. The bridge is designed as a massive steel arch – a first in India. To resist the challenge of hostile weather, the steel being used will withstand temperatures as low as -20C and wind speeds of 200 kmph, while being economical in cost. Forces of nature apart, the engineers also face the challenge of construction in one of the most complicated and isolated terrains, while also ensuring that the flow of the river is not disturbed.
Contents of the presentation:
1. Basic Information of the Project
2. The Bridge Site
3. Scope of Design Work
4. Description of the Bridge
5. Experiences of Cooperation between Design Consultant, Authorities and Indian Contractors
6. Conclusions

That book underscored the practice described in Strakosch with mathematical and computer analysis. Although the content of the book remains valid today, other authors have entered the field and have contributed to the theory and practice of lift traffic design and control.
In this book, I have attempted to bring together in one place a complete treatment of elevator traffic design and control. In addition to my work in the subject, the book draws on the work of other authors in the field, which I have included, commented on, extended, agreed with, or disagreed with. The interpretations are mine, as are the mistakes.
The early chapters concern well-established practice that is generally accepted. The latter chapters contain a more philosophical discussion and present controversial aspects that may require further refinement. I would like any comments and challenges to come to me in this continuing debate. Contact details are at www.liftconsulting.org.
My career has lead me through industry, research, teaching, consulting, code making and training. I have written this book for everyone involved in traffic design and traffic control of lift (US: elevator) installations. I have based it on theory arising out of practice. Lift traffic design is a practical science.

Abstract: Working closely with Foster and Partners, an astonishing column free base tower was created by supporting the entire weight of the building on only its two end cores. These heavily loaded cores allow the slender tower to efficiently resist wind loads. With a height to width ratio of 11 to 1, this 250 m tower is the ultimate in structural efficiency. To achieve this unique structure, steel trusses at intermediate mechanical levels channel loads from the floors above to the cores and serve as beams in a ‘mega-frame’ to stiffen the tower. Structural redundancy was achieved in the design by considering a failure of any one of the three truss levels. This load case was considered to ensure that total building collapse would not occur if a local failure of a truss where to occur through an accidental or premeditated event.
