Extensive amounts of operational data are generated over time by the health monitoring system of a structure’s management system, yet there are few analysis algorithms which can tell the exact working state of the structure on-line. Good maintenance engineers need to know the exact location and state of the structural components after an earthquake or some attack or accident involving the structure, possibly within a matter of hours, and the client also demands a rapid diagnosis of the structure before making decisions on any necessary remedial work.
This book is devoted to the condition assessment of a structure under operational loading, with most of the illustrations related to a bridge deck under a group of moving vehicular loads. More generally, a wide variety of excitation forces can be exerted on a structure, from earthquake excitation, wind loading, vehicular loading or ambient excitation at the supports. Different algorithms may be used to enable real time identification with deterministic results on the state of the structure. This book also covers a group of damage-detection-oriented-models developed by the author, including a new decomposition of the system matrices of the beam element and plate element. Methods for extending the deterministic condition assessment to provide statistical information are also included. The methods and algorithms described can be implemented for the on-line condition assessment of a structure through model updating of the structure during the course of extreme loading such as an earthquake, or when under normal ambient excitation or operation excitation. Different sample structures are described and analysed, supplemented with major references.
This leading-edge work will be especially useful for researchers and graduate students, and it is also heavily rooted in advanced engineering practice.

Significant Changes to the Seismic Load Provisions of ASCE 7-10 : An Illustrated Guide
Author: S. K. Ghosh, Ph.D.; Susan Dowty, P.E.; and Prabuddha Dasgupta, Ph.D., P.E. | Size: 19 MB | Format:PDF | Quality:Original preprint | Publisher: S. K. Ghosh Associates Inc | Year: 2011 | pages: 204
Significant Changes to Seismic Load Provisions of ASCE 7-10: An Illustrated Guide focuses on the revisions to the seismic load requirements set forth in the latest edition of the Standard for minimum design loads. Mirroring the organization of the seismic chapters in ASCE 7-10, this handy reference briefly summarizes each change to the seismic provisions that might affect actual practice or enforcement and immediately follows up with the precise wording of the change. The impact of each update is explained in clear, straightforward language accompanied by diagrams, examples, and color photographs and illustrations to enrich the reader's understanding.
Significant Changes to the Seismic Load Provisions of ASCE 7-10: An Illustrated Guide translates the changes to the seismic provisions of ASCE Standard 7-10 into a form readily accessible by structural engineers, architects, contractors, building officials and inspectors, and allied professionals.

The definitive design and construction industry source for building with wood—now in a thoroughly updated Sixth Edition
Since its first publication in 1966, Timber Construction Manual has become the essential design and construction industry resource for building with structural glued laminated timber. Timber Construction Manual, Sixth Edition provides architects, engineers, contractors, educators, and related professionals with up-to-date information on engineered timber construction, including the latest codes, construction methods, and authoritative design recommendations. Content has been reorganized to flow easily from information on wood properties and applications to specific design considerations.
Based on the most reliable technical data available, this edition has been thoroughly revised to encompass:
> A thorough update of all recommended design criteria for timber structural members, systems, and connections
> An expanded collection of real-world design examples supported with detailed schematic drawings
> New material on the role of glulam in sustainable building practices
> The latest design and construction codes, including the 2012 National Design Specification for Wood Construction, AITC 117-2010, and examples featuring ASCE 7-10 and IBC 2009
> More cross-referencing to other available AITC standards on the AITC website

Predicting water runoff in ungauged water catchment areas is vital to practical applications such as the design of drainage infrastructure and flooding defences, runoff forecasting, and for catchment management tasks such as water allocation and climate impact analysis. This important new book synthesises decades of international research, forming a holistic approach to catchment hydrology and providing a one-stop resource for hydrologists in both developed and developing countries. Topics include data for runoff regionalisation, the prediction of runoff hydrographs, flow duration curves, flow paths and residence times, annual and seasonal runoff, and floods. Illustrated with many case studies and including a final chapter on recommendations for researchers and practitioners, this book is written by expert authors involved in the prestigious IAHS PUB initiative. It is a key resource for academic researchers and professionals in the fields of hydrology, hydrogeology, ecology, geography, soil science, and environmental and civil engineering.
> A full colour synthesis of decades' worth of world-wide research by expert practising hydrologists, forming the first complete compendium of hydrologic prediction methods
> Analyses Newtonian (bottom-up) and Darwinian (top-down) approaches to the complex environmental systems of water catchments
> Emphasises comparative hydrology, with a range of diverse methods and models, providing a sound framework for predictive capability in ungauged catchments

This publication has been developed to provide guidance as to how the direct displacement-based design methodology can be codified. It is intended for insertion within the seismic requirements of a code, establishing how design forces can be obtained using a Direct Displacement-Based Design (DDBD) approach. The document has currently been drafted with reference to several clauses of Eurocode 8. This document is presented in a traditional “Code + Commentary” format, on a split two-column page. The commentary aims to generally clarify the code requirements and indicate references where the background and further discussion on the requirements can be found
