Seismic Loads

This book provides a practical guide to the basic essentials of earthquake engineering with a focus on seismic loading and structural design. Benefiting from the author’s extensive career in structural and earthquake engineering, dynamic analysis and lecturing, it is written from an industry perspective at a level suitable for graduate students. Fundamentals of Seismic Loading on Structures is organised into four major sections: introduction to earthquakes and related engineering problems, analysis, seismic loading, and design concepts. From a practical perspective, reviews linear and non-linear behaviour, introduces concepts of uniform hazard spectra, discusses loading provisions in design codes and examines soil-structure interaction issues, allowing the reader to quickly identify and implement information in a working environment. Discusses probabilistic methods that are widely employed in the assessment of seismic hazard, illustrating the use of Monte Carlo simulation with a number of worked examples. Summarises the latest developments in the field such as performance-based seismic engineering and advances in liquefaction research. “There are many books on earthquake engineering, but few are of direct use to the practising structural designer. This one, however, offers a new perspective, putting emphasis on the practical aspects of quantifying seismic loading, and explaining the importance of geotechnical effects during a major seismic event in readily understandable terms. The author has succeeded in marrying important seismological considerations with structural engineering practice, and this long-awaited book will find ready acceptance in the profession.” Professor Patrick J.

Earthquakes are a way of life on Earth, and, whether you live in an area that is often affected by earthquakes or not, every building, every road, every bridge, and, in fact, almost everything constructed by humans in which we walk, sleep, live, sit, or visit, has to be constructed to withstand an earthquake, by following local, regional, or national codes, laws, and regulations. Further to this, the science and engineering behind these constructions go further than what is mandated by government as a part of their practice. All construction, and, in general, all life on Earth, has some risk of seismic impacts. A comprehensive description of any seismic action may be given only on a probabilistic basis and, in general, is very bulky and quite uncertain. However, for a variety of structures or systems that meet fairly simple models of behavior during earthquakes, a general description of the seismic action is not required, for prediction of the status of such facilities or systems may be sufficient to define one or more common parameters of seismic impact. Thus, it makes sense to search for optimal parameters of influence in which optimality is understood with the greatest ease with sufficient information. This book contains a description of several models of seismic effects and examples of implementation of these models at specific sites. Using this information, scientists and engineers can design structures that are stronger, safer, and longer-lasting. It is a must-have for any scientist, engineer, or student working in or researching seismic loads and constructions with a view toward withstanding seismic activity.

Standard ASCE/SEI 7-22 provides requirements for general structural design and includes means for determining various loads and their combinations, which are suitable for inclusion in building codes and other documents.

Standard ASCE/COPRI 61-14 uses displacement-based design methods to establish guidelines for the design of piers and wharves to withstand the effects of earthquakes.

Abstract: Seismic Loads: Guide to the Seismic Load Provisions of ASCE 7-16 provides clear, authoritative explanations of the seismic design provisions contained in Minimum Design Loads and Associated Criteria for Buildings and Other Structures, ASCE/SEI 7-16. When used with the standard commentary, provided as a separate volume in ASCE 7-16, Seismic Loads assists structural engineers in applying the latest thinking in seismic design of new building structures. Authors Charney, Heausler, and Marshall present numerous detailed examples within the main 30 chapters of Seismic Loads. The examples help navigate structural engineers through the process of assessing conditions, including identifying occupancy, importance, and seismic design categories; determining the seismic requirements; and selecting a structural system. Topics include building irregularities, structural analysis, lateral system forces, load factors, drift, and P-delta effects. Major updates within the guide includeAn expanded introduction that provides a description of the history of the development of the ASCE 7 seismic provisions and how the provisions are updated on a 6-year cycle;Expanded examples of the use of Equivalent Lateral Force Analysis, Modal Response Spectrum Analysis, and Linear Response History Analysis, examples that utilize the same 8-story building;New examples covering Chapter 12 (complete seismic analysis of a simple building), Chapter 13 (nonstructural components), and Chapter 15 (nonbuilding structures); andAn expanded set of "Frequently Asked Questions," divided into topics of General Issues, Structural Design, and Structural Analysis.Seismic Loads is an essential companion to the standard ASCE/SEI 7-16 for all engineers, architects, and construction professionals who work on buildings in seismically active locations.
