Earthquakes can cause local soil failure, surface rupture, structural damage and human death. The most important seismic impact on buildings and their structural components is due to seismic waves propagating out ward in all directions from the earthquake focus. These different types of waves can cause significant ground movement up to hundreds of miles from the source. Its motion depends on the intensity, sequence, duration and frequency content of the ground motion due to the earthquake.
For design purposes, seismic motion is described by the history of the assumed ground acceleration and is generally expressed in terms of the response spectrum derived from that history. When the recording is not available or insufficient, a smoothed response spectrum has been devised for design purposes to characterize the ground motion. As a rule, the designer describes the seismic motion as follows of 2 vertical horizontal components and vertical components for the entire base of the structure.
This book provides a general introduction to the topic of three-dimensional analysis and design of buildings for resistance to the effects of earthquakes. It is intended for general readers, especially those of interest in the design and construction of buildings under serve reloading.
The majority of seismic design includes building structures that have a major role in preventing serious damage and structural collapse. Many of the materials in this book examine building structures, specifically, their resistance to vertical and lateral forces or combinations.
However, the discovery of the vertical component of the large acceleration of the magnitude in the recent Kobe earthquake has changed the original concept of “lateral force only”. The book advocates the contribution of this disastrous element in global analytical research.
When an earthquake occurs, the entire building and its contents shake. A complete analysis of the design layout and type of earthquake should therefore include considerations for the construction of a complete building, the content of the building and the occupants of the building.
The work of design for earthquake impact is based on a steady stream of accumulated knowledge gained from research, research, new technologies and forensic investigations of earthquake damaged buildings.
Because of this cumulative flow of knowledge, practices, regulatory codes and professional standards are continually being upgraded. Therefore, books on this subject should be regularly updated. We have a lot to offer.
