A seismic design of high rise buildings has assumed considerable importance in recent times. In traditional methods adopted based on fundamental mode of the structure and distribution of earthquake forces as static forces at various stories may be adequate for structures of small height subjected to earthquake of very low intensity but as the number(…)

EARTHQUAKE RESISTANT DESIGN TECHNIQUES
The conventional approach to earthquake resistant design of buildings depends upon providing the building with strength, stiffness and inelastic deformation capacity which are great enough to withstand a given level of earthquake-generated force. This is generally accomplished through the selection of an appropriate structural configuration and the careful detailing of structural members, such as beams(…)
SOURCES OF EARTHQUAKE DAMAGE
Vibration of the structure in response to ground shaking at its foundation is the concern of the structural engineer, and which is taken into account by codal provisions of the different seismic-resistant design codes. However, these codes do not include any provision due to other effects, which may even exceed that due to vibration, as(…)
EARTHQUAKE GEOTECHNICAL ENGINEERING AND ITS PRACTICES-III-EARTHQUAKE DESTRUCTION
Earthquake Destruction: Fire Earthquakes sometimes cause fire due to broken gas lines, contributing to the loss of life and economy. The destruction of lifelines and utilities make impossible for firefighters to reach fires started and make the situation worse eg. 1989 Loma Prieta 1906 San Francisco Earthquake Destruction: Tsunamis Tsunamis can be generated(…)
