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 ...
Terms and Definitions Used in Earthquake Engineering
There are various terms and definitions used in earthquake engineering. Basic earthquake engineering terms are presented in the following sections. 1. Earthquake It is a transient violent movement of the Earth’s surface that follows a release of energy in the ...
Factors Influencing Earthquake Resistant Design of Structures
Structures are generally subjected to static and dynamic loads. The former is constant with time while the latter is time-varying. The majority of civil engineering structures are designed with an assumption that all the applied loads are static. The effect ...
Guidelines for Earthquake Resistant Design of Structures
An earthquake is vibration of earth surface by waves emerging from the source of disturbance in the earth by virtue of release of energy in the earth’s crust. It is essentially a sudden and transient motion or series of motions ...
