Abstract:
From the past earthquakes, it has been observed that if the bridges are not
properly analyzed, designed and constructed with required quality, it may lead to great
destruction and loss of human lives. It has been proven that many of the bridges are
fully or partially damaged due to earthquakes. This work is divided into two parts; the
first one presents the seismic design of structures using response spectrum method and
linear time history method and the second part is about the classical non-linear time
history analysis. Seismic analysis of the structure is carried out for determination of
seismic responses by time history analysis which is one of the important techniques for
structural seismic analysis especially when the evaluated structural response is nonlinear
in nature. As time history is a realistic method, used for seismic analysis, it
provides a better check to the safety of the structures as compared to equivalent static
analysis and response spectrum methods. IS code compatible time histories have been
taken for analysis and design of the substructure of the bridge.
