2. Motivation
● Seismic analysis allows us to visualize the response of a bridge
during earthquake.
● It is a tool for the estimation of structural response in the process of
designing earthquake resistant structures.
● It enables us to obtain the additional forces or deformations that
would generate because of an earthquake.
● Knowledge of bridge behaviour for different types of loading.
● Evaluation of seismic vulnerability through the failure probability
quantification.

4. Introduction
● A Bridge is a structure which is built over some physical obstacle such as
a body of water, valley or road.
● It is built to be strong enough to safely support its own weight as well as
the weight of anything that should pass over it.
● Seismic design is a vital process of structural analysis while designing a
building, which is subjected to Earthquake ground motions.
● Bridges are important structures in modern highway and railway
transportation systems, and generally serving as “lifelines” in the social
infrastructure systems.
● Seismic analysis is needed to investigate the response of a structure to
earthquakes & design the structures accordingly.

5. Applications & Advantages
• Examine the effects of different soil conditions in different
earthquake zones for foot over bridge.
• It gives most structurally efficient and economic foot over bridge
superstructure according to earthquake zone and suitable soil
condition.
• Skills of modelling bridges in different ways as per IRC standards.
• Evaluate effects of asynchronous ground motions.
• Assess magnitude and distribution of forces developed under
seismic loading.
• Seismic analysis provide a structural system that will not collapse.
• it prevent loss of life and will limit economic loss during an
earthquake.
