2. Static analysis: Carry out a static analysis of the soil-structure system with the structure only subjected to gravity loading. In order to record the static reactions at the base of the structure, which are to be used in subsequent dynamic analysis of the soil-structure system subjected to earthquake excitation.
3. Transient analysis: Here, the soil-structure system which is subjected to gravity loading are analysed by time history analysis. In this method, incremental response of structure is evaluated at each time interval. Response obtained from this method is compared with conventional method (IS 11089:1984).
