A study on response spectrum and time history analysis methods for seismic analysis of prestressed concrete bridges
Due to the increase in population and development, man-made structures are also increasing rapidly, which raises the risks of hazards due to natural calamities, especially earthquakes. In this context, the importance of sufficient strength of structures to resist seismic forces has increased. The importance and necessity of seismic analysis has gained momentum in recent times, and many methods have been developed for analysis, such as response spectrum, capacity spectrum, displacement coefficient, time history, pushover analysis, etc. The suitability of response spectrum and time history method is studied in the present work and it is found that time history analysis gives more conservative results and better behavior of prestressed concrete bridges. The availability of high speed computing tools has made the computations easier; hence time history method should be preferred for the seismic analysis. Response spectrum method gives more idealistic behavior when compared to time history method.
