A Study of Effect of Earthquake Ground Motion on Analysis of Structures | Original Article

ABSTRACT:

The effect of the earthquake on a building depends not only on the peak value of ground acceleration, but also on the size and shape of the building, the arrangement of structural elements, and the presence of mass and stiffness irregularities. Dynamic analysis needs to be performed for knowing the performance of the structure under earthquake loading. The dynamic analysis can be linear or nonlinear. Linear analysis is performed using response spectrum method. Non-linear analysis can be performed using time history analysis. There is advancement in computing techniques with the arrival of more powerful computers. Advanced computer programmes and applications are developed for seismic analysis of the structures. In present study a programme is written in MathCADsoftware and the output is validated for with professional software STAAD.Pro for different configurations of the structures.The modal response is compared for evaluating natural frequency, fundamental time period, modal frequency, mode shape coefficients.
