Abstract: The seismic performance of different building frames varies greatly according to shape. (I.e. geometric plans of the structure). By using the original earthquake forces, i.e. the various time history earthquakes, the realistic behaviour of buildings can be examined. The research is conducted on a variety of shapes, including G+05 storey L-shape, Plus-shape, and Square building frames. Two Time Histories namely El Centro (1940) and Bhuj (2001) are used to study the variation in the acceleration and displacement. The results are validated by performing study on the application software (ETABS 2018) study reveals that unsymmetrical building frames are less effective in resisting the seismic forces also out of the two Time History studied El Centro (1940) Time History is producing max acceleration and displacement in the structure.
