Behaviour of Irregular Concrete Buildings under Seismic Forces
Abstract: The study of irregularities in a building is a fundamental parameter controlling the seismic response of buildings. From the past history of earthquakes, it is evident that the use of improper structural configurationswith plan irregularities and soft storeys has decisive effects on the seismic performance of buildings. The buildings with abrupt changes in storey stiffness have uneven lateral force distribution along the height, whichis likely to locally induce stress concentration. …
