|Abstract:||The most building codes state that the lateral earthquake force at each story level of an asymmetric-plan building should be applied eccentrically from their centres of rigidity . So to implement such procedures, it is necessary to determine the locations of centres of rigidity of each floor level in case of asymmetric-plan building. The location of centres of rigidity of an asymmetric-plan building in itself is a very difficult and time consuming process. In this dissertation, an evaluation test of the approach given by Chopra and Goel for lateral force analysis of an asymmetric-plan building without locating the centre of rigidity of its floors is given. The shear forces in the asymmetric-plan building are determined with the help of.~taad-III package. In one approach,the lateral forces and torques are applied on the centre of rigidity of the floor and in the second approach,the lateral forces and torques are applied at the centre of mass of the floor. The evaluation test of approach given by Chopra and Goel presented in this thesis dispels the long held view that locations of centres of rigidity must be determined for the implementation of the code procedure, and therefore, it removes a major difficulty in the analysis of buildings.|
