ABSTRACT In this paper , effects of a critical structural parameter , beam - to - column stiffness ratio (on seismic lateral force distribution and its corresponding displacement (s) on frame members were observed . For this purpose , analysis of 12 samples of a 10 - storey frame structure having varying beam / column stiffness was carried out with the help of software facilities . To save time in the modelling and parameterization of the frame structure , a programming tool has been developed combining the functionality of VBA based excel software , Matlab and SAP2000 OAPI . With the help of this tool , parametric analysis of a significant number of frame models can automatically be generated and executed in SAP2000 in a lesser time of 139 . 0secs and at a less expense of user input . The core interest in performing the analysis is to estimate the responses of varieties of weak - column / strong - beam and strong - column / weak - beam multi - story frame subjected to seismic lateral forces by modelling the frame in its actual form [ SAP2000 ] and idealized stick model [ hand computation ] . From the analysis of the various models , comparison of SAP2000 lateral force distribution and displacement of frame models is made with that of hand calculation .
