Structural designing requires structural analysis and earthquake or seismic analysis of any structure prior to construction. Earthquake or seismic analysis is the calculation of the response of a structure subjected to earthquake excitation. Various seismic data are necessary to carry out the seismic analysis of the structures in this study the seismic response of the structures is investigated under earthquake excitation expressed in the form of member forces, joint displacement, support reaction and story drift. The response is investigated for g+7 building structures by using STAAD PRO designing software. We observed the response reduction of cases ordinary moment resisting frame. In this case, we have taken earthquake zone 2, response factor 3 for ordinary moment resisting frame and importance factor 1. Initially, we started with the designing of simple 2-dimensional frames and manually checked the accuracy of the software with our results. Then according to the specified criteria assigned it analyses the structure and designs the members with reinforcement details for G+7 residential building RCC frames. The minimum requirements pertaining(Be appropriate) to the structural safety of buildings are being covered by way of laying down minimum design loads which have to be assumed for dead loads, imposed loads, and other external loads. In order to be able to prevent or to minimize the occurrence of cracks, it is necessary to understand basic causes of cracking and to have knowledge about certain properties of building materials, the specification for mortar and concrete, the Architectural design of building, structural design, foundation design, construction practices & techniques and environments.
