Structural Analysis is the branch which involves in the determination of behaviour of structure in order to predict the responses of different structural components due to effect of loads. Time history method gives all possible forces which are generated, and there by displacement of structure. during entire duration of ground motion at equal interval, typically 0.05to 0. A1sec. STAAD. Pro is a structural analysis design program software. To get some idea about the handling of an integral building design software like staadpro and study of seismic forces responses on building life cycle and to define the analyse behaviour of building using time history analysis. This project deals with the identification of bending and shear forces due to several load conditions. i.e., Analysis and also deals with the design of sections to increase the serviceability of the G+9)storied building. This paper gives time history analysis by using time-acceleration data as input function and then performance of the structure is evaluated with various mode shapes and time-acceleration results.
This research study investigates the change in dynamic characteristics of reinforced concrete moment-resisting frame buildings without and with fully infill walls. In addition, building models with partially infill walls have also been investigated. A set of different building models have been developed to perform the analysis as (1) bare frame (without infill walls). (2) frame with fully infill walls, (3) frame models with infill panels and soft storied located at base level, 3rd storied level, 6th storied level, and 9th storied level. The two ground excitations are applied separately in two orthogonal directions. The structural software package STAAD Pro has been used in developing the building models and performing the simulation analysis. Some selected numerical simulation results in terms of storied shear forces, lateral deflections, inter story drift ratios and overturning moments at each storied level are obtained for all the considered configurations.
