Abstract:

The effect of masonry infill panel on the response of RC frame subjected to seismic action is widely recognized and has been subject of numerous experimental investigations, while several attempts to model it analytically have been reported. In analytically analysis infill walls are modelled as equivalent static approach there are various formulae derived by research scholars and scientist for width of modelling. Infill behaves like compression between column and beam and compression forces are transferred from one node to another. In this study the effect of masonry walls on high rise building is studied. Static analysis on high rise building with different arrangement is carried out. For the analysis G+9 R.C.C framed building is modelled. The width is calculated by using equivalent static method. Various cases of analysis are taken. All analysis is carried out by software STAAD-PRO. Axial Force, Shear Force, Storey drift, Nodal displacement, bending moment is calculated and compared for all models. The results show that infill walls reduce displacement, time period and increase base shear. So it is essential to consider the effect of masonry infill for the seismic evaluation of moment resisting reinforced concrete frame.
