Study on Effect of Infill Walls in Multistorey Irregular R.C. Framed Structure with Shear Wall

This paper is concerned with study of effect of infill walls on regular and irregular R.C framed structure with shear wall. The objective of the project work is to carry out Equivalent static analysis and Time History analysis of vertically irregular R.C. building frames. IS 456 : 2000 and IS 1893 : 2002 codes are used. Comparison of results of all the models for different soil types and different earthquake zones are done. Structure is analysed using sap 2000 software. Model analysis is carried for three types of soil, for all four models in each type of soil and results for periods and frequency are obtained. Time – History analysis is done for all the models and results are obtained and compared. Graphs are obtained for displacement along X and Y direction. Comparison of shear force results of four models in each of four earthquake zones shows that infill walls increases shear forces at base for all earthquake zones. Storey displacement comparision shows that infill wall decreases the displacement of structure in all earthquake zones.
