Abstract

This dissertation work is carried out on the 2D RC frames to study the dynamic behaviour of MI and soft storey criteria. 2D RC frames with MI are carried out for bare frame, infill frame and soft storey having one, two, three bays with one to five storeys using SAP 2000 software. MI is modelled as equivalent diagonal strut. The modal analysis is carried out on the models, the results are compared with the available experimental results obtained from shake table tests conducted at CPRI, Bangalore and the models are validated. The Dynamic analysis involving, modal analysis to obtain natural frequencies, equivalent static analysis and response spectrum analysis to obtain base shear and displacement for all the zones (II-V) as per IS 1893(Part1):2002, time history analysis to obtain displacement are carried out. Based on the analysis results such as natural frequency, base shear, displacement are tabulated and compared and hence conclusions are drawn based on the above results.
