Infilled Steel Frames Subjected to Seismic Loads
The performance of the structure during an event of earthquake depends critically on its shape, size, and geometry, along with the method of earthquake forces are transmitted to the ground. It is necessary to analyse and strengthen them based on evaluation criteria before the earthquake occurs. In the present paper, an attempt is made to study the difference in structural behaviour of A three-dimensional (3D) 4 × 4 bays of 10 storey moment resisting steel frame structural model when provided with different types of infill materials such as burnt brick masonry and precast panels in the event of an earthquake. The detailed investigations are carried out as per IS 1893 (Part–1):2016, considering primary loads (dead, live, and seismic loads) and their combinations with appropriate load factor. The models analysed consist of one moment resisting steel frame (bare frame), steel frame provided with masonry infills, and steel frame with precast panels. The above-mentioned models are analysed and designed for the static analysis using pushover analysis using SAP2000 software to obtain the steel beam and column sections for the structure by multiple iterations after analysing these finalised models results obtained from the static analysis are thoroughly shows that base shear was found reduced for all the three models and Burnt brick masonry model shows higher displacement at performance level compared to other models. The overall performance of the structure was found safe and all the three structural models are within safer limits.
