This thesis focuses on the seismic capacity of RC framed building structure and the effects of the brick masonry infill walls on the seismic capacity evaluation. Bangladesh is adopting the JBDPA (Japan Building Disaster Prevention Association) with required modifications.
This thesis will represent a comparative study of an existing model building in Bangladesh by JBDPA Standard and the non-linear pushover analysis procedure described in ATC-40/FEMA 273/356/440 EL. Masonry infill has a vital role in seismic performance of RC frame buildings. JBDPA Standard does not consider the effects of masonry infill in the assessment procedure.
In the non-linear frame analysis, infill was considered by using equivalent diagonal strut method. The equivalent strut width was evaluated by several state-of-the-art methods.
A calibration of the non-linear frame analysis was performed by using the experimental data of four RC frame specimens with and without infill which were tested in Bangladesh.
The non-linear frame analysis on the sample RC frames of an old building and the same frame designed by current code was evaluated. Parameters were the location and quantity of infill masonry walls. Being a very brittle non-structural element, the infill masonry wall affect the seismic behavior and influences the seismic capacity, displacement, structural time period and also introduce soft story effect for open ground floor buildings.
