Abstract

Enormous loss to property and life loss has been witnessed during past earthquakes due to collapse of unreinforced brick masonry walls. To overcome seismic deficiency of these unreinforced masonry (URM) wall panels has led to the development of confined masonry. Confined masonry is built as a system of unreinforced masonry walls confined with tension columns and beams. The columns and beams are poured after the masonry is constructed – to maximize the interaction between masonry and the surrounding concrete members. As the concrete members are non-flexible with limited reinforcement, these systems always include the wall stiffness in the seismic load calculation as such can be potentially designed appropriately avoiding unexpected catastrophic failure. This dissertation aims to present a parametric study of typical wall panels of one. Two and three bays with and without confinement in masonry walls the different performance characteristics such as displacement, maximum and minimum stresses in wall panels etc. are studied. The cyclic load analysis is carried out on the entire mathematical 2D models using software SAP 2000. The comparison of these models is presented. Finally, the performance of masonry wall panels with openings also studied and compared.
