Dynamic response and seismic testing of CMU walls rehabilitated with composite material applied to only one side

Abstract

This project consisted of an analytical investigation and seismic shake table testing of unreinforced masonry bearing and shear walls. The analytical investigation consisted of pseudo-static and dynamic analyses of existing unreinforced concrete masonry unit (CMU) walls. The shake table testing programme consisted of uniaxial and triaxial time history testing of unreinforced masonry walls retrofitted with fibreglass composite material applied as an overlay to only one side of the walls. This paper discusses the dynamic behaviour of the analytical and physical models, the performance of the overlay composite material system, recommendations on using the system for seismic rehabilitation and retrofit of unreinforced masonry walls, and comparisons of the analytical and seismic test results.
