Experimental study on in-plane shear strength and long team behavior of masonry walls retrofitted by prestress

Historical masonry buildings remaining in various places are rehabilitated and utilized. In order for unspecified numbers of people to use these buildings, it's necessary to secure earthquake-resistant performance. One method to reinforce such buildings while maintaining their architectural design value is reinforcement using prestressing. In this research, long-term loading tests of brick walls with introduction force were carried out by fabricating walls by reproducing joint mortar at the time of construction. This paper reports the progress measurement of the load change of the brick wall. © 2020 Architectural Institute of Japan. All rights reserved.
