Structural performance of reinforced cement stabilized earth masonry (CSEM) subjected by In-Plane lateral loads

Abstract

Various techniques have been developed to reinforce masonry structures and each of these methods has their pros and cons. The objective of the authors was to develop a method which is best suited for conditions prevailing in Sri Lanka incorporating structural performance, cost and ease of construction. In this study Cement Stabilized Soil Block masonry was selected to be tested for seismic performance due to its interlocking nature and ease of installation of vertical reinforcement. A sample house of CSEM was analysed for seismic performance using a computer model and the critical areas in the structure were identified. A wall with an opening was identified as critical location; it was reinforced and tested under in-plane lateral loads. Final Comparisons were done to check performances
