Abstract

Shear wall known as high performance structure to resists seismic load. It has important that shear wall can be applied to masonry building as bearing wall in simple way, high performance, and low-cost. Therefore, this research wants to develop a simple way as well as simple shear walls that are connected by column as stiffer couple to strength the masonry wall. The aim of this research is to investigate compressive strength of couple simple shear wall compared to analytical compressive strength and also compressive strength of previous research. There were two couples of simple shear wall built on site, one was strengthening of the outer side of house wall and the other one was strengthening of the inner of masonry wall border edging, which are connected with column that placed at the edge and also in the corner. Each wall has dimension of 1 x 1 x 0.2 m while the column dimension was 0.20 x 0.20 m. Field application in this research followed by Rebound Hammer Test. The field result then compared of theoretical compressive strength and compressive strength of previous research. It is proven that couple simple shear wall easy to build and low-cost as well as simple design, ease for construction, and effectively strengthens the wall. The couple simple shear wall compressive strength was higher compared to compressive strength of masonry walls without strengthening and the theoretical compressive strength. © International Research Publication House.
