Comparative Study on Shear Wall and Brick Wall Strengthened with Reinforced Concrete Splint

摘要

The test process and analysis of 3 walls and the expand calculation about walls are introduced in this paper. Through a series of low-cycle repeated load experiments, the paper do comparative studies on the seismic behavior of concrete shear wall and brick wall strengthened with reinforced concrete splint firstly. Because of the limitations of experiment, the study focuses on the unreinforced brick wall, the 120 mm shear wall, the brick wall strengthened with double 60 mm reinforced concrete splint and the brick wall strengthened with single 60 mm reinforced concrete splint. On the basis of the experiment, we use the finite element software to establish a rational numerical model. Through the finite element analysis, the paper expands the calculation about walls and makes up for the lack of experimental research. Based on the analysis results, we get the conclusion that the reinforced concrete splint can enhance the seismic behavior of the unreinforced brick wall. Taking no consideration of structures' integral stability, the seismic behavior of brick wall strengthened with double 60 mm reinforced concrete splint is equivalent to the 120 mm shear wall.
