Shaking table test on out-of-plane stability of infill masonry wall

Abstract

The behaviors of infill wall in earthquakes show that infill masonry walls, which are used as nonstructural elements of concrete frames, are vulnerable when they are subjected to earthquake. In order to achieve an optimal anti-seismic behavior, or even stability, two methods of connection are investigated. The shaking table tests, with 1:3 scale walls of two-storey model subjected to horizontal earthquake loads, were carried out to investigate the out-of-plane behaviors with different connections between walls and beams. The test results show that the connection methods employed between walls and beams have a significant effect on the out-of-plane stability of infill walls. The walls bound by bars with the beams perform better than those with inclined bricks without gaps.
