本文对8片同一砌筑方式,不同构造加固措施的,空斗墙进行了侧向伪静力试验,通过研究在水平和垂直作用下,空斗墙初始裂缝的开展部位、裂缝形态、发展规律、开裂荷载和极限荷载,为确定经济有效的空斗墙片墙构造加固措施提供试验依据。分析结果表明,整体裂缝钢筋网加固后片墙的变形能力,延性都有所提高,有良好的抗震性能。
In this paper, eight pseudo-static test of the wall with the same masonry construction method and different structure reinforcement measures was carried out. By studying the horizontal and vertical action, the initial crack site, the fracture shape and the development law , Cracking load and ultimate load, to provide a test basis for determining the economic and effective reinforcement measures of the wall construction of the air-walls. The analysis results show that the deformation capacity and the ductility of the wall after the whole crack reinforced steel mesh are improved, and the seismic performance is good.
