摘要

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。
Based on pseudo-static test of cavity wall with different constructional measures,which have the same masonry methods but different reinforcements,the essay does some research on the position of the initial crack,the fracture morphology,development law,the initial load,ultimate load.In order to provide test basis for the determination of economical and effective construction measures for cavity wall.The results show that covering the overall wall with the steel meshes can improve the deformation capacity of the wall,improve the wall's ability to resist earthquake.
