一、前言砌体结构大量震害表明,在地震荷载作用下,房屋纵横墙连接节点常先于主要抗侧力构件失效,而导致严重震害。连接节点失效常表现为纵横墙连接处出现垂直裂缝、外纵墙外闪等现象。连接节点的受力状态是较为复杂的。本文通过对纵横墙连接节点进行 I. Preface The massive earthquake damage of masonry structures shows that under the action of earthquake loads, the joints connecting the walls of the house often precede the failure of the main anti-lateral force components, resulting in severe earthquake damage. The failure of connection nodes is often manifested as vertical cracks at the junction of vertical and horizontal walls and external vertical wall flashing. The stress state of connecting nodes is more complicated. This article through the vertical and horizontal wall connection node
