我国南方外廊式建筑的走廊,愈来愈多地采用嵌入承重横墙的伸臂梁,来支持走廊各构件而不设柱子。在伸出部分各荷载作用下,伸臂梁梁底的反力如图-1所示,受压部分的长度d,这反力也就是施加于梁底砌体的荷载(见,图-2),设梁底下h深度处有一i点,在d范 In the corridors of southern China’s corridor buildings, there is an increasing use of cantilever beams embedded in load-bearing cross walls to support the components of the corridor without pillars. Under the action of each part of the extension, the reaction force at the bottom of the jib beam is shown in Figure-1. The length d of the compression part is the load applied to the masonry at the bottom of the beam (see figure-2). , set an i point at the depth of the beam at the bottom h, in the d
