摘　　要：密肋复合墙体集承重、节能、保温、维护为一体,是一种新型抗震型墙体结构.通过8榀1/2比例密肋复合墙体模型在水平低周反复荷载作用下的试验,在考虑了高宽比、轴向压力、框格分法等因素的情况下,重点研究了密肋复合墙体的斜截面承载力计算方法.试验研究表明,密肋复合墙体具有良好的抗震性能,本文建立的密肋复合墙体斜截面抗剪承载力实用设计计算公式与试验结果吻合较好.The multi-ribbed composite wall, with the characteristics of load bearing, energy saving, heat preservation and shield wall, is a new type of wall structure with good seismic resistance performance. Based on the experiments of eight 1/2-scaled models of the multi-ribbed composite wall under low-cycle lateral loading, the influential parameters of the height-width ratio, the axial load, the form of sash, etc., were taken into account, and the calculating methods of the oblique section bearing capacity of the composite wall was studied. This study can offer reliable evidence for the design of the multi-ribbed composite wall. The results of experimental study indicate that the multi-ribbed composite wall has good seismic resistance performance, and the calculating formula of practical oblique section design of the multi-ribbed composite wall is established. The calculating results of the formula given in this paper are in accordance with experimental results.
