摘　　要：进行了一榀不等跨框支密肋壁板结构连续墙梁模型的伪静力试验,介绍了模型试件的破坏过程。根据试验结果,对这种形式墙梁的破坏形态、承载力、刚度、变形特性及滞回性能等抗震性能进行了分析研究,并与框支砖砌体墙梁进行了一定的对比分析。研究表明,框支密肋壁板结构墙梁具有良好的抗震性能。In this paper, the pseudo-static model experiment of a frame-supported multi-ribbed continuous wall beam with unequal spans is presented. The failure process of the model is introduced. Based on the experimental results, the seismic performance of the wall beam, such as failure mode, bearing capacity, rigidity, deformation features and hysteretic characteristic, is analyzed and studied. At the same time, the seismic performance of the wall beam is contrasted with that of frame-supported frame-supported multi-fibbed composite wall beam has masonry wall beam. The studied results are shown that the good seismic performance.
