在水平低周反复荷载作用下,通过对6片节能砌块隐形密框墙板1/2模型的试验,研究标准墙体的主要破坏过程,并对钢筋应变进行分析.结果表明,墙体的破坏过程大体可分为弹性阶段、弹塑性阶段、破坏阶段,分别对应不同的力学模型.墙体中,肋梁、肋柱与内部填充砌块、墙板与外框具有良好的共同工作特性.此外,距边第二内肋柱在弹性阶段分担部分整体弯矩,在弹塑性阶段分担部分水平荷载;内肋柱分担部分水平荷载;肋梁主要承担水平荷载;边肋柱主要承担墙体的整体弯矩.
Under the effect of horizontal low cyclic loading, the main failure process of the standard wall was studied by testing the 1/2 model of the six stealth dense-frame wall panels of the energy-saving block. The steel strain was analyzed. The results showed that the wall The failure process can be roughly divided into elastic stage, elasto-plastic stage, and destructive stage, which correspond to different mechanical models. In the wall, rib beams, ribs and internal filled blocks, wall plates and frames have good common operating characteristics. In addition, the second internal ribs on the distance from the side share the overall bending moment in the elastic stage, sharing some of the horizontal load in the elastoplastic stage; the internal ribs share part of the horizontal load; the ribs mainly bear the horizontal load; the side ribs mainly bear the wall Overall bending moment.
