单层单跨型钢外框柱密肋复合墙体结构试验研究

Study of single story and single span multi-ribbed composite wall with steel reinforcement outside frame

通过对1/2缩尺比例的单层单跨钢骨外框柱及普通两块密肋复合墙体的低周反复加载试验,对比研究了型钢外框柱密肋复合墙体的破坏形态及承载能力、变形、延性、耗能等抗震性能。研究结果表明,两者的破坏形态基本一致,但型钢外框柱复合墙体的承载力、延性及耗能能力都明显好于普通复合墙体,说明边框柱中加入型钢后,该结构体系的抗震性能得到很大提高。

Based on experiment study of two 1/2 scale composite wall which one is general composite wall （GCW） and another is composite wall with steel reinforcement outside frame （SCW） under low frequency cyclic and reversed lateral load, it is studied to failure type and earthquake behavior about bearing capacity, deformation, ductility, energy dissipation of SCW compared with GCW. The result show that both SCW and GCW have same failure type,but the bearing capacity,deformation,ductility,energy dissipation of SCW are excellent than that of GCW, the structure system which join shape steel in outside frame column is favorable to earthquake resistance.
