根据我国产业政策和建筑节能的要求,在主要城市取消和限制使用黏土砖建设多层建筑,为此提出一种新型结构即轻钢骨混凝土剪力墙结构取代砖混结构,并对该类墙体的抗震性能进行试验研究。通过5个缩尺轻钢骨混凝土剪力墙在低周反复荷载下的试验,对其承载力、破坏形态、滞回性能、耗能性、延性及其刚度退化情况等进行分析。研究结果表明,该类结构的受力性能良好,满足抗震性能要求。
According to China's industrial policy and building energy efficiency requirements, the removal and restriction of clay brick construction in major cities in the construction of multi-storey buildings, a new structure that light steel reinforced concrete shear wall structure instead of brick structure, and the wall The seismic performance of the body is tested. Through the test of five scaled lightweight steel reinforced concrete shear walls under low cyclic loading, the bearing capacity, failure mode, hysteretic behavior, energy dissipation, ductility and stiffness degradation were analyzed. The results show that this type of structure has good stress performance and meets the requirements of seismic performance.
