摘要:
空斗墙是我国传统砌筑工艺之一,由于其抗震性能较差,遭遇地震作用时极易发生破坏。针对此类砌体结构,本文提出了基于风貌保护、采用高延性纤维增强水泥基复合材料(engineered cementitious composite,ECC)对空斗墙体进行加固的方法。通过对6片空斗墙在低周往复荷载作用下的抗震性能试验,探讨不同砌筑方式、不同加固方式对空斗墙抗震性能的影响,对比分析各试件的极限承载力、极限位移、滞回及骨架曲线、刚度退化、延性和能量耗散,研究ECC对空斗墙加固的有效性。结果表明:ECC十字条带加固技术能够有效延缓墙体裂缝开展,显著提高空斗墙的延性和耗能能力,适用于具有风貌保护要求的空斗墙房屋;ECC面层加固技术使墙体具有较好的整体性,适用于一般空斗墙房屋。
Abstract:
The cavity wall is one of the traditional masonry methods in China, because of its poor seismic performance, the cavity wall is prone to damage when it is subjected to earthquake action. For the sake of the protection of the flavorful appearance of the cavity wall, an useful method is proposed, which uses engineered cementitious composite (ECC) to strengthen the cavity wall. In the investigation, the seismic experiments of six specimens subjected to the horizontal cyclic loading combined with constant gravity loads. First,the effects of different masonry mode and different reinforcement methods on cavity wall’s seismic performance are discussed. Then,the ultimate bearing capacity, ultimate drift, hysteresis and skeleton curves, stiffness degradation, ductility and energy dissipation of different specimens are compared and analyzed. Finally, the effectiveness of ECC on the reinforcement of cavity walls is studied. The results show that ECC cross strip reinforcement can restrain the wall crack development, improve the ductility and energy dissipation of the cavity wall, which is suitable for the cavity wall buildings with the protection of original architectural style and features; ECC splint reinforcement technology can improve overall walls effectively, which is suitable for the general cavity wall buildings.
