预应力装配混凝土复合墙板抗震性能试验研究

Experimental analysis on seismic behavior of prefabricated concrete composite walls

结合砌体结构的发展现状和住宅产业化的发展趋势,提出一种"预应力装配混凝土复合墙板",以期望在中小城镇低层建筑民用房屋中发展一种新的结构形式来对砌体结构进行补充。为了考察该复合墙板的抗震性能,对2块不同预应力度的试件进行了拟静力试验。得到了相应试件的抗震性能指标,显示该墙板具有较好的承载能力和变形性能,分析认为所提出的墙板可以达到8度区低层民用房屋的应用要求,可以作为砌体承重墙的一种替代形式,并且对该墙板相关构造提出了改进建议。

Based on the present situation of masonry structure and the development of housing industrialization,We proposed an invonative unbonded post-tensioned precast concrete composite wall to develop a new structure form in the low-rise civil construction.We studied two specimens with various levels of pre-stressing were studied experimentally by the quasi-static test system to investigate the seismic behavior of the composite wall and obtained the seismic behavior indexes of corresponding specimens.The results show that the walls have better bearing capacity and good ductility.They could meet the application requirements of the low-rise building in eight-intensity area and be used as an alternative of masonry loadbearing wall structure.We also presented some suggestions about the structure forms of the compostie wall.
