RC框架-格构混凝土填充墙结构振动台试验研究
|
摘要
水泥聚苯模壳格构混凝土填充墙体是一种集保温、阻燃、经济于一体的新型墙体,本文对一栋1:1比例单层足尺钢筋混凝土框架-水泥聚苯模壳格构混凝土填充墙模型进行了模拟地震振动台试验,研究结果表明,这种结构具有良好的抗震性能,高宽比大于2的纵墙平面内呈弯剪破坏,高宽比为1的横墙则为剪切破坏。按模型设计的不同连接方式,都能保证填充墙与框架的协同工作。
Cement polystyrene lattice shell mould concrete fill wall panel consisted of cement polystyrene formwork concrete lattice is a new type of bearing walls having both of load-bearing capacity,insulation and fire resistance.The paper describes a simulated earthquake shaking table test on a full scaled single story building structure of reinforced concrete frame-cement polystyrene mold shells filled with concrete walls lattices. The test shows that this structure has a good seismic performance,for longitudinal walls with high aspect ratio greater than two in wall plane bending-shear failure was observed and for transversal walls with high aspect ratio of unit shear failure was observed. In addition,a good collaboration between the frame and infilled walls can be achieved by all connections implemented in the building structural model design.
