【摘要】：针对村镇低层与多层建筑和再生材料应用,研发了一种模塑聚苯乙烯保温模块单排配筋再生混凝土剪力墙,该剪力墙由保温模块、再生混凝土、单排钢筋、异形柱边框和面层砂浆复合而成。进行了2个足尺剪力墙试件低周反复荷载试验,1个为模塑聚苯乙烯保温模块单排配筋再生混凝土剪力墙试件,另1个为普通单排配筋再生混凝土剪力墙试件。分析了2个试件的破坏特征、承载力、位移与延性、刚度退化及耗能性能等,提出了保温模块单排配筋剪力墙受剪承载力计算模型,其计算结果与试验符合较好。研究结果表明:与普通单排配筋再生混凝土剪力墙相比,模塑聚苯乙烯保温模块单排配筋再生混凝土剪力墙承载力明显提高,刚度退化减慢,延性好,耗能能力大幅度提高。模塑聚苯乙烯保温模块单排配筋再生混凝土剪力墙可用于村镇低层和多层抗震结构中。
[Abstract]:Aiming at the application of low-level and multi-storey buildings and recycled materials, a new type of polystyrene insulation module, reclaimed concrete shear wall with single row reinforcement, is developed. The shear wall is composed of insulation module, recycled concrete, single row steel bar, special-shaped column border and surface mortar. 2 full-scale shear wall specimens were tested under low cyclic loading. The 1 ones were molded polystyrene insulation module, single row reinforcement regenerated concrete shear wall test piece, and the other 1 ordinary single row reinforced concrete recycled concrete shear wall specimens. The failure characteristics, bearing capacity, displacement and ductility, stiffness degradation and energy dissipation of 2 specimens are analyzed. A calculation model for shear capacity of single row reinforced concrete shear walls with insulation module is put forward. The calculated results are in good agreement with the test results. The results show that compared with the single row reinforced concrete reclaimed concrete shear wall, the reinforced concrete shear wall with single row of reinforced concrete, the load capacity of recycled concrete shear wall is significantly improved, the stiffness degradation is slowed down, the ductility is good, and the energy dissipation capacity is greatly improved. The molded polystyrene thermal insulation module single row reinforced concrete shear wall can be used in the low and multi-storey earthquake resistant structures of the village.
