【摘要】：混凝土密柱石膏复合墙板是一种由钢筋混凝土和石膏纤维板组成的可用于多高层建筑的新型组合墙体结构.本文对混凝土密柱石膏复合墙板在低周往复荷载作用下的滞回性能进行了数值分析,得到了复合墙板的滞回曲线和骨架曲线,讨论了剪跨比、轴压比等参数对复合墙板承载力、耗能能力及刚度退化等的影响.结果表明,混凝土密柱石膏复合墙板滞回曲线饱满,耗能能力较强,抗震性能较好,剪跨比对复合墙板滞回性能有较大影响.建立了混凝土密柱石膏复合墙板的等效带缝剪力墙简化分析模型.对等效带缝剪力墙的滞回分析表明,等效带缝剪力墙与混凝土密柱石膏复合墙板受力机理及滞回性能均较为接近,验证了采用等效带缝剪力墙进行混凝土密柱石膏复合墙板整体结构地震响应分析的适用性和可靠性.
[Abstract]:The concrete dense column gypsum composite wall board is a new type of composite wall structure which is composed of reinforced concrete and gypsum fiber board and can be used in many high-rise buildings. In this paper, the hysteretic behavior of concrete dense column gypsum composite wall slab under low cycle reciprocating load is numerically analyzed, the hysteretic curve and skeleton curve of composite wall slab are obtained, and the shear span ratio, axial compression ratio and other parameters on the bearing capacity of composite wall slab are discussed. Effects of energy dissipation capacity and stiffness degradation. The results show that the hysteretic curve of concrete composite wall board is full, the energy dissipation ability is strong, the seismic performance is better, and the shear span ratio has great influence on the hysteretic performance of composite wall board. The simplified analysis model of equivalent shear wall with joint is established. The hysteretic analysis of the equivalent shear wall with joint shows that the mechanical mechanism and hysteretic performance of the equivalent shear wall and concrete composite wall are close. The applicability and reliability of the seismic response analysis of the whole structure of concrete dense column gypsum composite wall slab with equivalent shear wall with joint are verified.
