Abstract_Chinese: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_English:Plasterboard wall reinforced with in-filled RC columns is a new type of composite wall structure for multi-story or high-rise buildings. In this paper，the hysteretic behavior of plasterboard wall reinforced with in-filled RC columns under low cyclic loading was studied numerically. Hysteretic curves and skeleton curves were obtained and the influences of shear span ratio and axial compression ratio on bearing capacity，energy dissipation capacity and stiffness degradation were discussed. The results showed that the composite wall has plumb hysteretic curves，good energy dissipation capacity and good seismic performance. Shear span ratio has great effect on the hysteretic behavior of the composite wall. Equivalent slitted shear wall was set up as the simplified model for the composite wall. Hysteretic analysis showed that the hysteretic behavior of the equivalent slitted shear wall agreed very well with that of the plasterboard wall reinforced with in-filled RC columns，which verified the applicability and reliability of the equivalent slitted shear wall as the simplified model in seismic analysis of structures composed of plasterboard wall reinforced with in-filled RC columns.
