混凝土密柱石膏复合墙板结构性能及简化分析模型

对混凝土密柱石膏复合墙板的水平剪力传递机理进行分析，发现石膏板肋能有效地在混凝土芯柱间传递水平剪力，对复合墙板结构性能有较大影响。在此基础上，提出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，剪力墙竖缝布置以保证等效带缝剪力墙与复合墙板具有相同弹性抗侧刚度为原则确定。对混凝土密柱石膏复合墙板及等效带缝剪力墙的结构性能进行比较分析表明，混凝土密柱石膏复合墙板与带缝剪力墙受力机理相似，等效带缝剪力墙弹性及塑性阶段都能很好地反映混凝土密柱石膏复合墙板的结构性能。

Structural behavior and simplified model of plasterboard wall reinforced with in-filled RC columns

Shear transferring mechanism of the plasterboard wall reinforced with in-filled RC columns was studied. It is found that plasterboard ribs can transfer shear between in-filled RC columns effectively and have great effects on the behaviour of the composite wall. Equivalent slitted shear wall model is then presented. Slits are arranged on the equivalent shear wall to ensure it has same elastic lateral stiffness as the composite wall. Comparative analysis shows that plasterboard wall reinforced with in-filled RC columns has similar load bearing mechanism as the slitted shear wall and can be simulated by the proposed equivalent slitted shear wall for both elastic and plastic states.
