摘　　要：通过1/4缩尺钢框架-钢板剪力墙混合结构模型模拟地震振动台试验和理论计算分析,研究了某新型装配整体式楼盖和相应等效现浇楼盖对水平地震力在不同抗侧力构件之间分配的影响及其刚度对比情况。研究和分析表明:新型连接装配楼盖较相应等效现浇楼盖面内刚度略低,二者对水平地震作用的传递能力接近,均可保证模型结构中不同抗侧力构件之间的协同工作。另基于非刚性楼盖的"串并联质点系"矩阵位移法对比分析表明,本文所研究的新型装配楼盖的水平抗推刚度与设置50mm厚后浇面层的普通装配式楼盖的水平抗推刚度接近。Through simulating the earthquake shaking table test and the theoretical calculation analysis of a 1/4 reduced scale steel frame-steel plate shear wall mixed structure model, the influence of a new assembled monolithic floor and corresponding equivalent cast-in-place floor on the horizontal seismic force distribution between different components resisting lateral forces, and the contrast of their stiffnesses are studied. The research and analysis shows that the in-plane stiffness of the new assembled monolithic floor is slightly lower than that of the corresponding equivalent cast-in-place floor, and the ability of their transmission of horizontal seismic is close, which can guarantee the collaborative work between different components resisting lateral forces in the model structure. Additionally, the matrix displacement method based on the "series-parallel lumped mass system" of non-rigid floor was used, and the contrast analysis shows that the horizontal anti-thrust stiffness of the new assembled monolithic floor is close to that of the general assembly floor with 50 mm concrete in-situ surface.
