框架-复合剪力墙结构水平位移计算方法研究

框架-复合剪力墙结构是由剪切型框架和弯剪型密肋复合墙组成的双重抗侧力体系，复合墙的受力特点决定结构位移计算方法不同于一般框架-剪力墙结构。框架-复合墙体模型试验证明了结构的协同工作性能，在框架-剪力墙结构位移计算方法的基础上，引入密肋复合墙体的剪切变形，建立了框架-弯剪型复合墙结构在三种常见荷载形式下的水平位移方程，可视为框剪结构位移方程的广义表达形式。算例分析表明，框架-复合墙结构的剪切变形使总水平位移显著增加，且所占比例较大，位移计算必须计入剪切变形。将框架-复合墙结构与框剪结构进行比较，分析了两者在位移、刚度等主要力学性能方面的异同。研究成果为进行框架-复合墙结构抗震设计理论研究提供了基础。

Calculation Method Research of Horizontal Displacement on the Frame-composite Wall Structure

The frame-composite wall structure is the dual anti-lateral force system which consisted of shear type frame and shear flexural multi-ribbed composite wall. The mechanical characteristics of the wall determine that displacement calculation method of the frame-composite wall structure is different with the general frame-shear wall structure. The model experiment about frame-composite wall has proven the cooperative work performance of the structure. Based on the frame-shear wall structure, and considering the shear deformation of the composite wall, the horizontal displacement under three common load forms are established which can be regarded as the generalized expression form of the frame-shear wall structure. The example shows that the shear deformation is the important component, and the shear deformation must be taken into account in displacement calculate of the frame-composite wall structure. The similarities and differences in mechanical properties between the frame-composite wall structure and frame-shear wall structure are compared. The findings provide a theoretical fundamental to study its anti-seismic design theory further.
