框-剪结构考虑剪力墙剪切变形影响的剪力墙合理数量

Optimal quantity of shear walls in frame-shear wall structures considering influence of shear deformation of shear walls

基于框-剪结构协同工作的连续化分析原理,文章得到了考虑剪力墙剪切变形影响的框-剪结构刚接体系的剪力墙合理数量计算式,并与不考虑剪力墙剪切变形影响的铰接体系和刚接体系的计算式进行比较,分析了它们在确定剪力墙合理数量上的相似和不同。通过算例讨论了框-剪结构的具体剪力墙合理数量值,分析了剪力墙剪切变形和连梁约束刚度对其影响程度,并得出剪力墙的剪切变形对剪力墙合理数量的影响比连梁约束刚度弱;考虑剪力墙剪切变形影响的刚接体系的剪力墙合理数量比不考虑剪力墙剪切变形影响的铰接体系和刚接体系均少,使得结构在安全前提下更加经济合理。

Based on the principle of the continuous analysis of interactive frame-shear wall structures, a series of formulas of optimal quantity of shear walls for rigid connection system considering the shear deformation effect of shear wall were deduced, and then compared to formulas of hinged connection system and rigid con- nection system which did not consider the shear deformation effect of shear wall. The similarities and differences of these three systems in detemaining the optimal quantity of sl＇iear walls were analyzed. The optimal quantity of shear walls was discussed through examples, showing the effect of the shear deformation of shear wall and the constrained stiffness of connecting beam on it. Some conclusions are summarized that the effect of the shear deformation on the optimal quantity of the shear wails is less significant than that of the constrained stiffness. The optimal quantity of shear walls for rigid connection system considering the shear deformation effect of shear wall is less than that of the other two systems, which makes structures more economic and reasonable under the premise of safety.
