摘要
目的研究框架-密肋复合墙体的构造形式与受力特点及在水平荷载作用下其顶部位移的简化计算方法.方法以框架与复合墙的并联机制为协同工作模型,以框架结构的位移计算方法为依据,考虑弹性状态中后期填充砌块开裂情况,根据材料力学和结构力学基本理论提出框架-复合墙体的力法位移方程,并利用型钢混凝土外框柱-密肋复合墙的试验结果对位移方程进行验证.结果框架-复合墙体的力法位移方程与一般框架、混凝土墙位移方程有着良好的相容性;框架-复合墙体的剪切变形在总变形中所占比重较大,中高层框架-复合墙结构侧移曲线呈现明显的弯剪型特征.结论提供了一种框架-密肋复合墙体位移计算方法,可供该结构体系的实际工程设计参考.
According to the special forms and mechanical behavior of frame-composite walls, displacement calculation method for frame-composite walls under horizontal loads is proposed in this paper. The model of frames and composite walls in parallel is adopted for considering working together of them. Cracking of filling blocks at middle and end elastic stages is taken into account. Based on material and structure mechanics theories, the displacement calculation method of frame-composite walls is derived from that of frame structures. The calculation results of the proposed method agree well with the test results of multi-ribbed composite wall with edge frame columns reinforced by steel. The displacement calculation method of frame-composite walls is compatible with that of frames and that of RC shear wails. The shear deformation of the framecomposite wall contributes most to the whole deformation. And the lateral displacement curves of middle to high-rise frame-composite wall structures are characterized by flexure-shear deformation. The proposed displacement calculation method for frame-composite wall structures can be used as a reference for structural design.
