剪力墙优化选型初探

Discussion on the Optimization of Shear-wall Structure

剪力墙一般结构刚度大 ,整体性好 ,建筑上易于布置 ,但其自重及刚度大 ,引起的地震反应也较大 ,且结构本身的延性不好 .针对这种情况 ,从其力学特点出发 ,结合实际工作中的设计要求 ,提出用短肢剪力墙和异形柱的结构形式可以较好地满足结构整体刚度、承载力及延性变形能力达到最佳匹配的设计要求 ,并能方便地应用于实际设计工作中 .

The shear-wall structure has big stiffness, good wholeness, and it is easy to make architectural design. But the general shear-wall structure is always high in the weight and the stiffness, which causes bigger earthquake response, and the ductility of the structure itself is not good. For the increasing of ductility and the capacity of consuming energy of shear-wall structure, this paper puts forward the short-limb shear-wall and special-shaped column structure. Considering the mechanic property and the design requirement in actual work, the conclusion that using shear-wall and special-shaped column, the best design requirement of the whole stiffness, the bearing capacity and the capacity of ductility can be met, and it can be conveniently applied to the design work is drawn.
