水平荷载作用下砌体墙-钢筋混凝土墙组合结构扭转的近似计算

Approximate Calculation of Torsion Effect in Composite Structure of Brick Walls and Reinforced Concrete Walls under Horizontal Load

扭转近似计算建立在平面结构及楼板在自身平面内无限刚性这两个基本假定的基础上.先作平移下的内力分析,然后考虑扭转作用对内力及位移作修正.提出在水平荷载作用下考虑扭转作用的剪力修正公式.公式简单实用,可用于水平地震作用下砌体墙-钢筋混凝土墙组合结构扭转的近似计算.

Approximate calculation of torsion effect is based on two basic assumptions that plane structure and slab are infinitely rigid in their own plane. First of all, internal force is analyzed under translation,and then internal force and displacement are modified considering torsion . Modified formula for shear under horizontal load is put forward considering torsion. The formula is simple and practical,and it can be used for approximate calculation of torsion effect in composite structure of brick walls and reinforced concrete walls under horizontal seismic loading.
