钢筋混凝土剪力墙正截面承载力的简化计算

钢筋混凝土剪力墙通常采取两端集中配筋、腹板均匀配筋的方式,我国现行有关规范和规程给出了正截面承载力的近似计算方法,但具体计算要经过多次迭代,比较繁琐。基于正截面承载力叠加方法,提出了一个简化计算方法。计算结果表明,建议方法计算简便,与现行规范方法和理论方法的计算结果相比误差很小。

SIMPLIFIED CALCULATION METHOD TO DETERMINE THE FLEXURAL STRENGTH OF RC SHEAR WALL

For RC shear walls,the reinforcements are often concentrated at two flanges and distributed along the wall web.The different approximate flexural strength methods of RC shear wall are given both in Code for Design of Concrete Structures and Technical Specification for Concrete Structures of Tall Building.But these methods are too complicated to be used.This paper provides a simplified method based on the superposition theory.The example shows that the suggested simplified method is easy to be used and has little error as compared with the theoretical results and that of Code for Design of Concrete Structures.
