结构设计中钢筋混凝土和钢结构构件的受剪破坏分析与校核

The Shear Failure Analysis and Checking of Reinforced Concrete and Steel Structure Members in Structure Design

通过钢筋混凝土构件受剪破坏形式、机理和受剪承载力影响因素的分析,分别对钢筋混凝土无腹筋板、有腹筋构件和深受弯构件的受剪破坏进行校核。只有同时避免钢筋混凝土构件三种受剪破坏,钢筋混凝土构件承受剪力才安全。对钢结构连接件和构件进行受剪分析和受剪强度校核,得出钢结构连接件和构件受剪强度校核不满足,增加钢结构连接件和构件的截面面积最有效的方法。

Through the shear failure mode,the mechanism and shear capacity influential factors of reinforced concrete members are analyzed; the shear failure of reinforced concrete slab without web reinforcement,reinforced concrete members with web reinforcement and the reinforced concrete deep flexural member are respectively checked. Only while avoiding three shear failures of reinforced concrete members at the same time,reinforced concrete members bearing shear was safe. For the shear analysis and the shear strength check of the steel structure connecting pieces and members,it is concluded that the shear strength check of the steel structure connecting pieces and members do not meet,and the increase of the steel structure connecting pieces and member cross section area is the most efficient method.
