摘要
现行<混凝土结构设计规范>(GB50010-2002)规定,钢筋混凝土矩形受扭构件承载力计算一般采用"叠加法"进行,在一定程度上忽视了构件材料强度以及弯矩大小对构件破坏的影响.为了保证结构安全性能又能节约经济,建议在钢筋混凝土矩形受扭构件承载力设计时,应充分考虑构件材料强度的变化影响,不论构件在多大的弯矩、剪力和扭矩作用下,都须以满足受弯承载力为主,相应再考虑构件扭矩的作用.
Nowadays, the present Code for Design of Concrete Structure （GB50Ol0-2002） stipulates that the calculation of bearing capacity of torsion member in reinforced concrete rectangle should commonly adopt the way called reiteration. But this way, to a certain degree, neglects some damage effects of material strength and rectallgle curvature to the member. In order to surely achieve both safety and economy, the design to the bearing capacity of torsion member in reinforced concrete rectangle should fully consider the changeable effects of material strength. Bearing capacity should be firstly considered, then the power of member torsion, no matter how powerful of the curvature, shear or torsion to the structural member.
