摘 要: | 我国《混凝土结构设计规范》(GB 50010-2002)首次明确提出要计算协调扭矩。基于线弹性分析法,对支承楼面次梁的现浇钢筋混凝土框架结构边梁的协调扭矩计算进行了探讨。利用位移法和杆件的扭转计算,以及考虑静力平衡条件和变形协调条件,推导出任意荷载下的非对称的钢筋混凝土框架边梁协调扭矩的计算公式,方便设计人员对钢筋混凝土框架边梁按弯剪扭构件进行承载力计算。

Abstract: | Computation of compatibility torsion is presented first definitely for The Code for Design of Concrete Structure ( GB 50010-2002). Based on the linear elastic analysis method, calculation of compatibility torsion is discussed for the edge beams of cast-in-situ R. C. frame structure supporting secondary beams. Using displacement method and torsion calculation of member, considered equilibrium conditions and deformation compatibility conditions, the formula for calculating compatibility torsion of asymmetric R.C. edge beams of frames under arbitrary loading is derived. Load-carrying capacity of R. C. edge beams of frames is designed by member of flexure-shear and torsion, it is useful and convenient for designers. |
