torsion pendulum

Based on the experiment, this paper analyses the limitation of section in rectangular reinforced concrete elements subjectal to combined bending, shear and torsion and presentsthe practical formulae.

本文在试验研究的基础上，对钢筋混凝土矩形截面弯剪扭构件截面限制条件进行分析，提出了实用计算公式。

Compared with a few chief strength calculating formulas in shear and torsion in building code of reinforced concrete structure at home and abroad this paper makes an analysis of the resuts and obtains the differences between them,which can be reference for the study of calculation models and design methods in shear and torsion.

本文对国内外几个主要的钢筋混凝土结构设计规范中的剪扭承载力计算公式作了对比分析，从中得出它们之间的差异，供研究剪扭计算模式和设计方法时参考。
