广义预应力技术在复合受扭构件中的应用研究

Application research of broad-sense pre-stress technology in RC members subjected to combined torsion

介绍等效荷载的概念和性质,在广义预应力概念的基础上,结合钢筋混凝土纯扭构件中配置预应力筋抵抗扭矩的相关研究成果,提出以广义预应力技术解决钢筋混凝土复合受扭构件抗扭问题的设想,经过理论分析给出抗扭预应力筋的配置形式。

It introduces the concept and characteristics of equivalent loads, On the basis of the concept of broadsense pre-stress, combined with relative achievements in RC members with anti-torsion pre-stressed tendons and subjected to pure torsion, it presents the idea of using broad-sense pre-stress technology to resist combined torsion. Finally it gives the form of anti-torsion pre-stressed tendons.
