近二十年来,对钢筋混凝土受扭构件的试验研究,尽管在国外做了许多工作,但由于构件处于非弹性的空间受力状态,而且往往又是复合应力问题,因而情况比较复杂,致使对构件的破坏机理及抗扭性能的理论研究尚不成熟。随着生产的发展以及工程中对高强材料和薄壁截面结构的广泛应用,对钢筋混凝土构件抗扭的研究,也有了进一步的 In the past two decades, the experimental research on the torsion members of reinforced concrete has done a lot of work abroad. However, because the members are in a non-elastic state of space stress, and they are often compound stress problems, the situation is more complicated, resulting in The theoretical study of the failure mechanism and torsional properties of components is not yet mature. With the development of production and the extensive application of high-strength materials and thin-walled cross-section structures in engineering, there has been further research on the torsion resistance of reinforced concrete structures.
