| 摘 要： | 以变角空间桁架理论为基础,在考虑莫尔应力协调条件下,提出了预应力混凝土纯扭构件破坏形态的判别准则,并建立了纯扭强度的计算方法.通过试验资料的验证,计算值与试验值吻合较好,并且具有较高的计算精度,因此,对预应力混凝土构件纯扭强度的计算方法进行进一步验证是十分必要的.研究预应力混凝土构件纯扭作用的机理和制定其强度的计算方法,是解决复合受扭强度计算的基础. |

| Abstract: | Based on the variable angle space truss theory,a failure criterion for pure torsion is presented and calculating method is established for ultimate pure torsional strength of prestressed concrete beams,which considers the mohr stress compatibility and the softened constitutive laws of concrete.Compared with the experimental results,the theoretic calculating shows a good agreement and high precision.Therefore it is necessary to carry on solution to pure torsional strength calculation of prestressed concrete structures.Researches on mechanism and developing their strength calculation method for prestressed concrete structures are the foundation of complex torsional strength calculation. |
| Keywords: | space truss prestressed concrete pure torsion calculation |
