考虑相关影响的弯扭构件承载力计算探讨

On calculation of bearing capacity of concrete member subjected to bending torsion with consideration of related influence

阐述了国内外弯扭受力构件的计算模式及弯扭的破坏机理,对变角度空间桁架模型所提出的受扭强度计算公式与国内外弯扭理论进行研究,在不同扭弯比情况下考虑弯扭相互影响,采用弯扭影响系数对弯、扭复合受力钢筋混凝土构件进行承载力计算。

The calculation model and failure mechanism of the member sub- jeeted to bending-torsion at home and abroad were described. The calculation formula of bearing capacity based on a variable angle space truss model and theories of bending-torsion at home and abroad were studied in this paper. Taking into account the interrelation of bending and torsion in conditions of different torsion-bending ratio, the influencing factor of bending-torsion is adopted to calculate the bearing capacity of the concrete member subject to bending-torsion.
