摘要:
在试验的基础上,考察了在低周反复荷载作用下L形柱所产生的扭转效应,并借鉴规范对复合受力构件剪扭承载力的计算方法,定量地分析了附加扭矩对L形柱所产生的影响。研究结果表明:单个L形柱和结构中的L形框架柱受扭性能不同,前者对水平荷载的加载角度表现敏感,非对称加载时,附加扭矩的影响不可忽略,设计中应考虑弯剪扭的复合作用; 而后者作为结构中协同工作的一部分,抗扭性能明显改善。
Abstract:
The torsion effect of L-shaped column under low cyclic loading was discussed based on the experiment. The bearing capacity calculation method of shear and torsion of component under combined forces was gained by referring to standard, at the same time, the influence of additional torque to L-shaped column was quantitatively analyzed. The result shows that the torsion performance in single L-shaped column is different with that in column frame; the former is sensitive to loading angle of horizontal load, and its additional torque influence can not be ignored under asymmetric loading, meanwhile, the composite action of bending, shear and torsion in design should be considered in terms of the re-torsion capacity of latter, as a part of the structure that works together is advanced obviously.
