摘要:
介绍了已有的弯扭相关关系,并与试验结果做了初步的比较; 根据极限状态下工字钢梁的剪应力和正应力的分布,由力的平衡关系得到了其剪扭和弯剪相关关系,并通过试验获得的数据对已有的弯扭、弯剪扭统一相关关系以及本文推导的相关关系作了比较和分析,证明本文方法不仅安全合理,而且简洁明了,使用方便.最后,在作了一些假设以后,将这种相关关系引入到钢与混凝土组合梁的设计中.
Abstract:
The previous correlativity of combined bending and torsion is introduced and it is compared with the experimental result preliminarily. Based on the distribution of shear stress and normal stress at limit state on I-section beams, the correlativity of combined shear and torsion and combined bending and shear are obtained through the section equilibrium. Experiment data verify that the correlativity deduced in this article is not only reasonable and safe, but also simple and convenient in application, compared with the solo correlativity of bending-torsion and the integrate correlativity of bending-torsion-shear. At last it is applied to the design of steel and concrete composite beams under some hypotheses.
