摘要:
对钢与混凝土组合梁扭转进行了探讨,提出了以开口薄壁杆件的约束扭转理论为基础的扭转极限分析方法.首先,对组合梁扭转问题进行了讨论,确定其分析方法; 将组合梁计算截面进行等效,以便于利用开口薄壁杆件的约束扭转理论对其进行分析,并示意了等效截面在约束扭转力矩作用下的应力分布情况; 提出了组合梁扭转的近似上下限分析方法,其中,前者计算简单,适用于设计,而后者较为繁琐,可作为前者的一个校验标准; 最后,通过例题将这2种方法进行了演示.
Abstract:
The torsion of composite beams of steel and concrete and the limit analysis based on the theory of twisted members with thin-walled open section and restraint of warping are discussed. In order to analyze the torsion by the theory of thin-walled member under restricted torsion, the calculated section is transformed into equivalent cross section, and the stress distribution on it is shown while some torque acts on the beams. After that, the approximate analysis methods of upper bound and lower bound are illustrated, the former is simple and suited for design, while the latter is much more complicated. Finally, the two ways are demonstrated by the example.
