墙-框架耦联结构分析中关于梁—墙节点转角的定义在墙-框架耦联结构分析中,对梁-墙节点转角曾用过几种不同的定义,然而,所用的各种定义是不等效的。通过将耦联梁单元按每端都有水平和垂直纤维转动的Timoshenko梁单元来表示,说明梁-墙节点的转角应正确地定义为梁-墙交界面处垂直纤维的转角,而其它定义则可能导致耦联梁有效刚度方面的误差。定量评估这样引起的误差发现,对于短而刚的耦联梁,误差可以非常大。因此建议,对那些有别于垂直纤维转角定义的现有方法应进 In the wall-frame coupling structure analysis, the definition of the angle of the beam-wall joint is used in the analysis of the wall-frame coupling structure. Several different definitions have been used for the angle of the beam-wall joint. However, the various definitions used are not. Equivalent. This is illustrated by the Timoshenko beam element with horizontal and vertical fiber rotations at each end of the coupling beam element, indicating that the angle of the beam-wall joint should be correctly defined as the vertical fiber angle at the beam-wall interface, while other definitions This may cause errors in the effective stiffness of the coupling beam. Quantitative assessment of the resulting errors found that for short and rigid coupling beams, the error can be very large. It is therefore recommended that existing methods that differ from the definition of vertical fiber angles should be developed
