【摘要】 选用大型有限元软件MIDAS/Civil建立一般平面杆系结构模型,用刚接梁法计算T梁的荷载横向分布系数.并且考虑了横隔梁、桥面板宽度、桥面板厚度、主梁翼板厚度、混凝土的弹性模量和中横梁换算成单位长度的截面惯性矩这6个方面,对模型中影响荷载横向分布系数的因素进行了灵敏度分析,可以为工程计算所参考.更多还原

【Abstract】 In this paper,the model of the general plane structure is established by the finite element software MIDAS/Civil and the load transversal distribution factor of T-beam is calculated by rigid-jointed beam method.This paper takes into account the impact of diaphragm,the width of bridge deck,bridge deck thickness,girder wing thickness,the elastic modulus of concrete and section inertia moment of middle transverse beam converted into per unit length.This paper also analyses the influencing factors of load transversal distribution factor by sensitivity,which can be referred to as the projeat calculation.更多还原
