摘要:
对同时承受弯矩、剪力和扭矩的复合受扭钢筋混凝土箱梁构件进行配筋设计.以给出的弯剪扭设计荷载为已知量,底板受拉纵筋和腹板箍筋面积为未知量,通过引入箱梁剪、扭应力叠加侧腹板单元体的平衡方程、协调方程及本构关系,采用迭代方法求解所需钢筋面积.共设计了4个复合受扭钢筋混凝土连续箱梁模型构件,其中构件L1和L3按照所提的迭代方法设计配筋,在此基础上分别增大底板受拉纵筋和腹板箍筋面积得到构件L2和L4.破坏试验结果表明:构件L1和L3的开裂形态、破坏模式和钢筋屈服状态与所提的设计方法吻合较好,构件L2和L4则表现出不同程度的部分超筋破坏.
Abstract:
Reinforcement design of reinforced concrete(RC)box girders subjected to combined action of bending, shear and torsion is carried out. The given design loads of bending, torsion and shear are taken as known parameters, and the areas of longitudinal tensile reinforcement in the bottom plate and stirrup in webs are regarded as unknown parameters. By introducing the equilibrium equations, compatibility equations and constitutive relations of the web in which the shear force and torque are superimposed, the required reinforcement areas are obtained by using the iterative method. Four models of RC continuous box girders subjected to combined torsion are designed. Models L1 and L3 are designed based on the proposed method, while models L2 and L4 are obtained through increasing the areas of longitudinal tensile reinforcement in the bottom plate and stirrup in webs, respectively. The experimental results show that the crack patterns, failure modes and reinforcement yield state of models L1 and L3 are in good agreement with those in the design ideas, while models L2 and L4 exhibit partial over-reinforced failure in different degrees.
