AbstractThe dowel action of reinforcing steel bars crossing cracks is modeled for the finite element analysis of reinforced concrete. In the proposed model, the dowel forces and displacements are smeared over the element respectively in order to be consistent with the smeared crack and reinforcement models. The dowel action model is incorporated in a finite element procedure with displacement controlled iteration scheme and secant stiffness formulation, so as to deal with the post-peak behavior of reinforced concrete structures. The analytical results on deep beams agree closely with test data. It is concluded that the dowel action of reinforcing main bars has a significant contribution to the strength and ductility of shear critical members.
本文提出了一個用于有限元分析的鋼筋銷栓作用模型。該模型采用分布模式來處理鋼筋的橫向銷栓力和橫向變形,以便與鋼筋的整體式模型和混凝土的分布裂縫模型相協調。在有限元分析中采用了位移控制的割線剛度迭代法,可以進行荷載位移曲線下降段的分析計算。對深梁試件的分析表明,本文提出的鋼筋混凝土模型可以準確分析試件的荷載變形特性。同時發現,縱向主筋的銷栓作用對深梁的承載力和變形能力都有重要的影響。
