摘要:
利用考虑滑移的钢-混凝土组合梁单元,建立了考虑滑移的钢-混凝土组合梁有限单元法.在粘结剪力和滑移微分控制方程的基础上,建立了关于组合梁单元杆端未知力的力法方程.在力法方程的基础上,给出了组合梁单元的刚度矩阵、杆端位移向量及杆端荷载向量并建立了刚度方程.为验证有限单元法的正确性,对试验梁进行了跨中挠度、沿梁高应变分布及梁端滑移的计算分析.计算结果表明,所建立的考虑滑移的钢-混凝土组合梁有限单元法与试验值吻合较好,计算结果可靠.
Abstract:
Based on displacement-based finite element models proposed, a finite element(FE)method of steel and concrete composite beams considering slip between steel girder and concrete plate is presented. A force-method equation about unknown nodal forces of the composite beams is proposed based on the governing differential equation. Based on the force-method equation, the stiffness matrix and fixed-end nodal displacement and force vector are derived. The proposed model is compared with experimental beams in the midspan cross-section deflections, strain distribution and the slip of supporting points. It is shown that the calculation results by the proposed method are in close agreement with the experimental results.
