摘要:
平铰拱桥结构的受力分析属于边界非线性力学问题，目前的一些方法受力分析不太明确，对变截面、复杂形状截面等平铰拱桥无法进行计算.针对这种情况，提出了确定平铰截面抗力系数K的新方法，建立了计算平铰拱桥内力的迭代算法，并进行了实例计算，研究结果表明，这一方法对具有任意个平铰、任意形状截面的拱桥结构是适用的.
Abstract:
The force analysis of the flat hinged arch bridge structure belongs to the boundary nonlinear mechanical problem, and the force analysis of some current methods is not clear, and the flat hinged arch bridge such as variable section and complex shape section cannot be calculated. In view of this situation, a new method for determining the resistance coefficient K of flat hinge section is proposed, an iterative algorithm for calculating the internal force of flat hinge arch bridge is established, and an example calculation is carried out, and the research results show that this method is applicable to arch bridge structures with arbitrary flat hinge and arbitrary shape cross-section.
