摘要: Abstract In this paper, a theoretical calculation method that can be generally applied to responses analysis of irregular bridge span pontoon connected by elastic hinges was proposed based on the foundation beam theory. This solve displacements, rotation angles, bending moments and shear forces under vertical static loads. By comparing with experimental numerical results in other researches, correctness universality are verified. The main response characteristics loads further investigated detailed case study, which contrasts three methods including AQWA software FEM. reveal stiffness has great influence bridge. deformation units ignored when is small, while it needs considered seriously reaches certain value. Besides, flexural rigidity also sensitive results. provide for optimal design significant engineering application prospects.
