Summary: | The invention relates to a method for analyzing the influence of an arch bridge girder erection sequence on an arch rib, which comprises the following steps of: establishing a chain relation of girder erection sequence-girder piece load-supporting load-structural response by adopting an influence matrix method, and determining whether a proposed girder erection scheme is reasonable and feasible; wherein the structural physical quantity comprises nodal displacement, unit internal force, section stress or a linear transformation value between the physical quantities. According to the method, the beam erecting sequence matrix, the beam piece and support relation matrix and the support-to-structure influence matrix are determined through the influence matrix method, so that the beam erecting sequence-beam piece load-support load-structure response chain relation is established, the support is used as unit force instead of the beam piece based on the chain relation, the finite element calculation amount can be gre |
