摘要：
In order to research the dynamic characteristic and impact coefficient of bridges under moving vehicle loads, a continuous rigid frame bridge is taken as a calculation model. The finite element model of the bridge structure is established by the finite element software Midas Civil, the vehicle load is approximately modeled as a triangular load, time history analysis method is used to analyze the continuous response characteristic of rigid frame bridge under moving vehicle loads, and the influence law of the impact coefficient of continuous rigid frame under vehicle load factors at different speed, different weights is analyzed. and put forward the corresponding conclusions, for the safety of bridge structures under moving vehicle loads applicability to provide a reference basis.
