| Abstract: | Using finite element model of whole bridge,the author carries out response spectrum analysis and elastic time interval analysis of 32 108 32 m half-through steel box arch bridge in Jinghu high speed railway,and the result shows that earthquake-resistant behavior of this bridge comforts code requirement and its selected structural configuration and size of section are reasonable and feasible. |
