| 中文摘要: |
| 以某敞开式桁架组合简支梁桥结构为工程背景，基于车桥耦合振动分析理论，采用一种简化的车桥耦合振动分析方法，对该公路桥进行车辆荷载作用下的振动响应分析。分析研究了四种行车方式、六种行驶车速下组合桁架梁桥的振动响应。分析结果表明，该桥梁的各项动力指标满足设计安全要求。分析方法可为类似敞开式桁架组合简支梁桥结构设计提供参考。 |
| 英文摘要: |
| Taking one open type truss composite simply supported beam bridge as the engineering background, the vibration response analysis under vehicle load has been done by using a simplified analysis method based on theory of vehicle-bridge coupling vibration analysis. The vibration response of the composite truss beam bridge has been studied under four driving modes and six types of driving speed. The analysis result shows the dynamic parameters of bridge can meet the designing safety requirements. The analysis method can provide reference for the design of similar open type truss composite simply supported beam bridge. |
