| 摘 要： | 在桥梁设计的内力分析中,横向分布系数的简化计算方法有多种.但通过荷载试验结果来分析桥梁在成桥状态下的实际横向分布系数,有待深入研究.本文通过对简支梁桥跨中挠度与横向分布系数之间的关系进行理论分析,认为可通过实测跨中挠度计算各梁的横向分布系数,并以某桥的荷载试验为例,以此分析成桥后梁与梁之间的实际横向联系效果.

| Abstract: | There are many simplified methods of the transverse distribution factor calculation in the inner force analysis during bridge design.However,it's a work need intensive study that analyzing the actual transverse distribution factor under the completion state of bridge through the load test results.In this paper,the relationship between midspan deflections and transverse distribution factors of simple supported bridge were theoretically analyzed.And the transverse distribution factor of each beam was considered computable through actual measured midspan deflections.The load test of a bridge was taken for example to analyze the actual transverse connection effects between the beams after the completion of the bridge. |

| Keywords: | simple supported beam bridge load test midspan deflection transverse distribution factor |
