16m预应力空心板简支梁桥成桥动载试验及分析

Completed bridge dynamic load testing and analysis of 16 m prestressed hollow slab simply supported girder bridge

介绍了16 m预应力空心板简支梁桥的成桥动载试验,根据成桥动载试验的结果,分析了桥跨结构的竖向受迫振动响应、垂向激励引起桥梁的强迫效应、纵向振动响应、自振频率、振型和冲击系数等动力特性,结果表明:各项性能指标均在正常范围内。

The completed bridge dynamic load testing of 16 m prestressed hollow slab simply supported girder bridge was introduced. Based on the results of completed bridge dynamic load testing, the dynamic characteristics such as vertical forced vibration of bridge span structure, foreing effect of bridge beam caused by vertical motivation, axial vibration response, natural frequency, vibration mode and impact coefficient were analyzed, the results showed that every performance index was in normal range.
