| 摘 要： | 同时对预应力混凝土简支梁进行了破坏性加载试验和振动信号采集工作。由静载数据可知梁跨中受集中力的初裂荷载为 50 0 k N～ 550 k N,满足设计要求。分析构件在受力损伤过程中的动力响应有关参数变化并对静、动检测时梁性能的各有关参数进行比较 ,可为今后桥梁无损检测提供参考

| Abstract: | At the same time,destructiveness test by loading on simple supporting prestressing concrete beam and gathering work of the vibration signal were carried on.By the data from the static load test,It could be concluded that load at the beginning in strength split was from 500kN to 550kN while the beam was enduring the centralized load in the middle of the span.It was satisfied with the designing requirements.What has been analyzed that parameter change about the dynamic respond in the coures of damaging,and compared the parameter change of the beam performance under the static and moving load test.It may provide the reference for the harmless measure of the bridge in the future. |
