【摘要】 为了准确掌握某混凝土简支T梁在役期间的实际承载力,判断桥梁结构是否满足安全使用规范,依据桥梁荷载试验规范,对被测混凝土简支T梁结构进行动静载试验,通过运用Midas/civil有限元分析软件进行计算并与试验结果比对,汇总静力荷载作用下桥梁的实测挠度、应变值、动力荷载作用下桥梁的频率等参数,总结对比各个参数的实测值与理论值,可以表明:本次检测混凝土T梁满足安全使用规范,满足安全使用的标准。更多还原

【Abstract】 In order to accurately grasp the actual bearing capacity of a simply supported concrete T-beam in service, and judge whether the bridge structure meets the safe use specifications, according to the bridge load test specifications, the dynamic static load test is carried out for the tested simply supported concrete T-beam structure. By using MIDAS/civil finite element analysis software to calculate and compare with the test results, the measured deflection, strain value and frequency of the bridge under static load are summarized. By summarizing and comparing the measured and theoretical values of each parameter, it can be shown that the concrete T-beam tested meets the safety use specification and the safety use standard.更多还原
