【摘要】 论文对合肥市三孝口人行过街天桥实地进行振动幅值和振动频率的测试,主测振幅。选择了桥体南面1/4环部分的跨中和1/4跨两点作为测试点,分三种工况为四端同时上下人,在环形桥面上齐踏步走动,以及无人走动时的天然脉动等。通过各种工况测试结果的对比研究,得出环状桥体的一般振动规律,为以后的工程计算测量提供参考。环形桥体的振动特性在国内研究较少,因此该研究具有重要意义。更多还原

【Abstract】 This paper describes the test of vibration characteristics of amplitude and frequency for the Sanxiaokou Footbridge. Three test conditions, including walking up and down throughout four passageways, walking on the bridge floor and natural excitation, were taken into account. The measurements are compared with to get the general vibration patterns of the annular footbridges, as a reference for further engineering computations, measurements and constructions.更多还原
