摘    要:应用简支梁振动理论、推导出由冲南喷激振作用下测得的 支梁桥的自振频率f0以此得出各主梁在外荷载作用下的跨中挠度的计算方法,并对两座配筋砼简支梁桥的动载试验数据进行了实例计算,将计算结果,与采静载试验得得的跨中挠度进行了比较,二者符合情况良好,这表明采用既经济又简便的动载测试方法来确定等截面简支梁刚度是可行的。

关 键 词:配筋砼简支梁桥  动载测试

Abstract:The simple beam vibration theory was used to derive calculation method for the mid-span deflections of every beam under external loading conditions. based on the natural frequency f0 of the simple beam bridge measured under shock loading conditions. Calculations based on dynamic loading experimental results have been carried out. on a RC and a PC simple beam bridges. The results show that the calculated mid-span beam deflections agree very well with deflections obtained from static-loading experiments. This indicates that the economic and convenient dynamic loading experiment method can be used to determine the stiffness of constant cross-sectional simple beams.
Keywords:Dynamic loading experiment  Frequency  Deflection
