摘要:
桥梁结构的动力特性是结构动力反应计算和抗震分析的基础.本文运用Algor有限元计算软件中的空间板单元,对一座建成已一年多的预应力混凝土连续箱梁桥进行了动力特性理论分析,并通过现场实测对理论分析结果进行了比较.结果表明理论与实测的前几阶结构动力特性基本吻合,用脉动法对桥梁结构的动力特性进行测试是有效的.另外,现场跑车试验发现桥面平整性不好加剧了车辆对桥梁结构的冲击,这在桥梁的后期养护中应引起足够重视.
Abstract:
Dynamic characteristics of bridge structure are the base of dynamic responses calculation and aseismicity analysis. Based on Algor finite element method, three-dimensional plane element is adopted in theoretic dynamic analysis of a practical box girder bridge which was constructed more than one year age, and the result is compared with that of practical test. It shows that the dynamic properties of the first steps by theory essentially agree with that by practical test, and that the impulse response method is efficient in dynamic test of bridge. Running truck experiment indicates that bad pavement aggravates the impact of vehicles against bridge structure,which should be paid enough attention to in maintenance.
