| 中文摘要 | 对某景观桥进行了检测评定,提出了3种加固方案,并采用大型通用有限元软件ANSYS建立了桥梁上部结构模型以及3种加固方案的模型,其中加固方案模型建立于根据静载试验数据修正后的模型之上;利用该模型进行了设计荷载工况下的静力分析和模态分析,并根据计算结果比较了3种加固方案以及参数变化对桥梁挠度、支座区最大等效应力、极限承载力以及动力特性的影响。结果表明:综合采用加固方案1和加固方案3是比较合理的。; Three strengthening schemes were presented according to the inspecting and appraisal results of some sight bridge.The models of the upper structure of the bridge and three strengthening schemes were presented by using large finite element software ANSYS.Then,the finite element models of upper structure of the bridges and three strengthening schemes,which were updated by the data of static loading test,were built.The static analyses and modal analyses were executed by the models and influences of three strengthening schemes and the corresponding parameters on the deflection,maximum equivalent stress in support region,the ultimate bearing capacity and the dynamic characteristics of the bridges.The results show that it's reasonable to synthesize strengthening scheme 1 and strengthening scheme 3.; “十一五”国家科技支撑计划重大项目(2006BAJ03A02); 高等学校科技创新工程重大项目培育资金项目(704003) |
