【摘要】 建立了基于静力荷载试验的连续箱梁桥结构有限元模型修正方法.该方法主要包括实桥静力荷载试验、桥梁结构有限元建模、有限元模型参数修正等步骤.利用该方法对某高速公路五跨预应力连续箱梁桥进行有限元模型修正,得到了与桥梁实际静力荷载试验实测响应一致的桥梁结构静力有限元模型.经过修正的桥梁结构有限元模型(参数)是桥梁结构性能评价等结构分析工作的基础.更多还原

【Abstract】 A method for continuous box-girder bridge structure finite element(FE) model updating based on static-load testing is proposed.The procedure includes field static-load testing,FE modeling,FE model(parameter) updating,etc.Based on this procedure,the structure FE model updating for an expressway 9-span pre-stressed concrete continuous box-girder bridge is conducted.And the bridge structure static FE model,which is consistent with the static-load testing actual measure response,is gained.The updated FE model(parameter) is foundation of structural performance evaluation for the bridge.更多还原
