چکیده
Finite element (FE) model updating can guarantee the accuracy of numerical analyses for civil structures. However, two deficiencies currently exist with traditional FE technique based on measurements modal parameters and/or static structural responses built structure respect to its reference information insufficiency and non-unique solution generally obtained, hampering extensive use. It becomes goal whole engineering community introduce new effective methods update. To this end, an innovative method using data from construction monitoring is proposed in article. With regard theoretical novelty, transforms complicated multi-variable optimization mathematical problem into many simple single-variable parameter identification problems. Under background Huangsha Harbor Bridge, a three-span concrete continuous box girder bridge constructed utilizing symmetric cantilever casting method, effectiveness efficiency practice were validated. demonstrated quantitative that abundant measured Bridge stages enhance more accurate structure, uncertain initial be progressively easily identified linear regression models, instead one or employed by approaches, which leads solutions rendered normal algorithms.

In this paper, condition monitoring of a geared rotor system using finite element (FE) model updating and particle swarm optimization (PSO) method is onsidered. For this purpose, employing experimental data from the geared rotor system, an updated FE model is obtained. The geared rotor system under study consists of two shafts, four bearings, and two gears. To get the experimental data, iezoel...
متن کاملOptimization of Precast Prestressed Concrete Bridge Girder Systems
60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...
