RESEARCH ON APDL-BASED BRIDGE PARAMETRIC FINITE ELEMENT ANALYSIS METHOD
摘要
Abstract
For the disadvantages of previous bridge modelling methods that they are more complex and cost a longer time,as well as the technical problems of finite element analysis being out of line with the modelling process,we proposed a parametric modelling method by tak-ing A-shaped towers of concrete cable-stayed bridge as the example,which is based on boundary characteristic constraint of bridge tower point cloud model.Then we used the parametric design language APDL to write the programs,making the parameterisation be inherited in finite el-ement analysis process.The biggest peculiarity of this method is to build the finite element model of the bridge tower based on the characteris-tic boundary constraint parameter relationship of the point cloud model,then to load according to the actual stress loading conditions on the bridge tower,at the last we calculated the model and extracted the experimental results.Experimental results show that this method could quickly build the parameterised model of bridge tower and improved the effectiveness of finite element analysis,and then the stability analysis of the bridge tower structure could be derived,which provided the correlated basis for bridge health protection.关键词
