To improve the efficiency of finite element analysis and calculation on building structure,a quadrilateral mesh generation algorithm of building structure model is proposed. Firstly,the index information of structure model is quickly established using an improved binary search algorithm. Secondly,the boundary of the model is adjusted according to the generation principle of quadrilateral mesh. Lastly,the quadrilateral meshes are generated for the whole structure model by using the separated-region template method. The example shows that the algorithm can simplify the model according to the characteristics of the model in finite element analysis and calculation and shorten the computing time.
