Abstract

An algorithm especially for analyzing complex slabs of buildings in finite element method is proposed in this paper, which can improve the stress precision and obtain accurate and reliable analysis results. First, a general thin-thick plate element with the quadrilateral area coordinate is employed, which avoids shear locking and distortion; Second, based on paving method, an algorithm for quadrilateral mesh is designed, which can achieve high-quality results and improve the stress precision significantly. This algorithm has been already implemented and integrated in Paco, a software for structural design, independently developed by Beijing Institute of Architectural Design. With this improvement, smooth stress contour of complex slabs can be obtained and the precision is guaranteed.
