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.
