Abstract: Structural elements such as beam, plate and shell, are widely used in the finite element analysis. However, the geometric characteristics of structural elements may lead calculation errors in some cases. For example, when analyzing composite structures with structural elements, some problems such as stress concentration and improper simplification of the geometric position will induce rather large calculation errors. Taking the slab and girder composite structure in subway station as the analyzing object, the corresponding coun-termeasures are put forward for the purpose of engineering practicality. By using these measures, reasonable result can be obtained with general-purpose FEM software.

Key words: composite structure, stress concentration, slab and girder splice, finite element method
