Abstract

The shape of heterotypic spatial plate and shell structure is irregular, the performance of force is complex, so it is necessary to analyze the stress performance for this heterotypic spatial plate and shell structure, and understand the stress characteristics. By using the finite element program MIDAS to analyze its mechanical properties in elastic stage, and put forward the deformation coefficient of K to embody the deformation performance of spatial plate and shell structure. Through analyzing the influence factors, such as inclination of shell, concrete strength and thickness of shell, to effect mechanical properties of the heterotypic spatial plate and shell structure.
