Web Sandwich, Square Reinforced Concrete Orthogonal Curvature Shallow Shells Static And Stability Analysis

Open-Web Sandwich Shell of steal and concrete structural system is a new kind of space structural system, which bases on the Open-Web Sandwich Plate of steal and concrete structural system and shell structural system. Open-Web Sandwich Shell structural system combines the advantages of the two systems and makes good use of them, so it can make a larger span economically and reasonably. At present the study in this field is blank in our country and no examples of projects.This paper take large-scale general finite element analysis software ANSYS as a tool, carries on a more detailed static and the stability analyses to the Open-Web Sandwich Shell of steal and concrete structural.Has analyzed the grid number, the upper and lower rib section size, shear keys section size and a high degree, and edge component propertie of static using ANSYS. The edge component of a greater impact on the structure. Edge component in ensuring adequate stiffness circumstances, the structure of shell of the mechanical properties, which make up the the Open-Web Sandwich Plate of steal and concrete bending rigidity of the shortcomings too small, reflects the spatial structure of the bar in the space distribution To achieve "no moment" philosophy, to effectively improve the utilization of materials.Open-Web Sandwich Shell of steal and concrete structural of the characteristics of buckling analysis and nonlinear analysis of buckling using ANSYS. Had understood initially the structure flexure performance and the destruction process, and has carried on the load - displacement' s entire process analysis to the example, after studying its achievement ideal flat network shell the stable performance and passes through the flexure structure displacement shape.
