Analysis on Static Behavior of Open Web Arch Steel Frame

XU Xiang-dong

Abstract

Under vertical loads,space beam finite element method is used for 13 example of this structure fixed translational DOF of boundary node,the influence of deformation and internal force with height-to-span and thickness of shell are discussed.The analysis results show that when its height-to-span is 1/4～1/6,its strength index and stiffness control are ideal;The changes on static behavior are very small with thickness.This paper compare the open web arch steel frame and single-layer arch steel frame and shows arch steel frame can be analyzed by single-layer arch steel frame which is changed by axial stiffness,its can be used in the control of strength and stiffness when preliminary designing.The conclusions of the text can offer reference for the application of similar projects.
