Abstract

This study focuses on the flexural behavior of a composite construction consisting of three concrete filled steel tubular (CFST) chords connected by a circular steel braces. The CFST members exhibit advantages such as stiffness, strength, capacity, and ductility compared to conventional steel and reinforced concrete members. The study uses CATIA V5 software for modelling the truss specimens, and ANSYS software for finite element analysis. The main parameters examined include shear span ratio, angle between brace and chord, presence of infilled concrete, subsequent flexural behavior, and material interaction. The moment of resistance of the CFST truss with braces is calculated using the working stress method, and a design table for ultimate load carrying capacity of different circular sections is generated. The study aims to understand the effects of shear span ratio, angle of chord, brace, and presence of infill concrete on the CFST chord and brace girder.

挠曲荷载下混凝土填充钢管弦杆和支撑桥梁的分析与设计

本研究的重点是由三个钢管混凝土(CFST)弦由一个圆形钢撑连接的组合结构的抗弯性能。与传统的钢和钢筋混凝土构件相比，CFST构件具有刚度、强度、承载力和延性等优点。采用CATIA V5软件对桁架试件进行建模，ANSYS软件对桁架试件进行有限元分析。检查的主要参数包括剪切跨比，支撑和弦之间的角度，填充混凝土的存在，随后的弯曲行为和材料相互作用。采用工作应力法计算了带支撑的钢管混凝土桁架的阻力矩，生成了不同圆截面的极限承载能力设计表格。研究的目的是了解剪跨比、弦角、撑角和填充混凝土的存在对钢管混凝土弦、撑梁的影响。
