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.
