Flexural Response of Steel‐Concrete Composite Truss Beams

Abstract: This paper presents an experimental and analytical study on the flexural response of a steel-concrete composite truss beam. This integrated unit consists of a triangular steel truss, a concrete slab on it, and stud connectors. Three simply supported composite trusses with different configurations of shear connection (η) were evaluated via three-point bending tests. The effects of the shear connectors’ configuration on the flexural response (i.e., load-deflection, load-slippage, and load-strain curves) of the c… Show more

“…To better obtain the working mechanism of the modified through-core connections, finite element models of the tested specimens were established using ABAQUS [16]. Following its validation with the experimental results, the internal stress stage and cooperative working mechanism during the loading process were discussed, and then a parametric study was performed using varying critical parameters in Section 4.…”

“…Since the mesoscale study of concrete mechanical behaviors can obtain a more fundamental understanding of concrete damage and failure mechanisms and provide a deep insight into macroscopic mechanical behaviors, it has become a hot research area of concrete material and achieved fruitful results. Up to date, the finite element method (FEM), which helps many researchers to simulate the effects of multiphase distribution on the mechanical response and damage properties of concrete [5][6][7][8][9][10][11][12][13][14][15][16][17][18], is still being a dominant method to model different behaviors of concrete at macro-and mesoscales. However, with the development of computing technology and numerical methods, more and more approaches are being employed to explain the damage mechanism of concrete structure [19][20][21][22][23][24][25].…”
