Structural Behaviour of Aluminium–Timber Composite Beams with Partial Shear Connections

نویسندگان

چکیده

In this paper, the short-term behaviour of innovative aluminium–timber composite beams was investigated. Laminated veneer lumber panels were attached to aluminium with screws. Recently conducted theoretical, experimental, and numerical investigations have focused on almost full shear connections. However, no experiments partial connections yet been conducted. For reason, action in different screw spacing studied paper. Four-point bending tests performed study their structural (ultimate load, mode failure, load versus deflection response, slip stiffness). The method used for steel–concrete connection adopted estimate bearing capacity investigated beams. resistance sagging from theoretical analyses differed by 6–16% laboratory tests. addition, four 2D models developed. One model reflected beam connection. remaining represented verified against test results. modelled as an orthotropic material its failure captured using Hashin damage model. only 3–6% lower than one experiments.

The Effect of the Slot Length on Beam Vertical Shear in I-Beams with Moment Connections

This paper evaluates the effect of slot existence with limited length between flanges and web junction of I-shaped beams at the region of moment connections on vertical force and shear stress distribution in beam flanges and web at connection section in comparison with classical theory of stress distribution. The main purpose of this research is to evaluate the efficiency of the slot in connect...

Structural behaviour of RC beams with external flexural and flexural–shear strengthening by FRP sheets

This paper presents experimental research on reinforced concrete (RC) beams with external flexural and flexural–shear strengthening by fibre reinforced polymer (FRP) sheets consisting of carbon FRP (CFRP) and glass FRP (GFRP). The work carried out has examined both the flexural and flexural–shear strengthening capacities of retrofitted RC beams and has indicated how different strengthening arra...

Finite Element Instability Analysis of the Steel Joist of Continuous Composite Beams with Flexible Shear Connectors

Composite steel/concrete beams may buckle in hogging bending regions. As the top flange of I-beam in that arrangement is restricted from any translational deformation and twist, the web will distort during buckling presenting a phenomenon often described as restricted distortional buckling. There are limited studies available in the literature of restricted distortional buckling of composite st...

Influence of Shear Connection Distributions on the Behaviour of Continuous Steel-concrete Composite Beams

For this purpose a finite element model specifically developed for the nonlinear analysis of steel-concrete composite beams is adopted. This finite element model includes material nonlinearity of slab concrete, reinforcement steel, beam steel as well as slabbeam nonlinear partial interaction due to the deformable shear connection. The inclusion of the partial interaction in the composite beam m...
