Parametric study of I-shaped shear connectors with different orientations in push-out test

Abstract

A great deal of research has been conducted to improve the understanding of the behavior of new types of shear connectors. This article presents the study of I-shaped connectors behavior under monotonic load welded in four different orientations in order to get the position which gives the high shear strength and the best ductility. For this purpose, eight push-out test specimens with I-shaped shear connectors with different orientations and dimensions were tested in C20/25 and C30/37 concrete classes. The load-slip behavior and failure modes of the tested connectors are presented and discussed. Furthermore, a non-linear 3D finite element modelling of the push-out test is performed in order to further investigate the influencing parameters on the I-shaped connectors behavior. Hence, a parametric study is carried out by using the established 3D finite elements model to study the influence of concrete strength, connector’s steel grade, reinforcements, height and length of the connector. Both experimental and numerical results show that there is a privilege orientation for which the shear strength of an I-shaped shear connector is significantly higher than that of all other tested orientations.

Numerical investigation of the cold-formed I-beams bending strength with different web shapes

“…Fig. 16 shows the failure mode of the single web beam modeled with the ABAQUS software which was chosen because of its high performance and precision [19][20][21][22]24]. It is noted that the beam I has undergone a local buckling in the upper flange at the level of the zone of application of the load in addition to a distortional lateral buckling.…”

“…The basic concept of finite element analysis is that a structure is divided into a finite number of elements having finite dimensions and reducing the structure having infinite degrees of freedom to finite degrees of freedom [18]. For finite element analysis, the advanced ABAQUS software was used for our numerical simulation [2,[19][20][21][22]. The goal of our project is the design of beam models on two supports subjected to bending.…”

The influence of notch connection location on the short-term behaviour of timber-concrete composite beams, modelling of TCC beams and research for optimal locations, a numerical study

“…The concrete slab, the LVL beam, the OSB plate and the screw connectors were modelled using the 8-node linear brick element with reduced integration "C3D8R". The element has the potential to be used in a wide range of nonlinear analyses including plasticity, contact, large displacements, and failure [16]. The concrete reinforcement was modelled using the truss element T3D2, which is a linear element with two nodes.…”

Flexural behavior of delta and bi-delta cold-formed steel beams: experimental investigation and numerical analysis

“…inite element analysis provides a cost-effective solution to many engineering problems given the cost and time required to manufacture and create tests of actual physical models. This is why, in this article, a numerical study by finite elements is carried out using the Abaqus 6.14 software through a nonlinear structural analysis [21,22], the choice of the Abaqus software is thanks to these great performances in the numerical analysis, Finite element modeling goes through several steps starting with the creation of a geometric model of the structure, then the integration of the behavior of the material and the boundary conditions for each element which is then divided into smaller forms elements connected to specific nodes (the mesh) and analysis should be performed [4,15,[23][24][25][26][27][28][29].…”
