- Abstract:
- The steel-concrete composite beams are increasingly used in bridge and building construction in recent years. A shear connection between the steel and concrete should be provided to effectively transfer the shear force and to make the two materials act as a single unit. The mechanical shear connectors provide this means. They are the essential component of any composite beam system. Many studies have been performed on shear connectors and many different steel shapes have been suggested for connectors. The steel studs and channels are the most popular code accepted connectors. However, economic considerations continue to motivate the development of new products.
Present knowledge of the capacity and behavior of the shear connectors are mainly limited to the data obtained from the push-out or beam tests with the latter being more expensive and accurate. Therefore, analytical when the experimental resources are not available.
In this study a three-dimensional procedures that can predict the nonlinear response and the capacity of the composite beams are necessary finite element model is developed to simulate the push-out test of angle shear connectors. The main objective of this study is to investigate the behavior and capacity of angle shear connectors in a solid slab.
The results of the finite element model are compared with results of the available tests. The Parametric studies are performed to investigate the effects of variations in angle dimensions and concrete strength. An equation is proposed in order to improve the capability of angle connector. Finally, an equation is proposed to predict the ultimate shear strength of the angle connectors - Keywords:
