Numerical and Experimental Investigations on the Behavior of Steel-reinforced Concrete Columns Subjected to Eccentric Loading

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...

Numerical Modeling of Steel-Composite Hybrid Tubes Subject to Static and Dynamic Loading

The commercial finite element program LS-DYNA was employed to evaluate the response and energy absorbing capacity of cylindrical metal tubes that are externally wrapped with composite. The effects of composite wall thickness, loading conditions and fiber ply orientation were examined. The results demonstrate that a wrapped composite can be utilized effectively to enhance the crushing characteri...

Cyclic Behavior of Cold-Formed Steel Stud-to-Sheathing Connections

This series of experiments aims to characterize the cyclic behavior of cold-formed steel (CFS) stud-to-sheathing connections. This connection provides the key energy dissipating behavior in wood sheathed CFS shear walls, and provides bracing to the studs under gravity and out-of-plane loads. A simple testing rig is developed consisting of two CFS lipped channels facing toe-to-toe connected on t...

Numerical Simulation of Ultra- Strength Concrete-filled Steel Columns

Article history: Received: 11. 09. 2013. Received in revised form: 01. 10. 2013. Accepted: 15. 10. 2013. Researches into the constitutive relation of the super high strength and high performance concrete and the stress strain relationship of the ultrastrength concrete-filled steel columns are rare. Therefore, this paper based on continuous mechanics presents the relationship of mathematical des...
