NUMERICAL MODELING OF CONCRETE COMPOSITE STEEL TUBES

Numerical Analysis of Concrete-Filled Circular Steel Tubes

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...

Effect of the Concrete Strength on the Concrete-Steel Bond in Concrete Filled Steel Tubes

In this study, the concrete-steel bond strength of concrete filled cylindrical steel tubes has been experimentally investigated. 22 short, high strength and normal concrete filled circular steel tubes were tested. Push-out test was carried out as the common method to evaluate the bond carrying capacity. Four different concrete mixes were used in preparing the specimens. The steel tubes were w...

Steel Concrete Composite Structures: State of Art

The aim of this review article is to examine solutions and challenges associated with composite construction. Structural steel and concrete, each of the two materials can be used to its best advantage and, therefore, composite structures have proved economical in terms of overall cost. Combination of steel and concrete systems has been conceived on the premises that each type of construction of...

Analytical and numerical modeling of erosive projectiles into steel fiber reinforced concrete target

In this paper, modeling of high speed projectiles with different nose shapes, penetrating into steel fiber reinforced concrete is investigated. This is a novel study because it considers the length to diameter ratio of steel fiber as well as projectile length to diameter ratio and volume fraction of fiber used in concrete matrix on the impact resistance of steel fiber reinforced concrete fibers...
