Finite Element Modeling of Concrete-Filled Steel Tubes: Review and Recent Developments

Abstract:

The paper reviews previous investigations in the area of finite-element modeling of concrete-filled steel tubes. The literature provides a summary of the main type of the elements that are most frequently used to simulate concrete, steel and the interaction between the steel and the concrete in the composite beam and column members. A summary of confined concrete models is presented. Finally, finite-element were developed for 12 triangular concrete filled fabricated VHS-plate stub column specimens tested and reported in previous research [1, 2]. The confined concrete models, reviewed in the literature, were employed in the simulation and comparison was made to find the most suitable model for this type of column.
