Experimental and Numerical Study on Bar-Reinforced Concrete Filled Steel Tubular Columns Under Axial Compression
The behaviors of bar-reinforced concrete filled steel tubular columns subjected to axial load were studied. One plain concrete filled steel tubular column and three bar-reinforced concrete filled steel tubular columns were tested. The deformation of specimens and the strain of steel tubes were measured. Based on experimental researches, a simple numerical analysis method was presented to simula...
متن کاملNumerical 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...
متن کاملFire behavior of axially loaded slender high strength concrete - filled tubular columns
This paper describes sixteen fire tests conducted on slender circular hollow section columns filled with normal and high strength concrete, subjected to concentric axial loads. The test parameters were the nominal strength of concrete (30 and 80 MPa), the infilling type (plain concrete, reinforced concrete and steel fiber reinforced concrete) and the axial load level (20% and 40%). The columns ...
متن کاملMechanical Behavior of Recycled Aggregate Concrete-Filled Steel Tubular Columns before and after Fire
Recycled aggregate concrete (RAC) is an environmentally friendly building material. This paper investigates the mechanical behavior of recycled aggregate concrete filled steel tube (RACFST) columns exposed to fire. Two groups of 12 columns were designed and tested, under axial compression, before and after fire, to evaluate the degradation of bearing capacity due to fire exposure. Six specimens...
متن کاملCyclic Evolution of Damage and Beam-column Interaction Strength of Concrete-filled Steel Tube Beam-columns
The assessment of response of composite seismic force resisting systems requires accurate nonlinear formulations for the composite members. In this work, reporting the first phase of a NEES project, a three-dimensional distributed plasticity formulation is presented for both circular and rectangular composite concrete-filled steel tubes (CFTs) that includes new constitutive models for the concr...
