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...

Fire 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 ...

Ambient and fire behaviour of eccentrically loaded elliptical slender concrete-filled tubular columns

This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete filled tubular columns with elliptical cross-section, the main objective of this paper is to compare the behaviour of such innovative cross-sections under ambient and high te...

Mechanical 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...

Inelastic Behavior of Concrete-filled Thin-walled Steel Tubular Columns Subjected to Local Buckling

This paper is concerned with the inelastic behavior of axially loaded concrete-filled thin-walled steel tubular columns subjected to local buckling. A nonlinear fiber element analysis program accounting for local buckling effects is developed for predicting the ultimate strength and ductility of concrete-filled thin-walled steel tubular columns. The effects of local buckling are taken into cons...
