TL;DR: In this article, a numerical model is developed to study the behavior of slender concrete filled high strength steel columns incorporating material and geometric non-linearities, and the equilibrium of the member is investigated in the deformed state, using the idealised stress-strain relationships for both the steel and concrete materials, considering the elastic and plastic ranges.

TL;DR: In this paper, a series of tests were carried out on short and slender concrete-filled stainless steel tubular columns to explore their performance under axial compression or combined actions of axial force and bending moment.

TL;DR: In this paper, the mechanical properties of high strength structural steel and mild structural steel at elevated temperatures were investigated using steady and transient-state test methods, and it was shown that the reduction factors of yield strength and elastic modulus of both high strength and mild steel are quite similar for the temperature ranging from 22 to 540°C.

TL;DR: In this paper, the strength behavior of short columns under the combined actions of axial compression and bending moment has been investigated and a simple model for the determination of the strength interaction diagram is also verified against both the test results and the numerical model developed in this paper.

TL;DR: In this article, a nonlinear analysis and design of stiffened square stub columns under axial compression is performed using ABAQUS, a commercially available finite element (FE) program.
