Performance-based fire design for cold-formed steel systems is in its infancy. This paper
brings together existing research on cold-formed steel materials, members, and …

A new fire design method by Geometrically and Materially Nonlinear Analysis with
Imperfections (GMNIA) and using strain limits is proposed for stainless steel columns in this …

Cold-formed steel built-up box columns are commonly used in mid-rise cold-formed steel
buildings to resist applied loads. Numerous studies have been conducted to evaluate the …

This paper presents a study on the global buckling load of the cold-formed steel built-up box-
shape columns (CFS-BBC) at ambient and elevated temperatures. The energy method was …

The current design rules for cold-formed steel studs used in wall systems subject to non-
uniform elevated temperature distributions are complicated with iterations and different …

The aim of this paper is to report an ongoing shell finite element investigation on the
distortional post-buckling behaviour, ultimate strength and DSM design of cold-formed steel …

This study analyzes the behavior of steel columns reinforced by prestressed (PS) carbon
fiber reinforced polymer (CFRP) strips exposed to fire. First, tests are performed to study the …

CFS members are prone to geometric imperfections due to their slenderness, even if the
observed imperfections are minor. The main aims of this study are to gather imperfection …

This paper assesses the applicability of the Direct Strength Method (DSM) to calculating the
distortional buckling strength of cold-formed thin-walled (CF-TW) steel members with …

Experimental and numerical studies on the fire resistance of cold-formed steel (CFS)
columns with built-up box-shape sections were conducted in this paper. A series of coupon …
