An experimental study on sheathed cold-formed steel C-lipped columns (studs) with service holes in the web subjected to compression and major axis bending is presented this paper. A total of 17 experiments was performed both oriented strand board (OSB) plasterboard used as sheathing material varying connector spacing employed between members. Material tests geometric imperfection measurements w...

This paper describes an experimental program which examined the flexural strengthening of timber beams (50x50x1000 mm) using cold-formed steel (CFS) plates (0.75 mm thick and 30 wide). A total fifteen specimens were tested in three-point bending scheme with a span-depth ratio 18:1. The effectiveness was evaluated for different lengths number layers. Test results showed that maximum load carryin...

Unprotected steel and structures exposed to the atmosphere inevitably corrode. For thin-gauged especially, corrosion is critical for stability. Although reduction in thickness caused by insignificant some structures, other unacceptable. Therefore, protection a crucial issue industry. Over last decades, many new systems innovative products have been introduced onto market. Corrosion cold-formed ...

The objective of this paper is to provide work towards design methods to predict both the loss of stiffness and the available ductility for cold-formed steel members subject to cross-section deformations resulting from local and distortional buckling. Existing design specifications provide some guidance on how to predict the stiffness of cold-formed steel members, but no guidance on their avail...

The North American construction industry has seen substantial growth in the use of cold-formed steel (CFS) framing for midrise buildings recent years. In seismic zones, CFS-framed utilize shear walls to provide primary lateral resistance earthquake induced loads. Although oriented strand board (OSB) and plywood panels have been traditionally used as sheathing material these essential components...

Staggered rectangular perforations (slots) are provided in the webs of cold-formed steel (CFS) beams and columns to reduce their thermal conductivity improve energy efficiency CFS buildings. The adversely affect structural characteristics members, especially those governed by web parameters, such as shear strength buckling. This paper presents machine learning (ML) models predict elastic buckli...
