Cold-Formed Steel (CFS) is a good construction material because of its high strength-to-weight ratio, that is, it exhibits efficient load carrying capabilities in combination with lightweight characteristics. Although CFS already being used construction, information on structural performance locally-produced the Philippines scarce. To date, authors have not found any experimental study done reg...

As the load increases, most composite beams generally experience failure in both shear and flexural behavior. This outcome highlights critical challenges of achieving sufficient strength structural integrity such beams. The proposed study has used cold-formed behavior an Enhanced C-channel (EC) connectors Light Weight Concrete (LWC) to examine new Steel-Lightweight Concrete-Steel sandwich Beams...

Lightweight cold-formed steel (CFS) framing is an effective building solution for low and mid-rise structures. However, systems level response and component contributions as well as their interactions such as those from lateral-load resisting systems, floor diaphragms, studs to track connections, etc., are not fully understood. Existing building codes for the CFS frame buildings are based solel...

The main objective of the study is to determine behavior built-up cold-formed steel (CFS) stub columns infilled with washed bottom ash (WBA) concrete and also their failure mode. Five proportions WBA as sand replacement in five specimens CFS are produced this study. There four parts testing conducted: material properties CFS, concrete, mechanical connection, columns. result shows that specimen ...

Powder-actuated (also referred to as low velocity or powder-driven) fasteners are commonly used to attach cold-formed steel framing members, usually a track, to a concrete or structural steel support. Although commonly used, their behavior is less well understood than other fasteners such as screws, bolts and welds. The AISI Cold-Formed Steel Design Manual does not explicitly address powder act...

The concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the...

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 assemblages at elevated temperatures; and complementary analysis and design methods necessary for the development of analysis-based design for cold-formed steel systems under fire. Cold-formed steel systems have become popular i...

The objective of the study is to determine flexural behavior built-up cold-formed steel (CFS) channel section strengthened with an oriented strand board (OSB) in three-point bending experiment. CFS a variety shapes and grades classified as steel-based material exposed buckling failure when subjected compression or load. Thus, 100 mm web, 50 flange, 12 lip, 1.55 thickness has been selected. Then...

Cold-formed steel structures represent a suitable alternative to classical, by now, structural solutions considering the recycling/reuse tendency worldwide as part of circular economy paradigm. The paper presents new design approach for CFS profile joints accurately predict their realistic behavior, based on experimental and numerical investigation two types connectors frequently used in constr...
