“…Manikandan and Thulasi [11]on investigating lipped channel stiffened at intermediate web revealed that the provision of intermediate web and edge stiffeners will improve the behaviour and increase the strength of the section. Muftah et al [12] investigated bolted built-up samples of two types as extended stiffener and outstand stiffener. Bolted built-up section with extended stiffener expressed a good outcome of flexural strength.…”

Abstract. Cold-formed steel, thin-walled steel product finds a wide application in construction worldwide. It has many advantages such as flexibility, convenient handling and fabrication and so on. The CFS is commonly used in structures like bridges, railway coaches etc., as it is economical when compared with hot-rolled steel. It can be used as single or built-up flexural members. Generally, the open section beams are susceptible to failure by lateral- torsional buckling due to the position of its centre of shear and centroid of the cross-section. To overcome this issue, open doubly-symmetric built-up sections or built-up closed sections have been used by many researchers. The parametric studies were conducted by many researchers to find the accuracy of the design strength predictions of the built-up beams. In parametric study, Eurocode specifications, the direct strength method and effective width method based on the North American specifications were used. The study reveals that there are no proper design guidelines available in the current Eurocode and North American specifications. Therefore, the paper provides an outline of research works done on various CFS sections by the researchers and their proposed design recommendations to the codal specifications were also reviewed.

In the construction of steel structures, the two most common types of structural members are hot-formed and cold-formed members. This paper mainly describes the analytical and experimental research on the strength and characteristics of CFS bolted built-up sigma sections having different structural arrangements under bending. The cross-sectional dimensions for the parametric study were selected by the sizes available in the market. In this paper, ANSYS workbench software was used to perform FE modeling and observe the local, flexural, and interaction of these buckling. Then, experimental study was performed by varying the arrangement of open section beams between face-to-face and back-to-back, connected using bolts or fasteners different spacings. Further, we conducted bending tests on cold-formed steel built-up members having simple edge stiffeners in the middle. Comparing both analytical and experimental studies, the results indicate that the back-to-back connected built-up beam section provides a flexural capacity higher than the face-to-face built-up section. Moreover, increasing the bolt spacing enhanced the load-carrying capacity of back-to-back sigma section built-up beams. It has also been discovered that the flexural strength of beams is primarily determined by bolt spacing or itsposition.

“…Muftah et al [3] reported the result of the behavior of built-up face-to-face CFS section with difference channel section which is fastened by using bolt and nut and known as outstand and extended stiffener under bending load. By producing the built-up section, the production cost of the section can be reduced and the cost of using an expert and high technology machine can be reduced.…”

The main objective of the study is to determine the behavior of built-up cold-formed steel (CFS) stub columns infilled with washed bottom ash (WBA) concrete and also their failure mode. Five proportions of WBA as sand replacement in concrete and five specimens of built-up CFS stub columns infilled with WBA are produced in this study. There are four parts of the testing conducted: material properties of CFS, material properties of WBA concrete, mechanical properties of the connection, and mechanical behavior of built-up CFS stub columns. The result shows that the specimen with 25% WBA is reported to have the highest value of compressive strength in the material properties of WBA concrete and the mechanical behavior of built-up CFS stub column. The percentage difference of the ultimate load of the built-up CFS column filled with normal concrete and filled with WBA concrete is noted to have a range of 3% to 25%.
