Flexural Behavior of Built-Up Cold-formed Steel Channel Section Strengthened with Oriented Strand Board

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, designed by filling OSB between gap each section. Channel, face-to-face built-up, back-to-back sections are three types tested specimens. From result discussion, specimen recognized sustain ultimate load highest value compared other
