Epoxy resin of the adhesives consist of structural adhesive and no structural adhesive. The one of structural adhesive is the S-CFN epoxy resin. Adhesive bonding is an effective method of joining many materials. In the other hand, welds, bolts, screws, rivets, and other mechanical fasteners are generally used for cold-formed steel joints. The AISI Specification contains only the design provisions for welded connections, bolted connections, and screw connections. The adhesive joint provides a more uniform stress distribution along the bonded area, which enables to have a higher stiffness and load transmission, reducing the weight and thus the cost. Adhesives can bond dissimilar materials in a thin joint efficiently. In this paper, the one of new connections method due to flexure loading on the cold-formed steel in civil engineering structures has been investigated. A research of new joints method due to flexure load on the cold-formed steel has been investigated. The Joint failure was modeled using finite element analysis (FEM) with a cohesive zone model (CZM) approach where the governing parameters were determined from fracture mechanics test specimens. Under middle uniform bending, the S-CFN joint undergoes an elastic stage first, then followed by a plasticity behavior accompanied by the formation of a number of micro cracks on the elements. Using a displacement control of 0.55â mm, the reaction force of beam is 6550 N. Using a displacement control of 0.55â mm, the maximum Von Mises stress (S11) of the S-CFN joint beam is 840â MPa. The types of stress distribution for yield moment based on different locations of the neutral axis. For balanced sections, a part of elements in the top and bottom flanges reach the yield point at the same time. The stress distribution at the S-CFN joint follows the behavior of the damage distribution. The strength capacity of cold-formed steel beam was successfully predicted. The modeling results have a good correlation with the experimental works. Strength capacity deviation of experimental work to FEM is 10.45 % © 2023 Author(s).
