Experimental and Analytical Investigation of Bolted Angle Joints for Cold - Formed Steel Double Channel Sections

Cold formed steel in light steel framing design can serve as alternative for industrialized building system , by extending steel work construction into residential housing. There is a lack in depth of study on the joints behavior of cold formed steel structures by assuming that beam-to-column joints are either pinned or rigid. These assumptions allow a great simplification in structural analysis and design, but unfortunately the true behavior of the joints being neglected.. In steel structures, moment resisting steel frames are highly regarded for their seismic performance. This regard is based on their ductility and inelastic performance, since inelastic deformation is used to dissipate energy during major earthquakes. This dissipation of energy is predominantly required in the connections like beam column joints. This is carried out with the influence of stiffener. Such a study of the inelastic behavior of steel connections would help in an economical and simpler design of connections in steel frames. This project develops a three dimensional finite element model using ANSYS and the results are compared with the experimental results.
