چکیده مقاله
This paper presents an investigation on the potential use of cold formed steel sections CFS sections in moment resisting frames MRFs for seismic applications The main limitation of CFS sections is the low out of plane stiffeners of their thin walled elements which leads to low ductility In earthquake resistant MRFs, the beams are designed to provide considerable ductility, whereas the other elements are mainly limited to their elastic range The proposed beam–column connections are used to connect innovative column which has box section and double back to back C shape beam In web bolted connections without out of plane stiffeners, premature web buckling results in early loss of strength, while some kinds of stiffeners can improve the performance of connections The behaviour of CFS beam–column connections is studied by means of finite element analysis FEA The results of the analyses show optimum stiffeners which can postpone local buckling, and they increase dramatically the level of resistant moment
