- Abstract
A reinforced beam–column joint specific to mid-rise cold-formed steel (CFS) dwellings was proposed and studied by six full-scale cyclic loading tests. Afterwards, a moment–rotation relationship prediction model and a numerical model of the joint were established. The results show that: (i) the joint has a certain bending moment transmission capacity; (ii) the joint's moment–rotation curve has distinctive three-stage deformation characteristics, including elastic, nonlinear, and failure stages successively; the structural performance of the joint is better and more in line with the requirements of mid-rise CFS dwellings than conventional joint; (iii) the elastic buckling strength of beam flange can be taken as the elastic limit of the joint, and the ultimate bending moment of the joint is determined by elastic flexural capacity of beam section; (iv) the prediction model and the numerical model can be used to establish an overall model of mid-rise CFS dwelling with consideration of joints' nonlinear behaviour.
