چکیده
In this paper the behaviour of steel frames is investigated under an applicable range of initial rotational geometric imperfection in joints, which are mostly created during the manufacturing process. A nonlinear analysis is applied in both geometry and material behaviour of steel frames. The results show considerable reduction in buckling and ultimate load carrying capacity of portal frames, when they are affected by a rotational imperfection
