One-bay and two-bay semi-rigid portal frames with crane are analyzed with finite element method, and the effects of connection's flexibility and members' geometrlc nonlinearity are considered. Internal forces and deformations of portal frame with different rotational stiffness are discussed. Design method are presented in design practice.
Keywords:  semi-rigid; end-plate connection; portal frame; internal force; displacement
