Through changing the thickness of end-plate, bolts layout and rib stiffener of the node zone to analyze the influence of these parameters on bearing capacity of components and rigidity. Failure modes of portal frame were different from these of the normal steel frame in the analysis. The node zone shows the characteristics of semi-rigid connection. Some suggestions in the portal frame design are given.
