The work presented in this paper investigates the strength of moment-resisiting apex brackets cold-formed steel portal frames. results two previously reported full-scale frame tests, where frames failed through buckling bracket, were used to validate a finite element model that included material nonlinearity, geometric imperfections, and bolt bearing behaviour. From test as well results, import...

Nowadays, due to environmental changes, the condition of buildings can be in danger. In order protect performance existing buildings, it is important investigate seismic behaviour building structure subjected earthquake excitation. addition, study advanced level ductile design recommended by current codes. immediate future, lateral load resistance needs evaluated precisely. For purpose analyzin...
