【Abstract】 In this paper, the stability of the pitched portal frame is analysed and a current program ELPF is used to evaluate the critical axial force and the effective length of members in different types of pitched portal frames under arbitrary loadings. The parametric study is carried out and the relationship between the effective length of members and some structural parameters of the pitched portal frames with fixed or hinged supports is obtained. Tables for μ values of members of the pitched portal frames are also presented for practical purposes.更多还原
