Buckling Coefficient of Partially Stiffened Elements of Cold-formed Steel Lipped Channel Section Under Axial Compression
摘要
Abstract
The elastic buckling stress of different sections for cold-formed thin-walled steel lipped channel axial members are predicted by finite strip program (CUFSM) and get the suggested calculation formula of plate buckling coefficient of partially stiffened elements according to regression analysis. The load-carrying capacities of 100 lipped chanel section compressive members collected are computed using ' Cold-formed steel structures (AS/NZS 4600; 2005)', 'Supplementary rules for cold-formed members and sheeting (EN1993-1-3; 2006)', 'North American specification for the design of cold-formed steel structural membersCAISI S100-2007)'. 'Specification for the design of cold-formed steel structural members (AISI 1996)', and 'Technical code of cold-formed thin-walled steel structures'(GB 50018-2002) and the suggested buckling coefficient. The calculated results show that 'Technical code of cold-formed thin-walled steel structures (GB 50018-2002)' and 'Supplementary rules for cold-formed members and sheeting (EN1993-l-3:2006)' are conservative and 'Cold-formed steel structures (AS/NZS 4600-2005)', 'North American specification for the design of cold-formed steel Structural Members (AISI S100-2007)' and 'Specification for the design of cold-formed steel structural members (AISI 1996)' are unsafe. The calculated results using suggested method are agree with test results.关键词
