Abstract

Abstract

As a modification of common H-section,a new type of lipped H-section member is proposed.As an economic benefit profile,it will be used as beams and columns in portal frames and purlines in roof.Since the local buckling load of the flange of lipped H-section is increased greatly due to the lip's reinforcement,the flange of lipped H-section,unlike common H section,will go out of the limit of width to thickness ratio.Based on elastic numerical results obtained by FEM,local buckling behavior was studied by changing geometric parameters of the section.Accordingly,the effective length to width ratio was determined,and a reasonable range of the lip's width coefficient and the flange width to thickness ratio were obtained.
- lipped H-section,
- lipped flange,
- local buckling,
- effective length to width ratio,
- lip's width coefficient,
- (flange's) width to thickness ratio
