Abstract:
In order to study the ultimate load-carrying capacity of cold-formed thin-walled lipped channel members under eccentric compression, destructive experiments were conducted to investigate the behaviors of 13 specimens under eccentric compression. The specimens were simulated and analyzed by finite element analysis method. The well fitting between finite element analysis and test results proved the validity of the finite element method. Then large numbers of parametric analyses were carried out on typical members,the influences of section dimension, slenderness ratio,action point of load and material property for ultimate load-carrying capacity of cold-formed thin-walled lipped channel members under eccentric compression were studied. Strength-reduction method for ultimate load-carrying capacity of cold-formed thin-walled lipped channel members under eccentric compression and its corresponding calculator were proposed. Results show that the strength-reduction method proposed in the paper for calculating ultimate load-carrying capacity of cold-formed thin-walled lipped channel members under eccentric compression can be applied to practice.
