Abstract:
1. A method of producing a thin wall profile member, comprising the steps of: providing a thin wall profile member having a cross section including at least one of (1) at least two main strips and at least one additional strip having ends connecting with respective ends of two of said main strips, and selecting cross section dimensions such that said main strip has a thickness δ selecting range values of cross section dimensions ratios for the thin wall profile member and various ratio values within the range values; determining for the thin wall profile member a plurality of shape efficiency factor values Σ where: finding within the plurality of the shape efficiency factor values Σ ascertaining the ratio values for the thin wall profile member which resulted in the maximum shape efficiency factor value Σ producing the thin wall profile member with the ratio values which resulted in the maximum shape efficiency factor value Σ
