An Investigation on Member Proportioning and Elasto-plastic Buckling Strength of Members for Single Layer Cylindrical Latticed Roofs

Abstract

This paper presents a proportioning method for members of single layer cylindrical latticed roofs considering shell-like buckling. The present method is applicable for proportioning members of not only roofs of short span but also roofs of long span, because the method defines both the elasto-plastic buckling strength of longitudinal members and that of diagonal members, respectively. This paper discusses also the effectiveness of the proportioning method by comparing the load carrying capacity of roofs designed using the presented proportioning method with the load for design.
