Abstract

Elastic supporting bars exist in many structures, like transmission tower, truss, even frame, etc. Take transmission tower for example, the load-carrying capacity of diagonal members often controls the structure’s bearing capacity. Previous experiments and engineering experiences indicated that possible unsafety exists in structures when designing diagonal members according to current codes. Based on the Timoshenko elastic stability theory, the study deduces the relations between adjacent web member’s internal force and stability capacity of X-shape diagonal members and K-shape ones. The calculation formula for diagonal member’s effective length factor of transmission tower was obtained, which can be reference in revising the codes.
