New structural solution of light-weight steel frame system, based on the sigma profiles

摘要

This paper presents a light-weight steel frame system with a span ranging from 6,0 m to 18,0 m and hight ranging from 3,5 m to 6,5 m, which is fully designed and produced in Poland. All structural elements of the frame are made from thin wall cross section ,,Sigma". Sandwich plates are used as light sheeting of the frame. The main structural elements are made from combined profiles and have a very effective cross section. The system frames with rigid joints are available in two versions, i.e. with or without bowstring. All joints of the structure are universal solutions which fit easily for every kind of system frame. The paper provides examples of a new joint solution and methods of calculation. It also presents a comparison of our own structural solutions with the well-known system ,,PRACTA".
