35 m Large Opening Roof Structural System Made of Hot Rolled and Cold Formed Steel Profiles

摘要

The paper presents some concept design stages of a roof steel structure of a building with a 35m wide opening. The main objective of the structural design is the quantitative and qualitative optimization of the structural elements. This objective generated the approach of several solutions of structural elements and their combinations. The structural solution was find to be a combination between Rectangular Hollow Section hot rolled profiles and Cold Formed Steel profiles that both have an efficient weight - stiffness ratio.
