Composite structural systems are those in which two or more materials act together to resolve the forces acting on a building. Steel–concrete composite construction solutions have been in use for decades, leveraging the differing properties of the two materials to achieve performance levels beyond what could be attained by using each material individually. Despite their superior structural efficiency, steel–concrete composite solutions were still considered a “niche” product in some regional markets, largely due to a lack of established best-practice information or expertise, low developer awareness of their benefits, and other challenges related to market positioning.
Through an academic and industry survey of the state of the art in steel–concrete composite structural systems, this research project produced an analysis of steel–concrete composite applications within the construction market.
A comprehensive scientific literature review and an analysis of international codes and standards were integrated and supported by the engagement of three expert panels composed of members of the AEC industry operating internationally. These panels comprised experts from CVU member companies as well as those appointed by Constructsteel members.
The combined outcome of these activities was the development of a research roadmap identifying the needs of composite construction and a categorization of available composite construction systems, intended to serve as a guide for practitioners and experts seeking to address knowledge gaps related to steel–concrete composite structural solutions.
CVU Expert Panels
Developers & Cost Consultants Expert Panel
Through case studies, this panel identified and analyzed structures using composite steel/concrete systems in order to gain insight into the costs, efficiencies, scheduling, and other factors that determine whether to pursue composite structural solutions.
Structural Engineers Expert Panel
The purpose of this panel was to gain a deeper understanding of the relationship between design aspects of steel/concrete composite systems, in the context of maximizing investment returns and minimizing project costs. Discussion items included the application of standard codes and software to steel/concrete composite systems, as well as other practical considerations.
Construction Companies Expert Panel
This panel investigated case studies from the perspective of construction practitioners, with panelists discussing the advantages and challenges of working with steel/concrete composite structural solutions during the planning and construction phases.
