This seminar explores the emerging hybrid construction method combining mass timber and cold-formed steel (CFS) to optimize structural performance and cost-effectiveness. We will examine structural, fire, and acoustic performance benefits, prefabrication advantages, and construction efficiencies. The presentation will also feature a detailed case study of the Bunker Hill Housing Redevelopment project in Boston, MA, showcasing a groundbreaking application of mass timber-CFS hybrid construction in an urban setting. Participants will gain insights into the design considerations, construction sequencing, benefits, and challenges associated with this hybrid structural system.
Learning Objectives
- Assess the structural efficiency, fire safety, acoustic performance, and sustainability advantages of integrating cross-laminated timber (CLT) and cold-formed steel (CFS) in mid-rise buildings.
- Examine how the thermal performance of mass timber and cold-formed steel contributes to energy-efficient building envelopes and reduces operational carbon.
- Compare the cost-effectiveness of CLT-CFS hybrid construction with conventional building systems, focusing on material efficiency, labor savings, and lifecycle costs.
- Explain the gravity and lateral load-resisting strategies of mass timber and CFS hybrid systems, including platform-type construction and connection detailing.
