State of research for shear connector performance in steel-CLT composite beams
The emergence of cross-laminated timber (CLT) as a sustainable construction material in the United States is opening commercial and industrial building stock to the timber industry, an area otherwise currently dominated by structural steel and reinforced concrete. CLT panels are limited in span, requiring the use of timber or steel beams and columns. This paper presents an in-depth review of existing research focused on shear connector performance with respect to composite beam action between CLT panels and structural steel beams. Numerous conclusions are presented alongside commonly indicated areas for future work resulting in a “state of research” for steel-CLT composites.
