Post + Panel: Next Generation Point Supported CLT Floors
Publication: Structures Congress 2023
ABSTRACT
This study provides an overview of the ongoing Post + Panel research program on point-supported cross-laminated timber (CLT) floors. Recent studies on rolling shear and punching shear have found that the capacity of CLT in shear may be higher than those specified in the standards. However, while there is a compelling case for higher point supported strengths, most tests have been completed outside of North America, and limited tests have been completed on point supported CLT panels. The work presented herein addresses this critical research need and consists of CLT rolling shear testing, CLT punching shear testing, and full-scale point-supported CLT floor testing. Rolling shear values are based on both short- and long-term testing including testing using both bend and inclined tests. Rolling shear strength amplification factors and typical stress distributions around columns are presented from previous research in various column configurations. The rolling shear strength was determined for CLT with lamellas of different species, grades, and aspect ratios. The results show that the mean rolling shear strength of CLT was between 0.9 and 1.8 MPa.
