Calculation of deflection for cross laminated timber floor panel

Abstract

In this paper analytically calculated values of effective flexural stiffness and deflections of five-layer CLT panels height 14 cm due to the payload defined in Eurocode 1 for floors in residential buildings are compared. Effective flexural stiffness was calculated using Gamma method, K-method and Kreuzinger's analogy. Three floor panels with identical height but with different combinations of lamination thicknesses in cross-layers were analyzed. The panels are 4.5 meters long and 1 meter wide. Lamination thicknesses in cross-sections of panels are 3􀀀3,4 cm+2􀀀1,9 cm, then 3􀀀3 cm+2􀀀2,5 cm and 5􀀀2,8 cm.
