CLT Floor and Ceiling Calculations

Designing CLT floor, ceiling, and beam structures includes calculating allowable bending capacity (strength), shear capacity, deflection, and vibration and comparing those values to the design values of the material. The tool presented below assists engineers and architects to check their design in a few steps. The methodology is adopted from National Design Specification® (NDS) and CLT handbook: Cross-laminated Timber. You can select the CLT layup from the database of CLT manufacturers or enter custom values in the section below.
