Rules of Thumb • CLT design has the ‘feel’ of concrete • Floor span-to-depth ratios 20-30 • Roof span-to-depth ratios 30-40 • Deflection and vibration control design(not strength) • Engineers must consider creep and rolling shear • Effective stiffness increases for longer spans Courtesy: Equilibrium Consulting Inc.
