Post stressed frames and box beams glulam and lvl beams planks and floor systems. Clt sizing finished panels are typically 2 to 10 feet wide with lengths up to 60 feet and thickness up to 20 inches. To ensure an efficient design optimal panel spans and layout and the most cost effective structure. This method is suitable where a regular arrangement of cross walls can.
Notes calculations to generate the span tables are based on the shear analogy method as referenced in ansi apa prg 320. Floor and roof design the design of most clt floors will be governed by serviceability requirements typically deflection and vibration. Mb w l 2 8 40 40psf 16ft 2 8 2560 lb ft ft design example.
