Mass timber panels including cross laminated timber (CLT) have the ability to span in 2-directions, using structural properties obtained in both the major and minor panel axes. Doing so can result in a beamless system often referred to as Post and Plate (a framing configuration also used in flat plate concrete construction). Vertical columns support the floor and roof panels at discrete locations. On the other hand, mass timber horizontal panels can span one direction, supported on a series of beams and then columns. So which system is the best for mass timber? Check out this video for comparisons of each, and some project types where each of these systems could work well.
