The Wood Products Council 2011 LEARNING OBJECTIVES: AT THE END OF THIS PROGRAM, PARTICIPANTS WILL BE ABLE TO 1. Identifying the advantages and disadvantages of a variety of solid wood panel products. 2. Acquire current status of the joint Canada/US code committee work 3. Examine how solid wood panels are used in actual projects. 4. Discover real world applications of solid wood panel projects.

2 2007 World Passivhaus Conference What is a Passivhaus? Sustainability rating system like LEED, but focused solely on energy performance. Over 25,000 Passivhaus registered buildings in Europe. Building must use 15 kwh/m2 or less per year in heating energy. The building must not leak air at more than 0.6 house volume per hour (n / hour), when de-pressurized to 50 Pa below atmospheric pressure by a blower door apparatus. The total primary energy consumption (primary energy for heating, hot water and electricity) must not exceed 120 kwh/m² per year. Bregenz Austria

6 Sustainability Heat bridges Good thermal mass (double that of concrete by weight) Good R value lowers effects of heat bridges Air tightness Helps control interior humidity Renewable Sequesters CO 2 Structurally Construction Excellent strength to weight ratio (governed by vibration) Robust (durable and low maintenance) Shallow (10 to 15% shallower than concrete) 1/6 th of the weight of concrete (reduces foundation and seismic loads) High level of accuracy & reliability from shop fabrication Dimensionally stable Fast installation Economically compares well to concrete and steel construction Prefabrication reduces on-site trade demands mechano set Appropriate for remote sites Reduces M & E and finishes installation time (by ½?) Clean, dust free and quite site Accurate

7 Unique Structural Characteristics Rules of Thumb Light and rigid vibration often governs Rolling shear affects strength, deflection and creep I effective increases with span because of the cross laminations Bearing perp. to grain 30 to 50% higher Check punching shear Depth to span ratios: Floors Roofs Typical spans: Non composite - spans of 3 to 8m (10 to 26 feet) Composite spans of 6 to 12m (20 to 40 feet) Effective Stiffness increases for longer spans Seismically I effective depends on the span because X-layers alter stiffness I effective / I nominal: 100mm (4 ) CLT 3m (10ʼ) span = 85% 4m (13ʼ) span = 90% 170mm (7 ) CLT 3m (10ʼ) span = 70% 4m (13ʼ) span = 75% 6m (20ʼ) span = 80% Panels are very strong and rigid High shear capacity ( 4.0 MPa vs 5 MPa upper bound for RC) Ductility governed by connections Vertical (lap) joints in panels add to ductility Rd = 2.0; Ro = 1.5 recommended by FP Innovations in the Canadian handbook (equivalent to R = 3.75 and Ω = 2.0 T.B.C.)
