1 Project Code : T1 6 C1 Project Start Date (Month/Year) : 04 / 2010 Project Title : Influence of Manufacturing Parameters on CLT Plate to Resist Out-of-plane Loading Project Completion Date (Month/Year) : 03 / 2015 Revised Project Start Date (Month/Year) : Revised Project Completion Date (Month/Year) : Lead Investigator / Institution : Frank Lam / UBC University Co-Investigator(s) / Institution(s) : Terje Haukaas / UBC FPInnovations Co-Investigator(s) Ciprian Pirvu Industrial collaborator(s) / organization(s) : B. J. Yeh / APA HQP (code and name) : MSc4-T1 (Y1-2), MSc5-T1 (Y3-4), PhD3 T1 (Y3-5), PDF2-T1 (Y1-2) 1. Project progress (Provide a summary in point form of activities performed in the last period. If there is more than 1 student or PDF, provide a separate section for each.) Period 1: January 15 August 31, 2010 Initiated testing of shear strength and stiffness of glue bonds under different manufacturing conditions: species, pressure, adhesives Initiated development of FEM model for CLT plates Period 2: September 1 January 14, Completed testing of shear strength and stiffness of glue bonds under different manufacturing conditions: species, pressure, adhesives Progressing on development of FEM model for CLT plates Prepared for the NewBuilds workshop 2. Deviations from original research plan (If appropriate, provide a summary of any change in work plan and time line, with background and justification.) Year 2010 Original work plan Milestone/Deliverable Initiate development of experimental database on CLT plate including study of material properties and plate behavior. Year 1 Revised work plan* Milestone/Deliverabl e Page 1 of 3

2 Material properties to be investigated will include: the elastic and strength properties of the laminae (species, thickness, and grade) and fingerjoints; the elastic and strength properties of small CLT specimens produced under different manufacturing conditions including adhesives type, pressing parameters, panel construction details. Plate behavior will be studied by the evaluation of full size panels in bending under various support conditions. Completed the experimental database started in year 1 and develop a verified finite element model to predict the short term response of CLT plate under out-of-the-loading. Initiate development of experimental database and model on CLT strips under long term loading Complete experimental database on CLT strips under long term loading. Initiate verification of model Develop reliability analysis to quantify long term response of the CLT strips based on verified model Year 2 Year 3 Year 4 Year * Provide background for the revised work plan Justification for deviations from original work plan 3. Dissemination and implementation of research results (Provide a summary of presentations made, publications prepared and other impacts made as a result of the research.)
