This presentation provides specific design guidance on how to address common scenariosin structural analysis and design for CLT. Attendees will learn about the necessary design checks for floor and roof applications including strength and short-term and long-term deflection checks under gravity loading, as well as detailed instructions on how to calculate the structural fire resistance ratings of horizontal CLT assemblies. Particular attention will be given to the engineering implications of using multi-span CLT panels and resulting modifications to the single span design conditions. Additionally, a detailed explanation of different methods of determining horizontal diaphragm deflections will be presented.  \nLearning Objectives  \n• Review the design methods and performance checks for CLT panels used in floor and roof applications and how to use these to show code compliance.  \n• Understand how to calculate the structural fire resistance rating of a CLT panel using the calculated method of AWC’s NDS Chapter 16.  \n• Discuss the types of structural analysis models which can be used in the design process and when they are needed.  \n• Review and understand calculation of horizontal diaphragm deflection of CLT floor and roofs  \nAgenda  \n• CLT Grades, Layups, Laminations, and Properties  \n• CLT Floor and Roof Analysis  \n• Structural Fire Design of CLT  \n• Design and Modeling Approaches of CLT  \nA collection of related topics answering real questions raised by designers.  \n\n| What is Cross-Laminated Timber? |  |  |\n| --- | --- | --- |\n| • IBC recognized structural component\u003Cbr>• Flat panel made from 3+ layers (AKA “plys”) of timber laminations\u003Cbr>• In alternating orientations –> “Cross-Laminated”\u003Cbr>• Assembled with specific structural adhesives |  | Thickness 3 to 20 inches |\n| | \u003Cbr>Max Length 16 to 80 feet\u003Cbr>Max Width 4 to 12 feet\u003Cbr>Consult with manufacturers’ info on sizes available |  |\n\n\n| North American CLT Product Standard |  |\n| --- | --- |\n| | The Standard Covers:\u003Cbr>- U.S. and Canada Use\u003Cbr>- Panel Dimensions and Tolerances\u003Cbr>- Component Requirements\u003Cbr>- Structural Performance Requirements\u003Cbr>- Panel and Manufacturing Qualification\u003Cbr>- Marking (Stamping)\u003Cbr>- Quality Assurance |\n| ANSI/APA PRG 320 Standard for Performance-Rated\u003Cbr>Cross-Laminated Timber |  |\n\n\n| Benefits of CLT |  |\n| --- | --- |\n| | Considerations:\u003Cbr>• Large light-weight panels\u003Cbr>• Dimensionally stable\u003Cbr>• Precise CNC machining available\u003Cbr>• Recognized by IBC\u003Cbr>• Dual Directional span capabilities\u003Cbr>• Often architecturally exposed\u003Cbr>• Fast on-si","cbCaieYqXAiehA46","https://ap.wps.com/l/cbCaieYqXAiehA46","pdf",6256482,112,"English","# Course Description\n## Learning Objectives\n## Agenda\n# What is Cross-Laminated Timber?\n## CLT Grades, Layups, Laminations, and Properties\n# North American CLT Product Standard\n# Benefits of CLT\n## Fabricated for Precise and Fast Construction\n# Strength Directions of CLT\n## CLT is an Orthotropic Material","[{\"question\":\"What structural design checks does the course cover for CLT floor and roof applications?\",\"answer\":\"The course covers required strength checks and short-term and long-term deflection checks under gravity loading for floor and roof use.\"},{\"question\":\"How is the structural fire resistance rating for a CLT panel determined?\",\"answer\":\"It explains how to calculate the structural fire resistance rating of a CLT panel using the calculated method referenced in AWC’s NDS Chapter 16.\"},{\"question\":\"Why are multi-span CLT panels important in the design process?\",\"answer\":\"The course highlights the engineering implications of using multi-span CLT panels and the modifications needed to address multi-span conditions compared to single-span design assumptions.\"}]","Structural Analysis and Design of Cross-Laminated Timber - AIA/CES continuing professional education course | PDF",282]
