Proper design of wood structures to resist high wind loads requires the correct use of wind load provisions and member design properties. A thorough understanding of the interaction between wind loads and material properties is important in the design process. Adjustments from reference wind conditions to extreme-value peak gusts require designers to make similar adjustments to design properties to ensure equivalent and economic designs. Wind load provisions have been developed for design of major structural elements using Main Wind-Force Resisting System (MWFRS) loads and secondary cladding elements using Component & Cladding (C&C) loads. Elements and subassemblies which receive loads both directly and as part of the main wind force resisting system, such as wall studs, must be checked independently for MWFRS loads and C&C loads. A load bearing stud wall design example based on the allowable stress design methods outlined in AWC's 2018 National Design Specification® (NDS®) for Wood Construction and 2018 Wood Frame Construction Manual along with ASCE 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures will demonstrate standard design checks for limit states of strength and deflection.
- Understand how to analyze wall framing as part of the MWFRS per ASCE 7-16
- Understand why wall framing is analyzed using out of plane C&C wind pressures independent of gravity loads
- Be familiar with various ASCE 7-16 ASD load combinations used for bearing walls
- Be knowledgeable of standards including the 2018 NDS, 2018 WFCM, and ASCE 7-16 used for design of tall walls

Please note a single registration allows you to have one connection. However, a number of people can view and listen to the seminar using one connection by using an LCD projector (or a large computer monitor) and good computer speakers or a speaker phone.
All attendees, irrespective of the number of registered connections, can earn 0.2 Continuing Education Units (CEUs) or 2.0 professional development hours (PDHs). CEU/PDH certificates are provided free of charge.
- A connection is defined as a single web connection plus a single telephone connection (if necessary). If you want to sign up for more than one connection for this seminar, you will have the opportunity to do so after placing the seminar in your cart.
- A $15 fee will apply if the seminar registrant wishes to revise the web seminar registration (e.g. switch from one web seminar to another).
- Refunds are limited to 80 percent of fee and must be applied for in writing WITHIN THIRTY DAYS after the scheduled seminar.
