Wood is the most popular building material for residential homes and other smaller buildings. There are many types of wood products on the market used in the construction industry today. Some of the engineered wood products include I-joists, laminated veneer and glued laminated timber. However, the most familiar and well used is still sawn lumber. This course will provide the methodology for determining the allowable design values to use when designing sawn lumber components, such as beams, headers, trusses, floor joists, decking, etc. However, much of the same methodology and adjustment factors are also applicable to the other types of engineered lumber.
Safe design of wood components, such as beams, headers, floor joists, etc. requires the proper determination of design values. Reference design values that are listed among many sources need to be adjusted either upwards or downwards depending on the intended service, loading and support conditions of the wood. This course provides prescriptive guidance on how to determine allowable design values for wood.
This course demonstrates how to adjust the reference design values for the most significant factors. Methods for determining all the significant types of design values for wood will be taught which include bending, shear, compression (parallel & perpendic).
