Framing, Sheathing & Truss Systems
To remember the main framing elements: 'Silly Old Harry Can't Read The News' for Sill, OSB (sheathing), Header, Cripple, Rafter, Top plate, Nailing.
Wood Construction Methods
Framing, Sheathing & Truss Systems
The California Building Code (CBC) has specific requirements for seismic bracing and shear wall design, often requiring higher levels of fastening and specific sheathing panel layouts than in non-seismic regions. Pay attention to terms like 'shear wall' and 'hold-downs'.

Wood Construction Methods
Glued Laminated & Heavy Timber Construction
GLU-LAM: 'GLUed' layers make it 'LAMinated' and strong, like a super-sandwich of wood!
Wood Construction Methods
Glued Laminated & Heavy Timber Construction
The California Building Code (CBC) adopts the International Building Code (IBC) Type IV Heavy Timber classification, which specifies minimum nominal dimensions for structural members to achieve fire resistance. Memorize the general concept of these minimum sizes and their role in fire performance.
Wood Construction Methods
Glued Laminated & Heavy Timber Construction
Failing to protect glulam and heavy timber from moisture during storage and construction, leading to warping or fungal growth.
Wood Construction Methods
Glued Laminated & Heavy Timber Construction
Improperly designing or installing connections, which are critical for transferring loads and maintaining structural integrity.
Wood Construction Methods
Glued Laminated & Heavy Timber Construction
Underestimating the weight and size of members, leading to inadequate lifting equipment or unsafe handling practices on site.
