a short wood framed member built on top of the foundation to support the first floor level

• Large area of sheathing (floor, roof, shear wall - could be vertical or horizontal)
• EDGES MUST HAVE BOUNDARY MEMBERS and the sheathing panels must connect to these members and to framing members to transfer forces across the panel joints

two horizontal framing members at the top of a wall, typicaly spliced or lapped to give continuity or tie wall sections together

essentially the same as a collector- connects a diaphragm to a shear wall

same as DRAG STRUT/COLLECTOR

though it could also mean a member that transmits force from one part of the structure to the other without collecting any force along the way

• shear panels 4 egdes
• 2 are ends
• 2 are sides
