Abstract: A corner of a timber building frame (10) having spaced studs (11), top plates (12) and bottom plates (13). Bottom plates (13) are located in this case on an on-ground slab (14), noggings (15) retain the studs (11) in their proper spaced relation. To prevent the frames from moving in response to wind while the frame is under construction and also afterwards to resist movement in the event of earthquakes or high winds, bracing panels (16) comprise an elongated panel dimensioned for location between adjacent vertical studs (11) and between the top and bottom plates (12and (13), each panel has opposed ends (17 and 18) and opposed sides (19 and 20) and an intermediate portion between the sides shown generally at (21), the intermediate portion includes diamond shaped strengthening sections (22) displaced laterally out of the plane of the panel.
