Description

Seat type

Seat attached to the support by

Design shear force V* (kN) Minimum design shear of min(40 kN, 0.15 φV_v) applied (AS 4100 9.1.4).

Clearance c (mm) - nominal; +4 mm under-run used in design

Restraint cleat (stability) ASI DG6 B3 / B4: the restraint cleat provides stability only (not designed for load) and is relatively thin. Web cleats need no allowance for the beam depth tolerance; top cleats use slotted holes, a loose angle or packers (Fig. B3).
