1.7-3 The upper deck of a football stadium is supported by braces, each of which transfers a load P = 700 kN to the base of a column (see figure part a). A cap plate at the bottom of the brace distributes the load P to four flange plates (†ƒ = 25 mm) through a pin (d = 50 mm) to two gus- set plates (tg 38 mm) (see figure parts b and c). Determine the following quantities. = (a) The average shear stress Taver in the pin. (b) The average bearing stress between the flange plates and the pin (f), and also between the gusset plates and the pin (bg). (Disregard friction between the plates.)

Beams

In structural engineering, a beam is a component made of a variety of materials (including steel alloys, and wood) that can resist loads applied laterally to the beam axis. Members, elements, rafters, shafts, and purlins are all terms used to describe beams.

bottom of the brace distributes the load P to four flange
plates (t = 25 mm) through a pin (d = 50 mm) to two gus-
set plates (t = 38 mm) (see figure parts b and c).
Determine the following quantities.
