Calculate the effective area of tensile strength of a tension member 180 × 65 × 8 mm. When it is connected by its I. longer II. Shorter leg to a gusset plate at either end using 20 mm ϕ rivets. Permissible tensile stress is 150 MPa.

Expert Solution

Step 1

Given:

Unequal angle section: 180 x 65 x 8 mm

A_g = 1896 mm²

Longer leg $x = 11.816 m m$

Shorter leg $x = 69.316 m m$

d_r = 20 mm

d_ro = 20+1.5=21.5 mm

P = 2.73 d_ro = 2.73 x 21.5 = 58.695 = 60 mm
