BS 5950:<br />

Problem 1 Part 1<br />

Design a single angle tie for the member AB shown.<br />

Tensile force in member AB<br />

Dead load = 122 kN<br />

Imposed load = 220kN<br />

Total = 342kN<br />

Material: Use <strong>Steel</strong> Grade S355<br />

Connections: a) Welded<br />

b) Bolted<br />

Factored load<br />

Table 2<br />

Material <strong>Steel</strong> Grade S355, thickness £ 16 mm Table 9<br />

Design strength py = 355 N/mm2 F = ( 1. 4 ¥ 122)+ ( 1. 6 ¥ 220) = 523 kN<br />

a) Welded connections<br />

Try 125 ¥ 75 ¥ 10 connected by long leg. Code allows angle section with<br />

eccentric loading to be treated with a reduced tension capacity as given<br />

in Clause 4.6.3. 4.6.2<br />
