This part of BS 5950 gives recommendations for:
—steel beams, columns and tension members designed to BS 5950-1;
—steel/concrete composite beams designed to BS 5950-3;
—concrete-filled steel hollow sections designed to BS 5400-5;
—composite floors designed to BS 5950-4.
For each type of member, recommendations are given for the load carrying capacity and, where appropriate insulation performance, for a given fire exposure assuming they act in isolation and restraint to thermal expansion is ignored.
These recommendations are based on:
a) fire resistance derived from standard fire tests;
b) fire resistance derived from calculations.
NOTE These recommendations may also be applied to members for which the fire exposure has been determined from natural fires.
