NCCI: Initial Design of non Composite Beams
General
This document provides design graphs for the selection of Universal Beam profiles to be used as secondary beams (non composite beams). These graphs give the maximum span length versus the slab span, for various section ranges and steel grades. The lightest section is used for each range.
Design graphs graphs are provided provided to help the designer designer in the the selection selection of rolled I-section profiles for secondary secondary non-composit non-compositee beams.

Two cases are considered for the serviceability limit state check (ref to UK industry guidance, as quoted in SN034 SN034): ):
Imposed load deflection limited to L/200 (for beams generally)
Imposed load deflection limited to L/360 (for brittle finishes)

The loads are uniformly distributed.
The weight of the slab is 3,0 kN/m .

The imposed load is 5 kN/m .
The bending resistance is based on the plastic moment resistance (Class 1 or 2) using the nominal yield strength of the material without taking into account any reduction related to the thickness.
Partial factors are: J G = 1,35, J Q = 1,50, J M0 = 1,0 and J M1 = 1,0.
The permanent loads are not taken into account for the serviceability limit state check.
