Flange thickness of monorail beam
public
Determine minimum flange thickness of monorail beam as per AS 1418.18:2001 Section 5.12.3.1
Input
Load position factor
$ K_L = 1 \; \; $
Distance between wheel load flange edge
$ C_F = 96.5 \; \; mm $
Wheel load
$ N_W = 30 \; \; kN $
Distance between web and flange edge
$ B_F = 125 \; \; mm $
Yield stress of beam material
$ f_y = 300 \; \; MPa $
Longitudinal bending stress in the beam
$ f_b = 0 \; \; MPa $
Result
Minimum flange thickness
$$ T_{f_{AS1418}} = {K_L \cdot \sqrt{ {\left({ \left({ 2400 \cdot {C_F \over B_F} + 600 }\right) \cdot N_W }\right) \over \left({ f_y - 1.1 \cdot f_b }\right)} }} \; \; , {mm} $$
