LOAD AND DEFLECTION TABLE – EXPANDED MESH

This table is theoretical and is based on uniformly distributed load of 100 kg/m 2 (1kPa)

Note: For uniformly distributed load other than 100kg/m 2(1kPa) mesh stress and deflection can be calculated using the factor shown in the following table

 

Stress and Deflection Factor

Uniform Load kg/m2 50 100 150 200
Factor (i) 0.5 1.0 1.5 2.0

S = Stress in kg / mm^2
D = Deflection in mm

Allowable Stress = 18 kg/mm^2 (180MPa)
Allowable Deflection = L(Span) / 300mmSample Calculation

 

Sample Calculation

Uniform Load : 200kg/m^2 (2kPa) → factor(i) of 2.0
Grating code: RG 50080   Span: 900mm
Stress(S) = 3.6 x 2.0 = 7.2kg/mm^2
Deflection(D) = 2.9 x 2 = 5.8mm
