What are Hybrid Bridge Girders ?

These may have flanges with larger yield strength than the web and may be composite or non-composite with a concrete slab, or they may utilize an orthotropic-plate deck as the top flange. Computation of bending stresses and allowable stresses is generally the same as that for girders with uniform yield strength.

How to Calculate Multiplier for allowable stress when flange bending stress does not exceed the allowable stress?

Multiplier for allowable stress when flange bending stress does not exceed the allowable stress calculator uses Allowable Stress Multiplier=1-((1-Ratio of web to flange yield strength)^2*(Ratio of web to flange area*Distance Ratio of flange to depth )*(3-Distance Ratio of flange to depth +Distance Ratio of flange to depth *Ratio of web to flange yield strength))/(6+Ratio of web to flange area*Distance Ratio of flange to depth *(3-Distance Ratio of flange to depth )) to calculate the Allowable Stress Multiplier, The Multiplier for allowable stress when flange bending stress does not exceed the allowable stress formula is defined as a factor used for allowable stress. Allowable Stress Multiplier and is denoted by R symbol.

How to calculate Multiplier for allowable stress when flange bending stress does not exceed the allowable stress using this online calculator? To use this online calculator for Multiplier for allowable stress when flange bending stress does not exceed the allowable stress, enter Ratio of web to flange yield strength (α), Ratio of web to flange area (β) and Distance Ratio of flange to depth (ψ) and hit the calculate button. Here is how the Multiplier for allowable stress when flange bending stress does not exceed the allowable stress calculation can be explained with given input values -> 1 = 1-((1-1)^2*(1*1)*(3-1+1*1))/(6+1*1*(3-1)).

FAQ

What is Multiplier for allowable stress when flange bending stress does not exceed the allowable stress?
The Multiplier for allowable stress when flange bending stress does not exceed the allowable stress formula is defined as a factor used for allowable stress and is represented as R=1-((1-α)^2*(β*ψ)*(3-ψ+ψ*α))/(6+β*ψ*(3-ψ)) or Allowable Stress Multiplier=1-((1-Ratio of web to flange yield strength)^2*(Ratio of web to flange area*Distance Ratio of flange to depth )*(3-Distance Ratio of flange to depth +Distance Ratio of flange to depth *Ratio of web to flange yield strength))/(6+Ratio of web to flange area*Distance Ratio of flange to depth *(3-Distance Ratio of flange to depth )). Ratio of web to flange yield strength is a strength ratio. , Ratio of web to flange area of orthotropic-plate bridge is the ratio of web area to area of tension flange or bottom flange of orthotropic-plate bridge and Distance Ratio of flange to depth is ratio of of distance from outer edge of tension flange or bottom flange of orthotropic deck to neutral axis divided by depth of steel section.
How to calculate Multiplier for allowable stress when flange bending stress does not exceed the allowable stress?
The Multiplier for allowable stress when flange bending stress does not exceed the allowable stress formula is defined as a factor used for allowable stress is calculated using Allowable Stress Multiplier=1-((1-Ratio of web to flange yield strength)^2*(Ratio of web to flange area*Distance Ratio of flange to depth )*(3-Distance Ratio of flange to depth +Distance Ratio of flange to depth *Ratio of web to flange yield strength))/(6+Ratio of web to flange area*Distance Ratio of flange to depth *(3-Distance Ratio of flange to depth )). To calculate Multiplier for allowable stress when flange bending stress does not exceed the allowable stress, you need Ratio of web to flange yield strength (α), Ratio of web to flange area (β) and Distance Ratio of flange to depth (ψ). With our tool, you need to enter the respective value for Ratio of web to flange yield strength, Ratio of web to flange area and Distance Ratio of flange to depth and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
