12 Parabolic Cable Tension and Length Calculators

Tension at Midspan given Tension at Supports for UDL on Parabolic Cable
Go Tension at Midspan = sqrt((Tension at Supports^2)-(((Uniformly Distributed Load*Cable Span)/2)^2))
UDL given Tension at Supports for UDL on Parabolic Cable
Go Uniformly Distributed Load = (sqrt((Tension at Supports^2)-(Tension at Midspan^2))*2)/Cable Span
Tension at Supports for UDL on Parabolic Cable
Go Tension at Supports = sqrt((Tension at Midspan^2)+(Uniformly Distributed Load*Cable Span/2)^2)
Span of Cable for Length of Cable for UDL on Parabolic Cable
Go Length of Cable Span = 1.5*Length of Cable-sqrt((2.25*Length of Cable^2)-8*(Maximum Sag^2))
Span of Cable given Tension at Supports for UDL on Parabolic Cable
Go Length of Cable Span = (sqrt((Tension at Supports^2)-(Midspan Tension^2))*2)/Total UDL
Span of Cable given Tension at Midspan for UDL on Parabolic Cable
Go Cable Span = sqrt(8*Tension at Midspan*Maximum Sag/Uniformly Distributed Load)
Parabolic Equation for Cable Slope
Go Y Co-ordinate = Uniformly Distributed Load*(Distance from Midpoint of Cable^2)/(2*Midspan Tension)
Maximum Sag given Length of Cable for UDL on Parabolic Cable
Go Maximum Sag = sqrt((Cable Length-Cable Span)*(3/8)*Cable Span)
Tension at Midspan for UDL on Parabolic Cable
Go Tension at Midspan = (Uniformly Distributed Load*(Cable Span^2))/(8*Maximum Sag)
Maximum Sag given Tension at Midspan for UDL on Parabolic Cable
Go Maximum Sag = Uniformly Distributed Load*(Cable Span^2)/(8*Tension at Midspan)
Length of Cable for UDL on Parabolic Cable
Go Cable Length = Cable Span+(8*(Maximum Sag^2)/(3*Cable Span))
Allowable Stress for Compression Elements for Highway Bridges
Go Allowable Stress = 0.44*Yield Strength of Steel

Allowable Stress for Compression Elements for Highway Bridges Formula

Allowable Stress = 0.44*Yield Strength of Steel
σallowable = 0.44*fy

What is Yield Strength of Steel?

Yield strength is the maximum stress that can be applied before it begins to change shape permanently. This is an approximation of the elastic limit of the steel. If stress is added to the metal but does not reach the yield point, it will return to its original shape after the stress is removed
