Define Carbon Steel
Carbon steel is a steel with carbon content from about 0.05-2.1% by weight. The American Iron and Steel Institute (AISI) states:
- no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect,
- the specified minimum for copper does not exceed 0.40%,
- or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65%, silicon 0.60%; copper 0.60%
How to Calculate Allowable Unit Load for Bridges using Structural Carbon Steel?
Allowable Unit Load for Bridges using Structural Carbon Steel calculator uses Allowable Load = (Yield Point of Material/Factor of Safety for Bridge Column)/(1+(0.25*sec(0.375*Critical Slenderness Ratio)*sqrt((Factor of Safety for Bridge Column*Total Allowable Load for Bridges)/(Modulus of Elasticity of Material*Section Area of Column))))*Section Area of Column to calculate the Allowable Load, The Allowable Unit Load for Bridges using Structural Carbon Steel formula is defined as the load that induces the maximum permissible unit stress at a critical section of a structural member when the factor of safety and modulus of elasticity are predetermined. Allowable Load is denoted by Q symbol.
How to calculate Allowable Unit Load for Bridges using Structural Carbon Steel using this online calculator? To use this online calculator for Allowable Unit Load for Bridges using Structural Carbon Steel, enter Yield Point of Material (Sy), Factor of Safety for Bridge Column (fs), Critical Slenderness Ratio (L|r), Total Allowable Load for Bridges (P), Modulus of Elasticity of Material (ε) & Section Area of Column (A) and hit the calculate button. Here is how the Allowable Unit Load for Bridges using Structural Carbon Steel calculation can be explained with given input values -> 1305.263 = (220632233.379338/3)/(1+(0.25*sec(0.375*140)*sqrt((3*10500)/(199947961500.025*0.0522579600004181))))*0.0522579600004181.
