Allowable Strength Design Load combination (eq8)
In structural engineering, a structure is a body or combination of pieces of rigid bodies in space to form a fitness system for supporting loads. Structures such as buildings, bridges, aircraft and ships are all examples under steel structure. The effects of loads on structures are determined through structural analysis. Steel structure is steel construction material, a profile, formed with a specific shape or cross section and certain standards of chemical composition and mechanical properties.
There are currently two common methods of steel design: The first method is the Allowable Strength Design (ASD) method. The second is the Load and Resistance Factor Design (LRFD) method. Both use a strength, or ultimate level design approach.
We are presenting here an equation of the Allowable Strength Design (ASD) method.
The shown fomrula is for 0.6 times dead load plus or minus 0.7 times earthquake load.
Notice that the earthquake load can be added or substitute din the equation. However, in the shown fomrula it’s being added.Related formulas
