SUMMARY

This discussion focuses on the sizing of structural beams, specifically for applications involving significant spans and loads, such as a 100-foot span supporting 100 tons at the center. Key factors influencing beam selection include material strength, beam height, thickness, and weight. The user seeks mathematical relationships and formulas to determine the torque and weight capacity of a ten-foot, 10"x10" solid square cantilever made of 50 KSI steel. A recommended resource for further information is Roark's Formulas for Stress and Strain.

PREREQUISITES
  • Understanding of structural engineering principles
  • Familiarity with material properties, specifically 50 KSI steel
  • Knowledge of beam mechanics and load calculations

General Questions About "sizing" Structural Beams.

Hello Guys. I would like to know where I can find high quality info on which types of beams to use for certain applications. Say, for example, a 100 foot span which is supposed to hold 100 tons at the center, or cantilever, and so on. I know there are many factors, such as material strength, "height" of beam, thickness of material, and weight of material, and the like, but I cannot figure out a mathematical relationship even for simple shapes, for I am no savant. For example, is there a way to mathematically deduce how much "torque", or "weight" a ten foot 10"x10" solid square cantilever of 50 KSI steel can handle before permanently deforming?
I am assuming these things have been figured out experimentally. Ultimately, I am asking you guys for guidance in terms of recommended sources (internet, and books) for such information, and formulas.

Thank you.
