Deflection of a box section beam

Click For Summary
SUMMARY

The discussion focuses on calculating the deflection of a box section beam under specific loads. Craig seeks assistance in determining the deflection values for a mass of 19,000 kg and 10,000 kg using the formula Force = mass × acceleration (where acceleration is 9.81 m/s²). Participants emphasize the importance of correctly applying the deflection formula and ensuring unit consistency in calculations.

PREREQUISITES
  • Understanding of structural mechanics principles
  • Familiarity with deflection formulas for beams
  • Knowledge of unit conversions in physics
  • Basic proficiency in using mathematical equations for engineering calculations
NEXT STEPS
  • Research beam deflection formulas, specifically for box section beams
  • Learn about the impact of load types on beam deflection
  • Study unit conversion techniques in engineering calculations
  • Explore software tools for structural analysis, such as SAP2000 or ANSYS
USEFUL FOR

Structural engineers, civil engineering students, and professionals involved in beam design and analysis will benefit from this discussion.

Hi Guys,

Please see attached diagram.

I have done the maths but i am not convinced. Maybe i have missed something but i have not done structural maths for a while.

I am using Force = ma where m= mass and a = 9.81m/s2

I need a deflection value for a mass of 19000kg

And a mass for 10000kg


If anyone could help me out on this it would be much appreciated!

Thanks a lot

Craig

Yes, calculate the force (weight) as you have done and just calculate and plug in the given values into your equation for deflection. Just be sure to watch your units.
