Fixed-Fixed Beam with two UDL

Click For Summary
SUMMARY

The discussion focuses on calculating the maximum bending moment and maximum deflection of a fixed-fixed beam subjected to two uniformly distributed loads (UDL). The user initially attempted the double integration method but found discrepancies between their calculations and results obtained from ANSYS. A recommendation was made to utilize the singularity function method for a more straightforward solution to this problem.

PREREQUISITES
  • Understanding of fixed-fixed beam mechanics
  • Familiarity with uniformly distributed loads (UDL)
  • Proficiency in using ANSYS for structural analysis
  • Knowledge of singularity functions in beam deflection analysis
NEXT STEPS
  • Study the singularity function method for beam deflection calculations
  • Learn how to set up and analyze fixed-fixed beam models in ANSYS
  • Research the principles of maximum bending moment calculations for beams
  • Explore advanced techniques for solving beam deflection problems
USEFUL FOR

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

I'm looking for the max bending moment and max deflection of the beam shown in the problem statement. I tried using the double integration method to find the deflection, but it does not look right. I did the model in ANSYS to evaluate the solution, and the result does not match with my calculations.
If anyone could provide with a exact sample question with a detailed solution that would be great. Thanks a lot.
Sorry just could not get my head around for this question.

I would recommend using the singularity function method for something like this, otherwise it's quite arduous (as I'm sure you've noticed).
