Calculating the vertical reaction and moment of a beam.

Click For Summary
SUMMARY

This discussion focuses on calculating the vertical reactions and moments at points A and B for a 4x4 beam that is 12 feet long, supported by 4x4 columns that are 8 feet tall. The point load, positioned in the middle of the beam, is specified as 10,000 kN. Participants emphasize the importance of understanding the material of the beams, suggesting that they could be either solid wood or structural steel, and discuss the implications of using beam hangers and fixation points in the calculations.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Familiarity with beam mechanics and load distribution
  • Knowledge of structural materials, specifically wood and steel
  • Experience with calculating moments and reactions in beams
NEXT STEPS
  • Research "Calculating vertical reactions in beams" using specific examples
  • Learn about "Moment distribution method" for beam analysis
  • Explore "Beam hanger design and specifications" for load-bearing considerations
  • Investigate "Material properties of wood vs. structural steel" for structural applications
USEFUL FOR

Civil engineers, structural designers, and construction professionals involved in beam design and load calculations will benefit from this discussion.

For a 4x4 beam 12' long supported by 4x4 8' tall colums I need to calculate the moment around A and B and the vertical forces at A and B based off the point load which for discussion purposes is in the middle of the beam but could be anywhere on the beam. Does anyone know the calculations? I understand the point load may be on the heavy side at 10000kn.

There is a link to a diagram of what I am referring to here (Points A & B):

What are the fixations at top and bottom of vertical beams and at connections of vertical beams to the horizontal one ?

You say 4 by 4 beams but are they solid wood or structural steel section ?

Well I think that these beams are hung with beam hangers made from steel and the fixations at the top an bottom should probably have break lines there. For discussion purposes the beams could be any material but I would like to use wood first if possible.
