STRUCTURES - BEAM REACTIONS

To find reactions for asymmetrical beams:

•  Draw an abstract beam diagram to illustrate computations
•  Use Σ M = 0 at one support to find reaction at other support
•  Verify results for vertical equilibrium




1 Floor framing
2  Abstract beam diagram

Support reactions:


Alternate method (use uniform load directly)


1  Simple beam with point loads


2  Beam with overhang and point loads 


3  Beam with uniform load and point load (wall)
