The integrations needed to determine beam deflections require the enforcement of the appropriate displacement and rotation boundary conditions (BCs). It is important that we be able to recognize these ...

DEAR TIM: I’m getting ready to build a large room addition that needs a beam to support the floor joists. I’ve been told that a wood beam will work, but I’ve always seen steel I-beams in other houses.

When used in structural engineering, the term deflection refers to load-induced displacement, which typically affects beam designs. It can be an extremely complicated value to calculate when ...

Q. I'm getting ready to build a large room addition that needs a beam to support the floor joists. I've been told that a wood beam will work, but I've always seen steel I-beams in other houses. Is it ...
