Shear on simply supported beam
Shear on simply supported beam
(OP)
Guys, I am having another engineering discussion with my coworker. Let's say you have a concrete beam simply supported 10 ft long. You have 10 kips factored point load that can be anywhere on the beam. The beam has 12" d distance. What Shear load would you design the beam for? Let's neglect the dead load from the beam.

(neglecting semantics like AASHTO where you'd need to offset your critical section by dv instead of d, etc.)
RE: Shear on simply supported beam
why not be conservative at use 10 kip ? the difference seems small ...
another day in paradise, or is paradise one day closer ?

- >9 kip for loads closer to the support. At that point it would become either STM or a combination of shear friction and direct bearing rather than diagonal tension.
That's the theoretical answer that I believe we're debating. In practice, just 10 kip of course.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

A more interesting question is what is the maximum concentrated load which could be placed between the support and distance 'd' from the support?

For the original question, I would use 10 kips. Life's too short to go into any more detail than that...
