RE: what is the allowable beam opening?

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I ran into a similar problem about a year ago.  I searched the ACI journal database and found some helpful articles for aiding in design.  I will check in my folders for the specific articles I found.  I remember one method approached the problem by modeling the beam with differing stiffnesses to account for the holes.  There were also methods proposing a strut and tie model.

True, but the design guide will help him understand the principles

The question was about a concrete beam, not steel.

From memory the middle third of the beam depth. But otherwise design the beam for the hole.

what is the allowable beam opening for MEP utilities to pass or penetrate through concrete beam? is there any probition in the code that allows opening or holes in beam? thank you.
