Penetrations through Concrete Beams

Penetrations through Concrete Beams

Penetrations through Concrete Beams

(OP)
Anyone have any good references for designing penetrations through concrete beams?  Thanks.

RE: Penetrations through Concrete Beams

ACI Structural Journal Vol. 96 NO. 5
675 Design of Reinforced Concrete Beams with Small Openings under Combined Loading
M.A. Mansur

This one above is for small circular Openings.

ACI Structural Journal Vol. 96 NO. 6
899 Effects of Creating an Opening in Existing Beams
M.A. Mansur, K.H. Tan & W. Wei

For door, window and bigger rectangular holes it is useful a look to books related to rectangular holes in shear walls and vierendeel beams.

RE: Penetrations through Concrete Beams

Also, you can freely download from the Collaboratory site at Mathsoft a worksheet doing the small circular opening calculation as per Mansur.
