penetrations through concrete beams
anyone have any good references for designing penetrations through concrete beams? thanks.
check out our whitepaper library.
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.
also, you can freely download from the collaboratory site at mathsoft a worksheet doing the small circular opening calculation as per mansur.
