Punching shear provisions of ACI318-08

Punching shear provisions of ACI318-08

(OP)
When Paragraph 11.11.2.2 is used, the concrete strength value is limited to 4900psi "due to limited test data available for higher values".  Does anyone know of further experimental work in this area for higher strength concrete?

RE: Punching shear provisions of ACI318-08

Hokie,
good luck, Below is article that did some very limited testing (the P/A was too low for there tests to mean anything), i wouldn't bother getting it unless your a member of the ACI, I doubt it will be of much help really concentrates on the high-stength concrete.

Will keep my eyes open.
