Thank you for the information! I really appreciate it. I could use the
AISC manual, but a bit bulky for what I am doing at the moment. All I need
is the shape detailing dimensions.
Thanks again,
Joe Grill

>> Concrete Drop Panels
>>
>> ACI has a drop panel requirement:
>>
>> Section 13.3.7.2 - Projection of drop panel below the slab
>> shall be at least one-quarter the slab thickness beyond the drop.
>> ???
>> This wording has confused me. I think however, that it means
>> the drop panel, to be considered a drop panel, shall be at
>> least a 1/4 of the slab thickness, so if I have an 8" slab,
>> then the drop panel shall be at least 2", giving an overall
>> depth to the panel of 10" which includes the slab... no???
