Re: ACI318-95 Permissible concrete tensile stress in prestressed concrete

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Wontae,

It is now covered by 18.3.3. In it the factor of 6 is increased to 7.5 but I am sure an amendment was released soon after that reduced this more correctly back to 6.



At 12:50 AM 31/01/2006, you wrote:
18.4.2 (c) and (d) of ACI318-95, perimissilbe concrete tensile stress equal to 6 sq rt f_ci and/or 12 sq rt f'_c in precompressed tensile zone, were removed in ACI318-02.
Can anybody give me background info about this change?
