ACI 318-83

ACI 318-83

ACI 318-83

(OP)
I am trying top determine what the load factors and resistance factors were from the 1983 ACI-318 code.  

Mainly I am looking for the factors for the DEAD and LIVE loads as well as the resistance factors for FLEXURE, COMPRESSION, and SHEAR.  Any help would be appreciated.

Thanks

RE: ACI 318-83

Nilsson and Winter's 1986 book on reinforced concrete design has a table of load factors from the 1983 ACI code, to wit:

U = 1.4 D + 1.7 L, etc.

Resistance factors for flexure = .9
                   for axial comp = .7
                   for axial tension = .9
                   for shear = .85

RE: ACI 318-83

wubwub,

DaveViking is correct. I have the 1983 code (actually all of them from 1963)  and the only addition to DaveViking's list is that phi for axial compression/axial compression with flexure with spiral reinfrocement is 0.75.

FYI, the 1963 code used 1.5D + 1.8L and the 1971 code was the first to go with 1.4D + 1.7L.

Thank you both for the answer.  The person who used to have the old codes in the office took them with him when he left.

Thanks
