Setting the Allowable/Limiting Stress Factors

Following are the references to the specification sections which control the allowable and limiting stress factors that are used by CIP RC/PT Girder for code checking and design:

  LFD LRFD
Compression -- Permanent + LL 9.15.2.2a 5.9.4
Tension -- Permenant + LL 9.15.2.2 5.9.4
Compression -- PS + Perm 9.15.2.2b 5.9.4
Tension -- PS + Perm 9.15.2.2c (CT) 5.9.4
Compression -- 0.5 (PS + Perm) + LL 9.15.2.2c 5.9.4
Compression -- PS + Perm + TU 7.2.2* 3.4.1
Compression -- PS + Perm + LL + TU + 0.5TG 7.2.2* 3.4.1
Tension -- Cracking Tension 9.15.2.3 5.9.4
Compression -- Release 9.15.2.1 5.9.4
Tension -- Release 9.15.2.1 5.9.4
Max 9.15.2.1 5.9.4

Max: 9.15.2.1 5.9.4

Setting the Resistance Factors

Following are the post-tensioning and reinforced concrete resistance factors that are used by CIP RC/PT Girder for code checking and design:
  LFD LRFD
PT Flexure 9.14 5.9.4
PT Shear 9.14 5.9.4
RC Flexure 8.16.1.2.2 5.9.4
RC Shear 8.16.1.2.2 5.9.4

Setting the Magnified Ext Girder Shear Factors

Enter the maximum exterior girder shear factor to be used when the limiting pier skew is reached. Shear factor values for pier skews less than the limiting skew will be interpolated between 1.0 and the maximum shear factor.
