Composite Behavior | Tells the program to use either the precast section for shear, or the full composite height for shear. If the composite height is used for shear the minimum concrete strength is used. |
Treat as Slab | If the member is being treated as a slab, it allows Vu to go up to phiVc before reinforcement is needed. This option allows the user to apply ACI 318-14 7.6.3.1. Note that it does not check the height requirement of this provision. |
Shear Horizontal
More information on these options can be found on Horizontal Shear.
Method | Can selected either the ACI General Method or the PCI Design Handbook method. |
Shear Force Considered | For the ACI method only. |
Horizontal Shear Stress | For the ACI method only. This option controls which method should be used for determining the horizontal shear stress. VQ/Ib is typically considered an elastic response where V/bd can be used for both elastic and elastic responses. |
Use effective mu for shear friction | The effective coefficient of friction from the PCI Design Handbook will be used if checked. This is only valid if no load reversal is present. |
Compression Steel | Additional steel in the slab. This steel is assumed to be yielding in compression and produces additional compression stress in the top slab. |
Torsion
Method | Selected whether to use the ACI Method, Zia Hsu method (with plate bending near ends) or slender spandrel for handling torsion |
...
Transfer
Support Locations | Picking what boundary conditions to use for the transfer stage. |
Compression Limits | Limits for compression. |
Tension Limits | Limits for tension. If this value is exceeded, reinforcement will be required. |
End Zone | The end zone limits for transfer are within the computed transfer length of the ends of the member. |
Allowable Bar Stress | ACI Limit: Uses the minimum of 0.6 times the bar yield and 30 ksi as the allowable bar stress PCI Recommendation: Uses the minimum of the bar yield and 60 ksi as the allowable bar stress. |
