Input | Description |
|---|---|
Span Options | This input determines what 'L' to use when determining the allowable deflections Main Span: Sets L to the distance between supports Current Span: Sets L to the distance between the nearest left boundary condition and nearest right. For cantilevers this will use the cantilever length. Total Length: Sets L to the length of the member. |
Allowable Deflection | Sets the limit for deflection multipliers for both total and live load deflections. The deflection limit is always L, as defined above, divided by the inputted value. |
Transform Reinforcement | Tells the program how to handle reinforcement transformation when calculating section properties for deflections. For more information see Transformed Section Properties. |
Use mild to reduce deflection multipliers | Tells the program to follow the PCI Design Handbook to reduce the camber and deflection multipliers based on the ratio of As to Ap. |
Section Properties | Tells the program at what location the section properties should pull from. Varying: Tells the program to allow the section properties to vary down the length of the member. The section properties will be pulled for all locations. Midspan: Tells the program to use the midspan section properties as the section properties for all locations. At Supports: Tells the program to use the section properties at the supports. The software checks above both supports and uses the lower of the two section properties. |
Stiffness multiplier | Applies the given multiplier to the product of EI in the calculation of deflections. |
