LEAP Concrete defaults PCI Bridge Design Manual Table 8.7.1-1 for the deflection multipliers.

However, in the same section, it is indicated that the composite multipliers given in the table are not properly account for the significant effects of a large CIP deck, therefore values for composite topping should not be used for bridge beams with structurally composite CIP decks.

Please consider utilizing a different method to calculate deflection multipliers with composite topping.
