Modified PCI Multipliers for Time-Dependent Deformation of PSC Bridges

Table 5

Proposed multipliers.

	Without topping	With topping
At erection
(1) Deflection (downward) component—apply to the elastic deflection due to the member weight at transfer of prestress
(2) Camber (upward) component—apply to the elastic camber due to prestress at the time of transfer of prestress
At certain time
(3) Deflection (downward) component—apply to the elastic deflection due to the member weight at transfer of prestress
(4) Camber (upward) component—apply to the elastic camber due to prestress at the time of transfer of prestress
(5) Deflection (downward)—apply to elastic deflection due to superimposed dead load only
(6) Deflection (downward)—apply to elastic deflection caused by the composite topping	—
Final
(7) Deflection (downward) component—apply to the elastic deflection due to the member weight at transfer of prestress	2.70
(8) Camber (upward) component—apply to the elastic camber due to prestress at the time of transfer of prestress	2.45
(9) Deflection (downward)—apply to elastic deflection due to superimposed dead load only	3.00	3.00
(10) Deflection (downward)—apply to elastic deflection caused by the composite topping	—	2.06
