Camber and deflections are calculated at the 0.1L, 0.3L, and 0.5L (midspan). Prestress losses for deflection are calculated using the gross moment of inertia, Ig.

Deflections of self-weight and dead loads on precast for supported beams are computed based on formulas from statics. The deflections due to dead load on composite and live load are computed for the composite model. Uplift due to prestress is computed using the moment-area approach for each beam. Each strand group is treated separately with consideration given to individual strand transfer distances in the construction of the total M/EI diagram. Therefore, the effects of draping and multiple shielding can be handled accurately.

Deflection due to live loads will automatically be calculated. Long-term deflections are computed by multiplying the initial/release calculations by factors specified in the PCI Design Handbook (Fifth Edition), Table 4.8.2.
