ForASD/LFD rating, LARS assumes capacities for negative moment regions ofcontinuous prestressed beams to be based on reinforced concrete sections(AASHTO Section 8). The positive moment region capacities are computedbased on prestressed concrete (AASHTO Section9). For LRFR rating, LARS uses the unified capacities for Concrete Structures (AASHTO LRFD Section 5).
