Zusammenfassung:	PURPOSE: A PC(precast concrete) slab for a long-span and high-load building and a construction method thereof are provided to minimize cracks generated between plates by efficiently transferring an unbalanced load to the plates. CONSTITUTION: A PC slab(10) for a long-span and high-load building is composed of a bottom part(11), multiple rib parts(12), and a top part. The bottom part is reinforced by reinforcing bars or wire meshes arranged in a latticed shape. The ribs are protruded from the bottom part in a longitudinal direction. Shear reinforcement bars(122) are arranged along the longitudinal direction of the ribs. The top part is formed on the top of the rib parts to be parallel to the bottom part. L-shaped reinforcing bars(131) for transferring an unbalanced load are arranged on both ends of the top part at uniform intervals.
