Abstract： Three connection methods of precast concrete staircases (PC stairs) were discussed about integral calculation, factory production and construction convenience. High-end fixed hinge supports, low-end sliding hinge support connection mode has the advantage, and it is suitable for popularization. The analysis of the PC staircase under three stress conditions were done, the design idea of PC stairs, calculation points and construction requirements were given. The method is applied in the engineering case.
