To study the influence of stair end platforms on the deflection and stress distribution of stairs,and analyze the design theory of staircase,according to the classification of slab staircases in the building standard drawings,the finite element software ANSYS was utilized to simulate four slab stairs:AT,BT,CT,and DT.With different end platform sizes,various stair slab thicknesses,and diverse load types,the deflection and stress performance of slab stairs was analyzed.The results showed that the deflection was a key factor in control-ling staircase design.It was advisable to correct the deflection of stairs during the design process to make the de-sign more reasonable.The maximum deflections of AT and the DT type slab staircase were close,while thede-flections of BT and CT type were close.With the size of the end platform increasing,the staircase deflection decreased,and the concrete stress distribution at the stair support changed.
