Inclined slab concrete stair

• A concrete stair which spans between landings . 
• Where there are load bearing walls around the stair , it is generally economic to :

1. Build the landings into the side walls as one-way spanning slabs . 
2. Construct the flights as inclined slabs between the landings . 

• Suitable for used where the enclosing walls are of brick or block . 
• It would involve a great deal of wasteful cutting of bricks or blocks as :

1. The flights are to be built into the walls 
2. The bricks or blocks are cut to fit to the steps .
