1. Continuous Stairs Ajith Kumar M M Roll : 4 S4 B.Arch

2. Continuous stairs are those which do neither have any landings nor any intermediate newel post . The stairs only have one single flight . This is almost always the most efficient and economical way to achieve the necessary rise. 

3. Although simple in design and construction, is not popular because of the plan space it occupies The flight behaves as simply supported slab, spanning from landing to landing. The effective span/total horizontal going is usually taken as landing edge to edge by providing a down stand edge beam to each landing . If these edge beams are not provided, the effective span would be taken as overall of the landings, resulting in a considerably increased bending moment and hence more reinforcement.

5. ADVANTAGES Straight stairs tend to be the easiest to go up and down or ascend/descend as we say in the industry. They are typically the easiest to build. Straight stairs only need to be connected at the top and the bottom, no intermediate supporting structure is required . By selecting transparent materials, straight stairs can be made more transparent than other types of stairs allowing less obstruction to the view beyond. No landing is required if the number of risers are kept under 12.

6. Disadvantages Straight stairs use up a fair amount of linear space which has to be planned for in your design. Some of the other stair types create a privacy barrier between the floors of your home. Straight stairs do not offer this privacy. A stair after 12 risers requires a landing to break up the span. The addition of a landing will use up allot more space.
