Assalam o alaikum...
I have attached two images. One image titled STAIR TYPES and one image as titles SAMPLE STAIR.
STAIR TYPES image contain two drawings. Two different type of detailing for reinforcement. I am confused which out of two should be used and what basically structural difference is there? I think in STAIR 1 (see image attached) there is no moment capacity at connections of flight and landing etc whereas in STAIR 2(see image attached) there is moment resisting capacity at connections of flight and landing etc ...
SAMPLE STAIR image contain question problem. I am having this type of stair in my building where landing is supported at two intersecting sides and other two sides are unsupported and standing in air or connecting with flight. What type of reinforcement would be suitable for this case?
Thanks.
