Good work, friends. The project consists of a total of 16 floors, 2B + Z + 12 + Attic. As can be seen in the picture, the 1st period is 21,897. How can I fix this?
Hello, The stairs on the top floor are oscillating because the landing and support conditions are not properly adjusted. If you delete the ladder or define and connect the landing, the Period decreases to 1.48.
