Monument Stairway Code 3 Floors

I keep meaning to dig through and see if there s any way the pedestrian bridge could be counted as a means of egress.
Monument stairway code 3 floors. No interior or exterior stairs that are not part of a required means of egress do not have to meet the standards. Stair tread depth is more of an issue for descending rather than ascending stairs. There were 3 sets of double doors opening on to them from a small church and the egress only required two 60 paths of travel. Taipei 101 comprises 101 floors above ground as well as 5 basement levels.
Further the tread measurement of every tread in a stairway should be as close as possible to identical. It was not only the first building in the world to break the half kilometer mark in height but also the world s tallest building from 31 march 2004 to 10 march 2010. The greatest tread depth within a flight of stairs cannot be more than 3 8 inch larger than the smallest tread depth. Hence 4 5 times larger than required.
These stairs are approximately 45 in width the 2 walls have handrails and then there are 2 center double sided handrails in the middle. As of 18 april 2019 it is still the world s largest and highest use green building. If the distance between floor levels exceed 147 inches the flight of stairs would require a level landing somewhere in between to break up the flight of stairs. Sides 6 1 3 5 6 and specify at least 2 but no more than 4 flat steps at escalator entrances and exits 6 1 3 6 5.
The code establishes a maximum vertical height of 147 inches 12 feet 3 inches between landings or floor levels for a flight of stairs. 2 story mostly a3 building 9000 sf first floor 5000 2nd one fire stair one non egress monumental stair and a second floor exit on to a non combustible but open pedestrian bridge not at grade.
