2 Story Masonry Stair Tower - SDC D
2 Story Masonry Stair Tower - SDC D
(OP)
I have a steel, braced frame, two story building in a seismic design category D. the architect has chosen to put masonry stair towers in the corners of the building.
I need to isolate this tower from my braced frames. The only solution i can come up with is laterally supporting the first floor and carrying the walls above with the floor steel at the second floor. the concern is carrying this vertical load with no slab backspan at the openings.
Seems like an easy solution, but has anyone else gone a different route?

Not to be a fly in the ointment even more, but nobody knew about the need for fire protected stairwells (usually CMU or concrete) at the kickoff meeting or sometime early in design? Wondering how that got overlooked until you are almost done with your lateral design. Not saying its your fault....

agreed on both points. However, we were brought on late into DD's after the first engineer was forced out.
we need more masonry than the towers provide, and we've also been told more masonry isnt an option.
fortunately, we have been able to solve the problem.
