100-year-old 3-story brick building renovation
100-year-old 3-story brick building renovation
(OP)
Dear,
I have recently invited to a renovation job. That can be described as "100-year-old 3-story brick building renovation". There is only brick walls (the brick condition is pretty good) and wood floors. I cannot find any lateral system.. except teh brick walls. Hmm this is interesting. how this building resists the wind pressure?
I will remove the entire 2nd level wood floors (which may be a part of lateral diaphram) and reinstall new floors about 5' above from the current 2nd floor level.
With so many unknown factors, I need to be advised by many experties to make a feasible demolitiona/renovation plan for the building. This seems a very complicated project I have never tried before.
I will aprreciate it if you are willing to share your great knowledge with me. Thanks.

With changes in life styles, homes have more humidity and are generally more air tight. You have to be careful about the building envelope too.
That said, your interior partitions could be providing a substantial stiffness to the home and some skill and care in selecting what can and cannot be removed is required. The original walls could be wood lath and plaster which if in good condition is 'very' stiff and provides a substantial lateral stiffness.
Just some caution when dealing with historic masonry.

The building has been used as a warehouse and there are not much partition walls. The perimeter wall is the prime gavity system and lateral system as well.
The 3-story height perimeter walls are braced by the wood floor and the wood floors (as a diaphram) are redistributing the later forces to the adjacent transverse direction brick walls which is kind of big partition walls (about more than 50' spacing). Well.. the building has more likely empty inside.
If this is the typical historic brick building strutural system, do you have any suggestion before I try to remove the second floor level wood deck frames? Any lateral stability issue? I cannot imagin the building collapsed after I remove some part of the existing system.
Thanks for any opinion.

I have much better feeling on this project now. Still I have to think about the transvers direction shear resistance system using brick partitions or something else, otherwise this building will never meet new IBC seismic requirement to complete the massive renovation. It is a bit amazing this building is still standing without such lateral stiffness and without any trouble. It is lucky this site is not in severe seismic zone.
Thanks for your great idea and concern. feel free to add any comments. Thanks
