expansion joint size
what is the maximum practical expansion joint size that can be used between a 37-story residential tower and 10-story parking garage building. deflections at the 10th story are high.
thanks,
check out our whitepaper library.
look at the publication mentioned in this thread, it may help:
contact balco. they have some joint systems that can accomodate 4" of movement. larger than that you may have to go to a custom design.
