Re: Building Expansion Joint

[Subject Prev][Subject Next][Thread Prev][Thread Next]
what type of expansion joint are you talking about?  a seismic expansion joint?  that would be determined by the inelastic drifts of adjacent structures.  or are you referring to expansion joints in a concrete or masonry structure?  that's more for relieving stresses due to the shrinkage of such materials.  more like 1", and not 12" for a seismic joint.

Does anyone clarify that expansion joint is based on inelastic
deflection like elastic deflection x Cd due to seismic load?
