Seismic Joint between buildings
Seismic Joint between buildings
(OP)
I'm working on the design of a pedestrian bridge that will connect to a large parking garage structure. The general consensus in the office is that there should be a joint separating the bridge from the garage. I'm not sure I understand why. Does anyone havbe any ideas?

2: You still can model your thing without the joint BUT:
You will get a hell of concentrated complix stresses around the bridge supports and in the bridge members and you will not be able to design nither the bridge nor his supports.
Finnaly: Even if the two building will have similar periods and both of them are classified as short (4 storey max) you cannot predict weather they will act simultaniously(and they will not)if you join, you will still have problems.

Say for instance you have a 500' long, tilt up warehouse bldg. It has full length and height load bearing partition walls that separate the structure into 5 equal pieces.
You would put in joints at each interior wall for thermal changes and also enough of a gap to prevent seismic pounding, even though the periods of each segment should be the same?

2- These two buildings will not act the same
3- As stated: joining the two will lead to unpredicted stresses.

I meant seismic movement joints at the roof level on one side of each of the 4 interior tilt bearing walls. Like a typical expansion joint at the roof, located adjacent to each bearing wall.
I think Rawand is indicating that they would be required.
