My firm is planning a processing facility in Zone 3 (1997 UBC) that is expected to be about 550' wide and 1100' long. I am planning to provide expansion joints along the length, but I am not sure how expansion joints are typically handled in high seismic zones. The following questions come to mind:
- If two expansion joints are used, at say 400' from each end of the building (dividing the long dimension into 400', 300' & 400' sections) how does the lateral load system get detailed? Is each section considered a separate part of the building?
- Would double column lines be required at the expansion joints effectively dividing it into 3 buildings?
- If double column lines are provided at each joint, I assume the distance between the columns must be based upon the expected drift between the sections to avoid any impact between the sections during a seismic event (effectively dividing the building into three separate structures)?
- Is there a way to provide the expansion joints without dividing the building into 3 separate sections so that it can be considered one structure for drift calculations?
- Any product recommendations for these types of joints?
Any information that can be provided would be greatly appreciated.
