We are using fixed base columns to limit the drift of a small ordinary moment frame building with high floor to floor heights. The building is in a high seismic zone. We are planning to pretension the anchor bolts to ensure a fixed base condition with no rotation at the base. Is this
reasonable use of pretensioned anchor rods? If so, are there any guidelines for determining the adequate pretension force to be used?
