Seismic Upgrade
Seismic Upgrade
(OP)
In a church designed in 1965, and not designed for seismic, we are investigating removing a column and installing a beam to pick up the load. Of course we would stringently limit deflection, pre-load the beam, check all elements including the foundations, base plate, and columns which would pick up the load.
Question:
Given that the current Ontario Building Code requires new buildings to be designed for seismic, is there any requirement that this 1965 building be upgrade for seisimic because of the column removal? Or can the existing structure still be grandfathered in?

RE: Seismic Upgrade
In many cases, bringing a building up to current codes kicks in when you are remodeling/renovating over a certain percentage of the value of the building. In California, I've been involved in a few projects where the upgrade was essentially up to the owner after we briefed them on the relative merits/risks/costs etc.
