Seismic Design of a New Room in an Existing Structure


I am designing a room by using cold frame steel in an existing building. Any ideas or examples or design guides about how to calculate to the seismic force for the new room in an existing building ? The room is a simple box..

Thank you,

RE: Seismic Design of a New Room in an Existing Structure

You might not need to do a full analysis. The code has a threshold of 10% I believe. If the seismic weight being added to the structure is less than 10% you don’t need to do anything. I would imagine for your case the additional weight would be the weight of the partitions plus any live load depending on the type of loading.
