The DuraFuse Frames connection meets the qualification requirements for both SMF and IMF frames. However, no test data are available for the DuraFuse Frames connection with composite slabs, so prequalification is restricted to the case where the concrete slab has a minimum separation or isolation from the column. In general, isolation is achieved if the slab is separated from the column face by an open gap or by use of compressible material.
