Seismic analysis of Uniflair floor stands

A structural analysis model was created for each of the frames for the Uniflair seismic floor stands, to verify that

the frames are adequate for the highest seismic forces (S

=2.5g). The reactions from the analyses were used

to calculate the maximum S

of the frame base assemblies.

For each frame type, the baseplate, welded bolt and nut, welds, and anchorage to the structure were evaluated

to determine the maximum S

DS of the base assembly. The anchorage of the baseplate to the structure was

assumed to be 2.5 in. HILTI Kwikbolt TZ expansion anchors with 2-in. embedment into a 4-in. thick normal

weight concrete slab with the strength of fc’=4000 psi using the attached base plate. The results of the analysis

are provided in the following table.
