A $6-$storey office building is being constructed in $719$ Main St$.$ East, Hamilton, Ontario. The plan

dimensions of the building are $55m(N-S)$ by $40m(E-W)$ and it may be considered a regular

structural configuration. The building's seismic force resisting system consists of a series of

ductile concentrically braced steel frames in the East$-$West direction and conventional steel

moment frames in the North$-$South direction. The geotechnical engineering consultant's report

cited a bore hole analysis which identified a combination of very dense soil and soft rock at the

proposed building site. The typical storey height is $2\mathrm{.}85$ metres and the building contains a flat

roof with $5-$ply felt paper and gravel. Typical floors consist of a $75mm$ concrete slab on metal

corrugated decking $($assume $1\mathrm{.}8$kPa $),$ floor finishes $)$ and with electrical and duct

allowances of $0\mathrm{.}25$kPa. Site specific snow loading and seismic information for this location can

be found online using the $2020$ NBCC Seismic Hazard Tool. Use the NBCC $2020$ Equivalent

Static Force Procedure to compute the lateral seismic load, V$,$ for the E$-$W building direction

only.
