Building Code: $2018$ IBC $/$ ASCE $7-16/$ AISC Steel Construction Manual $15$ th Ed$.$

Steel Framed Building. Concrete roof and floor slabs.

Building Use $$ Typical office building

Proposed Lateral Load$-$Resisting System: Steel special concentrically braced frames

Soil Type D

Dead Loads:

Roof Dead Load: $45$ psf $($including the roof equipment but not including the fa$$ade$)$

Floor Dead Load: $85$ psf $($including all partitions and equipment but not including the fa$$ade$)$

Exterior Fa$$ade: $12$ pounds per square foot of exterior surface area

Live Loads:

Roof: $20$ psf live load

Typical Floors $85$ psf live load

Consider Dead, Live, Snow, Wind and Seismic Loads for the design of all elements unless noted

otherwise

Determine the following:

$1.$ The wind loads acting on the building in both the N$-$S and E$-$W directions

$2.$ The seismic forces at each level in both the N$-$S and E$-$W directions

$3.$ Design the roof beam, B$1$

$4.$ Design the floor beam, B$1$

$5.$ Design the roof girder, G$1$

$6.$ Design the floor girder, G$1$

$7.$ Design the concentric bracing at elevation A$-$A $($blue location $/$ chevron$).$

Check both wind and seismic loads. Design both the typical bracing member and a typical

connection to the beam and a typical connection to the column.

$8.$ Design the concentric bracing at elevation B$-$B $($red location $/$ the X bracing is connected where the

members intersect $$ assume lateral bracing so L eff $-0\mathrm{.}75$L where L is the brace length$)$ Check both

wind and seismic loads. Design both a typical bracing member and a typical connection at the

beam$-$column joint.

$9.$ Design column C$1.$

$10.$ Determine the compression at the base of the column where it bears upon a concrete footing.

$11.$ Design the column base plate and the connection of the column to the concrete footing below. Use

f$$c of $4,000$ psi for the concrete footing. Rebar is fy$=60$ ksi.

$12.$ Design a typical foundation $($spread footing$)$ under column C$1.$ Provide a sketch$($s$)$ that shows the

geometry of the concrete footing, the steel reinforcement of the concrete footing and the

connection of the column$/$base plate to the footing. Soil bearing pressure is $4,000$ psf$.$ CVNG $4930/5930$
