Use A$36$ steel and select a structural tee for the top chord of the welded roof truss shown in

the figure below. All connections are made with longitudinal plus transverse welds. Assume a

connection length of $279\mathrm{.}4mm.$ The spacing of trusses in the roof system is $3\mathrm{.}81m.$ Design

the following loads.

Snow: $0\mathrm{.}9576$ kilopascals of horizontal projection

Roofinq: $0\mathrm{.}5746$ kilopascals
