( x- 4bays @ 2m at level y = 6m, y- 2story @ 6m & 2m, z- 3bay @ 5m) Edit the analysis and design commands of frame members under the effects of the following load conditions: i. Self-weight with Factor Safety (F.S.=1.2) ii. Imposed roof load 1.5kN/m2 with (F.S.=1.2) iii. External live loads shown in frame with (F.S.=1.3) Notes: Fy = 35 ksi, Es = 29000 kip/in2, edit analysis result for combination load only. Steel member section (frame column W6X15), Truss frame (vertical C8X13), (horizontal in x and z direction W8X21at level y = 6m), (horizontal in z direction double C10X30 at level y = 7m and y =8m), (external inclined double angle L3X2X3/16), (internal inclined angle L2.5X2X3/8), roof thickness 3cm, permissible ratio= 0.90, expanded output design results, with total volume materials table.
