AW14 x 53 of Grade 70 steel is used as a compression member. It is 30 feet long, pinned at the top and fixed at the bottom, and has additional bracing in the weak direction. The column is braced (pinned) on its weak axis 10 ft form the top and bottom. What is the nominal strength in axial compression for the member? O 659 kips O 761 kips O 856 kips O 733 kips

What is the internal force acting on member DF, EF and EG? Please dictate if its in compression or in tension. Complete solutions please.

Considering the frame, the height of each storey is 5 m (DA) and 4m (DG) , the length of each span is 6 m (GH) and 7 m (HI), assuming columns and beams have the same cross sectional areas. *Using portal method, what is the axial force at column FC?

2. Calculate the internal forces in the bar GF and GD in a roof truss as shownbelow. For each bar, indicate if the internal force is tensile or compressive. Usethe section method (snittmetoden). Point A has simple support and D has rollersupport.

The service load bending moments on a beam are 128 kip-ft for dead load and 107 kip-ft for live load. The beam is 12 in. wide, f'c is 3000 psi and fy is 60 ksi. Determine Mu. Mt. p. R. the depth of the beam and the As of tensile reinforcing required. How many no. 8 bars or No. 10 bars would have the required As?

From A to B it is 7.5ft, from A to G it is 24ft.

Determine the force of the members for the space truss shown in the figure. Joints A and B are supported by ball-and-socket while Joint C is supported by short link along z-axis. Indicate whether member is tension (T) or compression (C). 2m y Sm Az By BX Bz PAR Ax CSXScanned with Ca canner a SISU KN 15m 1 2117
