Steel L-6m, 0-25mm, 2.5m 4.5m E=200GPG 0-15mm, E-70GP B A PRODT Q1) (20Marks): Find the max allowable load (P) which can be supported by three rods as shown in Figure (1) so that the stresses are not exceeding (150MPa) in Steel and (100MPa) in Aluminum, assume that the floor is to be rigid but it is not necessary to remain horizontal also the force at (B) is equal to the force at (C)? Aluminum L-4m, Figure (1)

A rectangular tied braced column is reinforced with 6-28mm bars as shown in the figure below. Check the adequacy of the column for the following gravity loads: - - - - - - Service dead load = 1050kN Service live load = 850 kN Service dead load moment = 39 kN-m Service live load moment = 27 kN-m top=bott. = 1.0 40 lu = 5.0m f = 27.6 N/mm², fy = 414 N/mm² axis of bending 500mm Ties 10mm@300c/c } 350mm At eccentricity of 40mm P M +40 + 500mm MU +40- P Top end Bott. end

Please Determine the axial load strength and moment (without and with reduction factor) a square columns for the following conditions and draw their interaction diagrams (note the scale): When conditions are in balance During the tensile condition When the pressure condition Pure axial Pure moment

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?
