3. The column shown below has its base fixed in a concrete foundation. The top is pinned. Determine the critical buckling load using a height of 18 feet, and assuming material has a modulus of elasticity of 1.2 x 10° psi. 3" X 5" Column Concrete Foundaion

A simply supported beam has a height of 600 mm and a width of 300mm. Determine the maximum safe live load that the beam can carry. The dead load is the beam weight plus a superimposed load of 15 kN/m The stirrup size is 12 mm, the top bars are 2-20 mm and the bottom bars are 5-28 mm. The clear distance between layers of bottom bars is the bar size, 28 mm. Use fc'=30 MPa, Grade 60 (fy=414 MPa) reinforcements and concrete cover of 50 mm.

Find the safest value of load "P" for the beam loaded shown. fc'=35MPA, Use GRADE 420 steel bar and n=10 The answer is kN. Assume unit weight of concrete = 24kn/cu.m. 200 3 m 1 m toort twit 3P 70 200 2-20 mm O 330 3. BEAM 4-32 mm Ø 300 100 DIMENSIONS ARE IN "mm"

Assume z = 0.85dEff a height of compression concrete stress block in mm. c distance from the neutral axis to outermost compression fiber in mm. z actual moment arm for Mu=ØTz in mm. As actual area of tension steel in sq.mm. N quantity of Ø20mm steel rebars ЄS Actual Strain of steel ЄY Yield Strain of steel Check if the beam is singly reinforced concrete in the designed then concludeCheck: ЄY < = > ЄS Draw the Working Drawings of the x-section.

Calculate maximum deflection of the concrete beams Check the suitability of the section assuming the code limitation of L/240. If maximum deflection doesn’t meet the code requirement, propose your solution
