1) A steel pipe is filled with concrete as ilustrated below. If an axial force of kN is applied to the composite column, compute t in the concrete and in the steel. Assume the pipe has an outsid mm and an inside diameter of 70 mm. ESTEEL 200,000 MPa, EcoNC [oSTEEL 48.8 MPa, ơCONCRETE 5.85 MPa] he normal compressive stress e diameter of 80 24,000 MPa 500 mm 2) A concrete column is reinforced using four steel reinforcing bars (rebars), as shown below. If each rebar has a diameter of 18 mm and the applied load is 800 kN, compute the normal stress in the steel and the concrete. ESTEEL 200,000 MPa. Eco c 24,000 MPa [ơSTEEL-68.3 MPa, ơcoNCRETE-8.21 MPa] 300 mm 300 mm 3.1 m
