The frame shown below is supporting an external moment of 200 kN.m. Considering the members' relative flexural stiffness (in term of I and L) shown on the figure: 3-1) (12 marks): Determine the moments exerted at the following members 'ends: a) MAB= ----- kN.m, b) MAC= kN.m, c) MAD= - kN.m d) MDA= ------- kN.m MA =200 kN.m e) MBA=- kN.m f) MCA= 11-21 I=21, L=L | I=31, L=L b) (8 marks): Draw the shear force and the moment diagrams on the beam DAB, assume L=5 m and show values 3 m Question 4 (8 marks): The beam shown in the Figure below carries a total ultimate uniform load of 30 kN/m. The beam section is shown. Use f'c = 25 MPa, and fy = 420 MPa, fys= 300 MPa. Check if the given steel (As) and the section is adequate to resist the applied Mu, and check if it is ductile enough for using a reduction factor $=0.9. Wu = 30 kN/m 3 m Question 5 (12 marks): (Use fe' = 25 MPa and f = 420 MPa) For the shown beam cross section: a. (2 marks) Calculate the cracking moment b. (4 marks) Calculate P, Pmin, Pmax, Pb, c. (2 mark) Calculate &, What is the type of failure according SBC code? d. (4 Marks) Calculate the ultimate design moment capacity? 2.0 kN.m 600 mm 600 mm As=3618 300 mm 4-422 mm * 350 mm 525 mm Question 6 (12 marks): The cantilever beam shown in the figure below supports a dead load of 7 kN/m excluding its own weight and a live load of 12 kN/m. Assuming, d= 340 mm, concert unit weight is 25 kN/m, fc' = 30 MPa and fy=420 MPa): DL= 7 kN/m without the self-weight, LL =12 kN/m 400 mm 525 mm 200 mm a. (8 marks) Assuming tension failure, determine the required area of the tension steel As b. (2 marks) Select appropriate bar size (diameter) and the number of the bars c. (2 marks) Sow the location of the steel bars (reinforcement details) on longitudinal and cross sections. The frame shown below is supporting an external moment of 200 kN.m.
