OTH396: The figure shows a 5m high concrete column supporting a load P = 80 kN. The cross-sectional dimensions: Civil Engineering Assignment, NUS, Singapore

Question 4

The figure shows a 5m high concrete column supporting a load P = 80 kN. The cross-sectional dimensions at the top and bottom are 0.3m by 0.3m and 0.4m by 0.4m, respectively. Determine the decrease in height of the column. E = 200 GPa.

Question 5
For the beam loaded as shown in Figure Q5, calculate the reaction force at A and draw the shear force and bending moment diagrams. Determine the maximum shear force and bending moment and where they occur on the beam. Assume the units for P, q and M are kN, kN/m and kNm, respectively, and all dimensions to be in m.

Question 6
For the beam loaded as shown in Figure Q6, draw the shear force and bending moment diagrams and use these diagrams to determine (a) the shear force at point B, and (b) the bending moment at support A.

(Note that the bending moment at pin C is zero. Ensure that your answers follow the sign convention).

Question 7

For the beam loaded as shown in Figure Q7, draw the shear force and bending moment diagrams and use these diagrams to determine (a) the shear force just left of point C, (b) the bending moment at point C, and (c) the maximum shear force and bending moment.
