1. Draw Shear force and bending moment diagram for the following beam.

2. Find the axial force for the member AB and AC

3. A rectangular column of 15” x 15” section has reinforcement of 8 no. 9 bars. If the value of f’c is 3000 psi and fy is 60000 psi, find the ultimate design axial load of the column with zero eccentricity.

4. Write down the standard value of the following parameters.

Solution:

5. A falling head permeability was performed in a permeameter with an inside diameter of 5 cm. The inside diameter of standard pipe was 2 mm. The sample had a length of 8 cm. During period of 6 min, the head on the sample decreased from 100 to 50 cm. compute the value of K.
