CIV2235—STRUCTURAL MATERIALS

Week 9 Practice Class

Actions and Action

Assume that you are designing an office building of 10 stories. The floor plan is given in Fig

1 and the cross sections are shown in Fig 2. The data for the problem is:

n Density of concrete: 2500 kg/m3

n Superimposed dead load: 1.5 kPa

n g = 9.8 m/s2

n The distance from top of slab to top of slab is 4 meters

n The floors and roofs thickness is 130 mm

n Column C1 is a circle of diameter of 900 mm .

 

Fig 1. Floor plan .

 

Fig 2. Cross sections at AA, BB and CC.

Question 1. Determine the dead load and live load in the slab (10 marks) .

Question 2. Determine the dead load and live load in the joist (secondary beam) B1 (20 marks) .

Question 3. Determine the dead load and live load in the girder (primary beam) B2 ((30 marks) .

Question 4. Determine the maximum bending moment and shear force in B2 for permanent action (20 marks) . Assume the supports are simple supports .

Question 5. Determine the maximum bending moment and shear force in B2 for imposed action (20 marks) . Assume the supports are simple supports .
