4.2. Critical Load Cases

Try these first

1. 1.

   What is the maximum imposed load on flat roofs according to IS 875 Part 2?

   Hint

   Check the code for requirements related to roof types.

2. 2.

   Define what imposed loads are.

   Hint

   Consider what activities or factors might change these loads.

3. 3.

   What type of load can vary depending on occupancy and usage?

   • Dead Load
   • Imposed Load
   • Wind Load

   Hint

   Think about which loads are directly related to people or activities.

4. 4.

   True or False: Sloping roofs do not experience suction pressures.

   • True
   • False

   Hint

   Recall how wind interacts with different roof surfaces.

5. 5.

   Given a flat roof with a maximum imposed load capacity of 3 kN/m², calculate the total load for an area of 50 m².

   Hint

   Apply the area to the imposed load.

6. 6.

   Design a simple truss capable of withstanding 1000 kg of load, taking into account dead load, imposed load, and wind load factors. What design considerations should be made?

   Hint

   Use known material behavior under various load conditions.
