39.3. Design Philosophy as per IS 1893 (Part 1):2016

Try these first

1. 1.

   What does ductility mean in the context of structural design?

   Hint

   Think about how materials behave under stress.

2. 2.

   Define base shear.

   Hint

   Consider forces acting horizontally during seismic activity.

3. 3.

   What does the Importance Factor (I) represent?

   • A measure of building weight
   • A multiplier for base shear based on structure significance
   • A static load calculation

   Hint

   Think about critical structures like hospitals.

4. 4.

   True or False: The Response Reduction Factor (R) is used to increase seismic loads.

   • True
   • False

   Hint

   Consider how flexible structures behave during seismic events.

5. 5.

   Calculate the base shear for a 10-story building weighing 200 tons, located in a high seismic zone where the seismic coefficient is 0.2.

   Hint

   Remember to convert tons into a consistent unit if needed.

6. 6.

   Discuss how the design spectrum is relevant for a structure located on soft soil as opposed to hard rock.

   Hint

   Reflect on how ground conditions influence seismic design.
