32.5.2. Seismic Coefficient Method (IS 1893)

Try these first

1. 1.

   What is base shear?

   Hint

   Think about forces acting on structures during earthquakes.

2. 2.

   What does IS 1893 provide for engineers?

   Hint

   Consider the role of codes in construction.

3. 3.

   What is the formula for calculating base shear?

   • V = A ⋅ L
   • V = A ⋅ W
   • V = W / A

   Hint

   Remember the components used in the base shear calculation.

4. 4.

   True or False: The Seismic Coefficient Method can be applied only to multi-story buildings.

   • True
   • False

   Hint

   Consider the types of structures covered by seismic codes.

5. 5.

   A 12-story building with a total weight of 1200 kN is located in a region with a seismic coefficient of 0.25. Calculate the base shear and discuss how this impacts the design.

   Hint

   Use the base shear formula.

6. 6.

   How will an increase in the height of a building from 5 stories to 10 stories affect the seismic coefficient if the total mass remains the same?

   Hint

   Consider how height impacts force distribution in structures.
