Challenge Problems

Push your limits with challenges.

Question 1

You are designing a building in a region classified as having medium soil. The local building code recommends a damping ratio of 5%. If the natural period of your structure is 1 second, calculate how you would approach deriving the Sa for the structure.

💡 Hint: Refer to IS 1893 for specific tables that outline Sa based on these inputs.

Question 2

A structure with a natural period of 2 seconds is located on soft soil. If the spectral acceleration value derived from code-specified spectra is 1.5g, how would the presence of a high damping ratio (e.g., 15%) affect your design considerations?

💡 Hint: Remember to use the damping correction factors from the relevant standards.
