Challenge Problems
Push your limits with advanced challenges
Consider a building with a natural period of 0.5 seconds subjected to a given seismic event. Calculate its spectral response if the spectral acceleration for 0.5 seconds is known to be 1.2g. Determine peak force experienced.
💡 Hint: Ensure you have the mass of the building to complete the calculation.
If a structure has varying damping ratios of 5% and 20%, how would these ratios affect the spectral acceleration? Provide a scenario considering real structural dimensions.
💡 Hint: Refer to the generated spectra curves and compare their peak response values.
