A building has a mode shape of 0.6, a modal participation factor of 0.5, and a spectral acceleration from the response spectrum of 2.0. Calculate the peak modal response.
💡 Hint: Use the formula for peak response carefully!
Consider a system with three closely spaced modes. Discuss how you would analyze their combined effect using both SRSS and CQC methods, considering their differences in accuracy.
💡 Hint: Focus on understanding how the two differ when dealing with closely spaced frequencies.
