5. Structural Dynamics and Seismic

Seismic Design — Quiz

Test your understanding of seismic design with 5 practice questions.

Practice Questions

Question 1

Which of the following seismic analysis methods is generally considered the most sophisticated and is often used for complex or irregular structures?

Question 2

When designing a structure for seismic loads, what is the primary purpose of the overstrength factor ($\Omega_0$) in code-based calculations?

Question 3

A building is located in a region with a design spectral response acceleration at short periods ($S_{DS}$) of $0.8g$ and a design spectral response acceleration at $1$ second ($S_{D1}$) of $0.4g$. The building has a fundamental period ($T$) of $1.2$ seconds, a response modification factor ($R$) of $6$, and an importance factor ($I_e$) of $1.25$. The long-period transition period ($T_L$) for the site is $6$ seconds. Calculate the seismic response coefficient ($C_s$) for this building using the ASCE 7-16 formulas: $\text{If } T \le T_L: C_s = \frac{S_{DS}}{R/I_e}$ $$\text{If } T > T_L: C_s = \frac{S_{D1}}{T(R/I_e)}$$

Question 4

Which of the following best describes the concept of P-Delta effect in seismic analysis?

Question 5

In the context of seismic design, what is the primary function of a fuse element?
