An engineer observes that during a seismic event, the vertical response at a site required a V/H ratio of 0.45 for accurate design. If the site-specific horizontal spectrum has a peak ground acceleration (PGA) of 0.8g, what is the adjusted vertical PGA?
💡 Hint: Use the scaling formula involving V/H to adjust the values accordingly.
Discuss the potential consequences of applying a uniform V/H ratio of 0.5 across different soil types when designing a multi-story building. How would your approach differ if the building were to be constructed on soft soil versus hard rock?
💡 Hint: Consider how soil characteristics affect ground response.
