What does SSI stand for?
Think about the interactions happening during an earthquake.
What happens to a structure’s natural frequency when built on soft soil?
Recall how flexibility affects oscillation.
Soil-Structure Interaction (SSI) affects a structure's dynamic behavior.
Think about the foundation.
The natural frequency of a structure on soft soil is higher than on firm ground.
Recall what flexibility does to frequency.
Analyze a scenario where a tall building is placed on very soft soil. Discuss the expected challenges in its seismic performance and possible design solutions.
Consider the relationship between soil behavior and structural response.
Critically evaluate the implications of disregarding soil-structure interaction in a seismic retrofitting project for an existing building.
Reflect on how existing soil conditions can influence the new design.
