Dynamic factor lifting

WebNov 10, 2024 · Dynamic Amplification Factor (DAF) is a dimensionless ratio. It represents how much a structural response to a static load magnifies, if the load were applied dynamically. The response is typically a specified displacement or stress value. A static load does not change with time, or changes so slowly that the inertial effects are negligible.
