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. WebJul 27, 2010 · This is similar to what a crane (or lifting sling) sees when dynamically loaded. Your dynamic factor should be 2.0 and your static safety factor should be 1.5, 1.67 or 1.92 (tension, bending and buckling), resulting in an overall SF of 3.0, 3.33 or 3.84 against yield, just to name a few general cases.
