How is the Dynamic Amplification Factor of a load calculated?

The Dynamic Amplification Factor (DAF) is calculated by comparing the maximum dynamic response of a structure to the static response under a given load. It is typically determined using the formula DAF = Maximum Dynamic Response / Static Response. This involves analyzing the system's behavior under dynamic loading conditions, often using methods such as time history analysis or frequency response analysis. Factors like the frequency of the load, the natural frequency of the structure, and damping characteristics are critical in this calculation.
