A novel dynamic load identification method based on improved basis functions and implicit Newmark-β for continuous system with unknown initial conditions

For structural design and optimization, precise knowledge of dynamic load on structures is essential. However, load identification can be sensitive to the initial conditions, and even small variations can lead to inaccurate results. The existing load identification methods always assume that the str...
