Robust Post-Accident Reconstruction of Loading Forces

The paper presents a novel methodology for robust post-accident reconstruction of spatial and temporal characteristics of the load. The methodology is based on analysis of local structural response, and identifies an observationally equivalent load, which in a given sense optimally approximates the real load. Compared to previous researches this approach allows to use a limited number of sensors to reconstruct general dynamic loads of unknown locations, including multiple impacts and moving loads. Additionally, the problem of optimum sensor location is studied.
