측정변형율에서 동적변위 식별

초록

A simple algorithm is proposed for computing dynamic displacements from measured dynamic strains. A beam theory is basically applied to relate the curvature and strain. Modal superposition using general coordinates are used to relate the curvature and displacement. Theoretical mode shapes of some of the lowest modes are used in the formulation. For the current study, only beam-type structures are tested. However, the idea may be easily extended to other types of structures.
