| Abstract | The paper focuses on the use of heterogeneous visual data sources in order to support the analysis of three-dimensional dynamic movement of a flexible structure subjected to an earthquake ground motion during a shake table experiment. During a shake table experiment, a great amount of data is gathered including visual recordings. In most experiments, visual information is taken without any specific analysis purpose: amateur's pictures, video from a local TV station, analog videotapes. In fact, those sources might be meaningful and could be used for subsequent spatial analysis. The use of photogrammetric techniques is illustrated in the paper by performing a post-experiment analysis on analog videotapes that were recorded during a shake table testing of a full-scale woodframe house. |
