Abstract：The method of hierarchical visualization and visualization fusion of vibration-based structural damage detection is put forward creatively. This method can display the structural damage information visually using visual images. Taking the simple beam for example, the hierarchical images are obtained using four currently maturely applied indexes for the conditions of one damage and two damages, respectively. The hierarchical images are fused with auto-adaptive weighted least squares method, which can solve the weakness that the visual image of a single index only contains limited damage information. So, the results are more accurate. The visualization of vibration-based structural damage detection will provide a new display platform for damage detection and structural health monitoring.
