Study on Concrete Pier Impact Performance after Implementing Equal Cross-Section Stainless Steel with Protection from Closed-Cell Aluminum Foam

Figure 13

Time history curve of the top displacements of the specimens with the drop hammer lifted to 4 m and 10 m, respectively. In the figure, diameter 16 has a 50 mm closed-cell aluminum foam application and diameter 20 has a 100 mm closed-cell aluminum foam application.
