| Abstract: | Two ways of the environmental random excitation method and pulse excitation method are used to test the damaged pier by dynamic test technique. Through the comparison of the pier theoretical frequency calculation value with the pier measured frequency value, and lossless pier frequency value with the damaged pier frequency value, a comprehensive evaluation is conducted on the overall performance of the damaged pier, so a rapid detection method for the damaged pier is explored. |
