An evaluation study on the cumulative impact damages of reinforced concrete piers based on modal frequencies
Source abstract
Abstract
Abstract In this study, in order to accurately evaluate the cumulative impact damages undergone by concrete piers, lateral impact testing of reinforced concrete piers was carried out using an ultra-high drop hammer test system to impose damages. Then, modal frequency tests of the impacted piers were conducted one by one. It was found that, according to such parameters as the reinforcement stress and strain levels, crack widths, column top displacements, and so on, which had been obtained from experimental results, and based on the existing research results and codes, the evaluation criteria of the cumulative impact damages of reinforced concrete piers based on modal frequencies could be proposed for the bending failure components. In addition, it was confirmed that when the aforementioned evaluation criteria was adopted, timely nondestructive testing could be effectively conducted for damaged piers, and the status of the piers could be quickly determined in order to ensure the safety of passing vehicles.
