Research on Verification of the Pile Types of a Port Structure by Using Impact Vibration Test in Vietnam

The vibration impact test method has been studied very interestingly and is applied to check and evaluate the health status of the pile types of a  port structure. The data collection technique for building a theoretical dynamic analysis model depends not only on the influence of the boundary conditions of the passing pile foundation and its load but also on the size of the berth by the scale and port structure classification. The paper reviews and analyzes the research influence of this issue. The paper also presents a simple formula to determine the natural design frequency of the segment of the pile-type port structure through the natural frequency of a typical transverse frame in Vietnam. Calculating the natural design frequency of a typical horizontal frame diagram is simple and quick, even if the original design document has no design records. From this, it is possible to determine the design natural vibration frequency of the whole berth segment and predict the frequency range measured if the pile-type port structure usually works.
