| Abstract: | Inspection items and method of marine radar steel tower were discussed.Some items, such as gradient of slope, thickness of anti-corrosion coating, dimension of components, connection quality of welding and bolt were inspected and dynamic characteristic of the radar tower were tested in the field through environmental excitation.Then, the finite element model of the radar tower was developed and analyzed through the ANSYS software based on the data from field tests and the design documents. It is shown that ... |
