Mаss variation technique for specifying parameters of the vibration method dynamic model
Abstract: It is often quite a multi factor task to determin e a stressed state of structures under operation. One of the methods that allow s solv ing this task for frame structures is the vibrati on method based on the dependence of natural lateral vibration frequency of a frame structure rod on a longitudinal force in it. The main idea of apply ing the vibrati on method is to determine the parameters of the accepted dynamic model – an effective rod length and the coefficient s of elastic fastening of boundary points. F or determining these parameters a technique of an additional loading and additional bonds were developed by the scientists of the Central Research Institute of Building structures in the 70-s of the last century. But these methods were not widely used because of the complexity of their in-situ application. The paper presents the basic theoretical principles of another technique for specifying parameters of the vibrati on method dynamic model , that is the mass variation method. That is the simplest method in terms of its practical application and it provides a sufficient accuracy of the vibrat ion method.
Keywords: a vibrat ion method, a dynamic model, a mass variation method.
