Research on Theory and Method of Load Analysis of Pipe Structure Based on Equivalent Acceleration RMS. The simplified calculation method of equivalent white noise excitation which directly obtains the root mean square of its single modal region from the structural vibration response power spectral density is provided. It provides a basis for the rapid processing of the measured data in the pipeline structural load analysis. In the end, the actual example is used to demonstrate the validity of the equivalent load analysis and its calculation method. This method has important guiding significance for the design and evaluation of the pipeline structural load.
