ANALYSIS OF HIGH-FREQUENCY POWER FLOW IN PLANAR FRAMED STRUCTURES

摘要：

Using the high-order Love rod theory and Timoshenko beam theory to model the axial and bending waves in structural members,this paper extends the method of reverberation-ray matrix (MRRM) for the analysis of high-frequency power flow in planar framed structures.The analytical formulation without involving exponentially growing functions is derived,from which the power flow at any cross-section or joint can be calculated numerically.The derivation of the formulation indicates that the MRRM is an analytical method has advantage of uniformity.It is applicable to high-frequency analysis because high-order rod,beam theories are used,and the exponentially growing functions are avoided from the formulation.
