Abstract
The problem of dynamic analysis of truss structures based on probability is studied in this<br />paper. Considering the randomness of both physical parameters (elastic module and mass density) of<br />structural materials and geometric dimension of bars respectively or simultaneously, the stiffness and mass<br />matrixes of the elements and structure have been built. The structure dynamic characteristic based on<br />probability is analyzed, and the expressions of numeral characteristics of inherence frequency random<br />variable are derived from the Rayleigh
