Abstract Combined with equivalent linearization method, the random factor method was applied to multi-degree-of-freedom nonlinear structure. The yield displacement, area, pressure and height of isolation bearing were chosen to consider the randomness of structural mass. The relationship between four basic random variables and structural stiffness and mass was established by improved method. The computational expressions of the structural displacement response were deduced by using the algebra synthetic method. Then author analyzed a long-span isolated structure based on improved method and obtained some beneficial conclusions.
