The random response characteristic of weak nonlinear structure under biaxial earthquake excitation is investigated.
The structure has a SDOF (single degree of freedom) with supporting braces and viscoelastic dampers.
First, it adopts integral constitutive relation and establishes a differential and integral equations of motion.
Then, according to the principle of energy balance, the equation is linearized.
Finally, based on the stochastic averaging method, the general analytical solution of the variance of the displacement and velocity response and the equivalent damping is deduced and derived.
At the same time, the joint probability density function of the amplitude and phase and displacement and velocity of the energy dissipation structure are also given.
The dynamic characteristics of a structure with viscoelastic dampers are determined as a solution to the variance of displacement response, so the equivalent damping is taken into consideration as a solution to replace the original nonlinear damping.
It means it has established a unified analytical solution of stochastic response analysis and equivalent damping of a SDOF nonlinear dissipation structure with the brace under biaxial earthquake action in this paper.
