The seismic response on linear viscous damping energy dissipation frame structure is studied. In the vibration equation of seismic action, the damping matrix is not orthogonal to vibration mode of the frame structures installing linear viscous damper. Therefore, the traditional mode decoupling method is no longer suitable for the solution of the vibration equation. The direct integration method of state equation is adopted, by which the seismic response is researched of the frame structure installing linear viscous dampers, and the influence of the arrangement of the dampers on seismic response is investigated. The result indicates that the viscous dampers in the structure should be arranged in structure continuously and uninterruptly, the storey drift angle may be decreased significantly when the dampers are installed in structure continuously, and the damping effect is more significant when viscous dampers are arranged in structure continuously and uniformly. Besides, it is presented that the damping coefficient of damper in each storey may be optimized on the basis of the storey drift angles of the frame structure, and the optimum formula of the damping coefficient of damper in each storey is developed.
