Optimal analysis and experimental study on structures with viscoelastic dampers
In this paper, the synthetic optimization method of the structure with VE dampers is introduced. An eight-story structure with VE dampers is analyzed. Through a shaking table test about a three-story structure with VE dampers, the analysis results of the simplex method are verified. Some conclusions can be obtained through analytical and experimental study on the structure with VE dampers: (1) Optimization design of the structure with VE dampers can be achieved by the simplex method, i.e., the parameters and the location of VE dampers can be designed optimally in view of the fixed objective function and constrained conditions. (2) VE dampers can increase the stiffness and the damping of structures, and reduce the seismic responses of structures effectively. (3) When the structure is subjected to different earthquake excitations, the optimal location results are consistent. (4) Rational location of VE dampers can reduce seismic responses of structures effectively due to the good distribution of stiffness and damping of structures. On the contrary, if the dampers are installed freely, the stiffness and the damping of structures may be increased irrationally, which will lead to the bad seismic mitigation effect. (5) Increasing the number of VE dampers does not imply better shock absorption effect. The shock absorption effect of VE dampers is best when the location of VE dampers is optimal.
