Abstract:
The parameter optimization of a new energy dissipation device based on hollow floor slab was discussed. The nonlinear motion equation of the controlled structure with the device based on the Lagrange variational principle was treated using statistical linearization method. Then, taking the device as object, the structural horizontal displacement variance minimization was taken as the optimization criterion, the parameter optimization problem of the device was studied using the fixed point theory. The Monte Carlo simulation method was used to compare the damping effects of the controlled structure under different conditions, and the effectiveness of the proposed method was verified. The results show that the proposed method can be used to optimize the parameters of energy dissipation device effectively, and provides the basis for the application of the device.
