The damping force response model of viscous damper is the basis and basis for analyzing its seismic performance. Hole shrinkage force is an important component of damping force. Based on the experimental data and dichotomy, a hole shrinkage formula is proposed for the double-rod viscous viscous damper, which is used to correct the theoretical model of damping force and to verify the experiment. The results of the verification show that the theoretical model of the modified damping force is in good agreement with the experimental results, with good accuracy and high precision. The application of the hole shrinkage formula and the modified damping force model can shorten the design cycle and reduce the cost , Providing the basis for accurate design and rapid development of damper.
