Abstract

Considering the performance parameters of the shaking table and the operability of the shaking table test, then adopting the general similitude law, a sliding base isolation five-story reinforced concrete frame structure and roof of the additional layer model was designed. A double deck chassis design was adopted. Model reinforcement area was made equivalent. As much as artificial quality was purchased. Three methods were used to calculate the model including the artificial mass law, the gravity forces-neglecting law and not enough artificial mass law. The results of the study show that: the weight set is reasonable. The not enough artificial mass law is appropriate and feasible. It can reduce the gravitational distortion effect of the model and control the acceleration amplification factor within reasonable limits, to reduce the noise influence and experimental error.

Key words
