| Abstract: |
| Considering effect of damping ratio and frequency ratio to vertical amplitude of block foundation under dynamic action, this paper adopts calculating mode of mass-spring-damper and mass-spring to make account and analysis on the assumption of damping ratio and frequency ratio ,then provides the range of damping ratio and frequency ratio by using two modes to calculate vertical amplitude of block foundation under dynamic action. |
| Key words: block foundation vertical amplitude damping ratio frequency ratio calculating mode of mass-spring-damper calculating mode of mass-spring |
