There is a critical value for each earthquake record. When the structural period is longer than it,the energy input and dissipate curve with different damping characteristics are different very much.

- 對于每個(gè)地震記錄,有一個(gè)臨界值,體系的固有周期小于此值時(shí),不同阻尼模型的能量輸入、阻尼能量耗散時(shí)程曲線(xiàn)值無(wú)大差異,當周期大于此值時(shí),不同阻尼模型的能量輸入及阻尼能量耗散時(shí)程曲線(xiàn)差異較大。
