单盘浮顶罐浮顶抗震强度及稳定性分析

Floating Roof Seismic Intensity and Stability of Single-deck Floating-roof Tank

浮顶罐浮顶在地震力作用下可导致破坏,本文对单盘浮顶的强度及稳定性进行了分析,得出了浮顶破坏的先后次序。提出通过保证浮顶导向孔与导向杆之间的适当裕度,来满足浮顶的抗震要求。

Floating-roof of floating-roof tank can suffer destruction under earthquake condition. The paper analyzes the strength and stability of single-deck floating roof, gets the failure sequence,proposes to meet the seismic requirements for floating roof by ensuring the appropriate margin between the floating top guide hole and the guide rod.
