核化工厂房设备室企口形盖板受力分析及设计建议
|
摘要
为满足辐射防护要求,核化工厂房设备室顶板需大量使用企口形盖板。在盖板设计中应考虑竖向荷载、地震荷载、检修荷载等各方面因素。本文通过有限元软件ANSYS建立T形及Z形盖板模型并进行了计算,分析了不同工况下企口形盖板的承载力和位移分布规律,为设备室盖板的设计、施工提出了几点建议。
Rabbeted capping plates are widely used in the roof of equipment cells in order to meet the requirements of nuclear radiation protection.The key considerations in the design include vertical load,seismic load and repair load.This article establishes Tshaped and Z-shaped plate model via FEM software(ANSYS),analyzes the bearing capacity and displacement distribution in different load cases,and provides recommendations to the design and construction accordingly.
