某厂房悬挑结构抗设计基准飞机撞击分析

Analysis of the building cantilever structure against the impact of design basis aircraft

某核电厂房悬挑结构具有抗设计基准飞机撞击的功能需求,以普通飞机CESSNA 210和LEAR JET 23为研究对象,考虑硬飞射物和软飞射物的撞击效应。对于硬飞射物,需要确定结构抵抗飞射物穿透的最小厚度;对于软飞射物,需要确定撞击区域、撞击荷载值、效应组合等,采用核电厂相关配筋计算公式,得出配筋包络值,保证悬挑结构在撞击效应下的安全性和稳定性。

The cantilever structure of a nuclear power plant has the function against the impact of design basis aircraft.Takes the ordinary aircraft CESSNA 210 and LEAR JET 23 as the research objects,which considers the impact effects of hard and soft missiles.For hard missiles,it is necessary to determine the minimum thickness of the structure to resist the penetration of the missile;for soft missiles,it is necessary to determine the impact area,impact load value,effect combination,etc.,and use the relevant nuclear power plant reinforcement calculation formula to obtain the reinforcement envelope value,which ensures the safety and stability of the cantilever structure under the impact effect.
