本文采用有限元法分析扁球形钢筋混凝土安全壳顶盖在飞机轴对称撞击下的弹塑性动力响应,并以飞机撞击的最大荷载值对结构作了静态分析,编制了NAP程序,给出结构塑性区扩展情况及弹性和弹塑性响应曲线。
In this paper, the elasto-plastic dynamic response of the spherical cap reinforced concrete containment roof under the axisymmetric impact of the aircraft is analyzed by the finite element method. The static analysis of the structure is carried out with the maximum load value of the aircraft impact, and the NAP program is compiled to give the structural plasticity. Zone expansion and elastic and elastoplastic response curves.
