利用有限元理论，分别确定了复合壳体结构中各部件的质量矩阵、刚度矩阵及阻尼矩阵，并对其进行了静力学与动力学计算，结果证明内衬三维波纹钢板复合壳体结构与普通混凝土壳体结构相比，其结构承载力有了较大的提高。 - Compared with the results of the ordinary shell structure , the ribbed shell structure can improve the structural bearing capacity , so the theory of the stretching finite element analysis about statics has been extended successfully and also applied to calculation of stretching dynamics . the result indicates that the mechanics impact is of much distinctness compared with ordinary one
成功的将静力学中的弹塑性有限元理论扩展并应用于复合壳体的弹塑性动力学计算中，结果表明利用弹塑性理论计算出的结果更精确，与普通混凝土壳体的比较后可以看出，复合壳体的力学效果非常明显。 - This paper focuses on the research of the stress mechanism of the ribbed shell structure in statics , dynamics and under the explosive load on the basis of the engineering practice of cave depot of single aircraft . in this paper , according to the classical shell theories , the basic differential equilibrium of the ribbed shell structure and the finite element analysis of 3d rippled plate are established , in which the function of annular ribs reinforcement bars and 3d ripped steel plates are distributed in the range of the steel , and the functions along the longitude direction of tension , bending , and torsion are neglected ; applied with dynamic analytical theory , the dynamic model of ribbed shell structure and the analytical theory model of elastic - plastic are set up ; the triangle series method is used to solve the displacement and stress under the distributed load and the concentrated load of the ribbed shell structure
本文以军用机场地面单机掩蔽库工程建设为工程背景，首次对内衬三维波纹钢板混凝土拱型复合结构的受力机理进行了静力、动力和爆炸荷载的分析研究。根据将横肋、钢筋及三维波纹钢板的作用均匀分布在壳体范围内的情况，忽略横肋、钢筋及三维波纹钢板沿壳体母线方向的抗拉、抗弯及其抗扭作用，首次推导出了内衬三维波纹钢板混凝土壳体的微分平衡方程，建立了有限元计算模型，并采用三角函数法，求解了三维波纹钢板混凝土拱型复合结构在分布荷载和集中荷载作用下的位移响应和应力响应，并与普通壳体进行了比较。
