annular ribs meaning in English
纵向花纹
Examples
- 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。
