基于防护工程需要,提出一种新型组合双层筒壳结构形式——在空间网格结构筒壳上覆盖钢板—混凝土组合板形成空间结构和组合结构的杂交结构.网壳结构整体稳定性好、空间刚度大,组合结构抗冲击、延性好,两者有机结合可使抗爆性能大大增强.为指导试验研究和设计计算,利用ANSYS对新型组合壳体结构进行了基于空间整体作用的全过程非线性分析.分析结果表明,新型组合壳结构受力性能优越,是一种优良的防护结构形式.
Based on the needs of protection engineering, a new type of combined double-layer cylindrical shell structure is proposed, in which the steel-concrete composite plate is overlaid on the space grid shell to form a hybrid structure of space structure and composite structure, Space stiffness, combined structure impact resistance, good ductility, the combination of the two can make the antiknock performance greatly enhanced.In order to guide the experimental research and design calculations, the use of ANSYS for the new composite shell structure based on the overall effect of space-based non-process Linear analysis.The analysis results show that the new type of composite shell has superior mechanical properties and is an excellent protection structure.
