摘要
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.
In order to meet the special demand of protection work,a new structural type of composite double layer cylindrical shell was put forward.The composite shell,which composed of spatial latticed shell structure and steel-concrete composite slab,the former is covered by the later,is a kind of hybrid structure.With all merits of the latticed shell and the composite slab,the composite shell＇s anti-detonating property improves obviously.To instruct structure design and test,the nonlinear property of new type of composite latticed shell is analyzed based on spatial integral action by FEM software ANSYS.The result of analyses shows that the new type of composite shell is an excellent system for protection structure because of its prominent mechanical property.
