The static characteristic of CFRP cables is analyzed and a series of advantages of CFRP cables are found when comparing with steel cables. The error of using tangent modulus for CFRP cables with super great spans is very small. The equivalent modulus of elasticity of CFRP with super great spans cables is much higher than that of steel cables and the cables are longer,the difference of them is bigger. The ultimate length of CFRP cables is five times of that of steel cables or if their carrying efficiency is fixed on a certain value,the span of CFRP cables is five times of that of steel cables. The deadweight stress in CFRP cables is relatively small and when the length of CFRP cables is super great,the proportion of carrying outside load with super great spans is still high.

The optimization of buckling-prone cylindrical hollow tubes and tubes with porous material cores is investigated. The load-carrying efficiency (the ratio of the critical load to the weight) and the buckling modes of cylindrical shells with porous cores subject to axial compression are studied. The parameters, such as the shell thickness and the relative density of porous core, which influence the structural load-carrying efficiency and the buckling modes, are optimized. A parametrical finite element modeling method and an optimization program written in PCL language of MSC/PATRAN are presented. The numerical results for the buckling analysis and optimization of a specific cylindrical shell structure show that increasing the shell thickness can improve the load-carrying capacity and the efficiency for thin-walled hollow shells, but the load-carrying efficiency may decrease when the thickness is increased to a threshold. Porous cores can increase the load-carrying capacity and efficiency greatly, and optimizing the shell thickness and relative density of the porous core can improve the load-carrying efficiency further.

研究了在轴压载荷作用下圆柱壳结构的失稳模态和结构承载效率,分析了空心圆柱壳厚度对失稳模态和承载效率的影响,以及圆柱壳填充轻质芯体对提高承载效率的作用;研究了圆柱壳结构的基于参数化建模、稳定性分析以及承载效率优化设计的一体化方法,并基于商用软件PATRAN的PCL语言予以实现。针对特定夹芯圆柱壳结构的稳定性分析和优化表明,空心薄壁圆柱壳结构在轴压载荷作用下容易失稳,结构承载效率低。适当增加壳体厚度,不但提高抗屈曲能力,而且也提高了结构承载效率。但厚度增加到一定限度后,进一步增加壳体厚度会提高结构的失稳荷载,但承载效率下降。利用泡沫状材料填充薄壁圆柱壳结构可以提高圆柱壳的结构抗屈曲承载能力和承载效率。通过优化壳体壁厚和芯体材料的相对密度,可有效地提高结构的承载能力和承载效率。
