| 摘 要： | 首次建立了动力问题分析的等效弹性模量修正公式,对以受拉二力杆单元取代索单元的准线性结构进行位移分析,并与原索膜结构时程分析法的数值结果进行了比较.结果表明,采用以模量修正的受拉二力杆单元取代索单元的准线性结构精度良好,为类似动力问题分析的等效线性化法奠定了理论基础.

| Abstract: | A formula for revising elastic modulus that is applied to dynamic problems is set up for the first time and calculational values are compared between the quasi linear structure with tension-only spars and the nonlinear structure with cables.The results show that the quasi-linear structure in which cable elements are replaced by tension-only spar elements has a high precision by means of revising elastic modulus,and the formula for revising elastic modulus in the process of vibration lays the theoretic foundation of similar nonlinear dynamic analysis. |
