| 摘 要： | 本文用有限条法分析筒体结构的动力特性,考虑了条元的平面外弯曲刚度,所用的位移插值函数能反映筒体结构的剪力滞后效应。用质量凝聚技巧,使动力分析的自由度数目大为减少。算例表明,本文的方法具有精度高、通用性强、计算量少的优点。

| Abstract: | In this paper, the finite strip method is used to calculate the dynamic properties of framed tube and tube-in-tube structures. The out-of-plane stiffness of the strip and the effect of shear lag of the structures are considered. By using the so called mass condensation technique, the number of the degrees of freedom in dynamic analysis is reduced greatly. Results show that the method proposed in this paper has the advantages of high precision and versatility and less computation. |
