摘要
本文提出了船舶结构中具有固定系数χ定义的弹性固定端的处理方法,考虑了弹性固定端所连杆件以外的结构对该χ的影响,将其转化成相应的柔性系数α,从而使此类结构完全可用常规的弯矩分配法、位移法或有限元法进行计算。两个算例证明了这种处理方法的精度很高。
A processing method is presented, which can be used for mechanical analysis of ship structures with the elastic fixed ends defined by fixity coefficient χ. Consideration should be given to the influence of structure besides the connected member ij. The fixity coefficient χ can be transformed into a flexibility coefficient a. So that structural analysis can be performed by use of usual moment distribution method, displacement method or finite element method. Two illustration examples are given.
