筒体-框架结构的动力特性简化分析

Simplified analysis for dynamical characteristics of tube-frame structure

通过借鉴过去对筒体 -框架结构的动力特性的研究工作 ,考虑到该结构的实际受力性能 ,提出了一种比较精确和符合实际的计算模型 ;在计算中对传统方法的抗扭刚度系数加以修正 ,计及了芯筒、框架体系自身扭转影响 ,导出了相应的计算公式 ;采用了VisualBasic语言进行全部核心编程 ,获得了比较满意的结果 .

Based on the research works of dynamical characteristics of tube_frame structures, a more precise and realistic calculating model is presented. During the course of the calculation, the torsion rigidity coefficent of the tradional method is amended, and corresponding formulae with consideration of influence,which are produced by the tube sub_structure and frame sub_structure's torsion around theirself centroid axis, are proposed. As an attempt, all the kernel programs adopting Visual Basic language are compiled. Compared with the outcome calculated by the commerce program,the result is satisfied.
