摘要:
根据拱在拱平面内和拱平面外振动的不耦合条件,提出了独立求解频率和振型的方法,采用曲梁有限元法分析拱的振动特性,并编制了计算程序。通过一具体实例,将本程序在 AppleⅡ微机上运行,并与 SAP5程序计算结果作了比较,符合较好。
Abstract:
This paper presents a method for solving the normal mode of vibration isolatedly according to the uncoupling condition of vibrations inside and outside the arch plane.The finite element method for curved beam elements is adopted to analyse the dynamic characteristics of arch structures and the calculating program is made.The results obtained from Apple Ⅱ microcom- puter are compared with those from SAP5 program by an example,and are in good agreement.
