Analysis of Free Vibration of Structures With Discrete Elastic Supported and Modifying of its Simplification Mode

In this paper,the free vibration problems of structures with discrete elastic supported are analysed,and it is pointed out that unadvisability of using eguivalent rigid simplification mode,by analysing the continuous beam and circular ring beam both with biscrete elastic supported.Finally,a renew calculating simplification mode is suggested by modefying the equivalent rigid simplification mode.
