압축하중Wn : 고유진동수W : 압축하중이 작용할 때의 진동수 ; The finite element methods are used for the study of the relationship between elastic critical load and the natural frequency of the bars with partially fixed ends.The relationship beteewn two eigenvalues(elastic critical load and natural frequency)is estabilished by calculating the corresponding values of (W/Wn)2 through changing (P/Pcr) values.The results show that the relationship between the elastic critical load and natural frequency of a partially fixed flexural member can be expressed by P/Pcr+( W/Wn)2=1.0 without regard to fixities at member ends. |
