Numerical, analytical and experimental prediction of force of solid cylindrical steel beam subjected to axial tension force using vibration technique

Vibration method is widely used to estimate axial force of string and beam element by using natural frequency. This paper demonstrates the use of vibration method to estimate the force of beam element. The specimen has ratio of length to diameter of 79.68. The specimen was subjected to the axial tension which was applied increasingly from 1000 N up to 20000 N. Numerical and analytical calculation modeling were used to predict the natural frequency of the solid cylindrical steel beam. Experimental research was also used to verify the value of natural frequency of the specimen. The results showed that the natural frequency of analytical and numerical calculation is in line with experimental results in the first mode of natural frequency.
