In structural applications, beam is one of the most common structural members that have been considered in design. For the last three to four decades mechanical vibrations have been recognized as a major factor in the design. The present work particularly deals with dynamic analysis of lengthy uniform thin-walled uniform I-beams, and the analytical model developed by Lee and Kim [13] is taken and the dynamic behavior of a thin-walled I-section composite beam is studied in detail. Equations of motion are derived from Hamilton's principle. Numerical results are obtained for thin-walled composite beams addressing the effects of fiber angle and boundary conditions on the vibration frequencies and mode shapes of the composites. Using ANSYS 15.0, the modal analysis are carried out and presented in graphical form. Compared to the steel beam, the composite beam has frequency that are much satisfied, The results show the stacking sequence and fibre angle orientation strongly affects strength of composite I-beam.
