Tóm tắt báo cáo

Multispan continuous beam-like structure, usually employed in the bridge and mechanical engineering, is a subject of widespread literature. This report is devoted to apply the dynamic stiffness method for free vibration of multispan continuous beams with cracks. In this study, the free vibration equations of the cracked beam estbalished in the frequency domain are similar to the three moment equations obtained in static analysis of multispan continuous beam. This provides a simple tool for modal analysis of the beam with multiple cracks.
