Modal analysis of concrete bridge decks subjected to free vibration

This paper reports a brief study on free vibration dynamic analysis for determining vibration parameters such as natural frequencies and mode shapes for two selected bridges in Johor. The vibration parameters for these bridges are studied using finite element analysis software package ANSYS 6.0. A t...
