The goal of the bridge engineer is to design economical structures which are safe, durable and serviceable. Determination of the dynamic response of bridges has been the topic of numerous studies in recent years. Much of attention had been focused on maximum dynamic displacements and moments and on the distribution loads to the floor system which are the information necessary to design for adequate strength. Although humans are subjected to the vibrations of many structures, there is seldom any direct provision in design codes to ensure user comfort and usually impose restrictions upon girder depth-span ratios and upon static deflection-span ratios in the hope that these limits will provide satisfactory dynamic response. Another important concern, the comfort of those crossing the bridges, has received relatively little attention. Transportation agencies do receive occasional comments and complaints from bridge maintenance works, pedestrians and passenger in halted vehicles concerning the vibration of bridges. So, this study is conducted in order to identify the parameters that most affect the vibration of the bridge and to check the response of the MRR2 bridge that had experience a dynamic response whether it is safe or not.
