ANALITIČKO I EKSPERIMENTALNO ISPITIVANJE STAROGA MOSTA U MOSTARU.

The paper presents the investigation taken on Old Bridge in Mostar. In order to get cognitions about the seismic stability of the bridge, experimental testing was done by the ambient vibration method to define dynamic characteristics - own frequencies, mode shapes and damping coefficients. Numerical analysis of the bridge was done in Tower 3D program package at which different cases of overloads were taken in consideration. Comparing results and dynamical characteristics of the bridge obtained by experimental investigation with performed analysis of the mathematical model of the bridge we can see the compatibility. The obtained results present a qualitative base for performing further investigation of this respective monument. [ABSTRACT FROM AUTHOR]
