Introduction In mechanical engineering, modal control is widely used to assess civil engineering structures by means of vibration measurement.
More generally, the process of finding a model from the data is called system identification, originating from the domain of electrical engineering.
Moreover since it is used successfully in civil engineering applications (ambient or natural excitation for bridges and buildings) it begins to be introduced in mechanical engineering applications like rotating machinery or in-flight testing.
Table 1 tries to resume important drawbacks and interesting advantages dealing with the OMA method: Drawbacks • Unscaled (non calibrated) modal model • Some a priori knowledge is advantageous • New technique to most engineers • Large time histories might be required: more data handling capacity is needed (higher computational cost) Advantages • No elaborate fixture of shakers and transducers • Short setup time • No crest factor problems as when using hammers • No potential destruction of structure • Modal model represent real operating conditions • True boundary conditions • Actual force and vibration levels • Ambient or unmeasured excitation required • No interference or interruption of daily use Table 1: Benchmark of operational modal analysis Image processing method for dynamic parameter extraction A way to detect moving objects is by investigating the optical flow which is an approximation of two dimensional flow field from the image

At the same time , its bearing capacity has not significant reduction .Ductility is a measure of the ability of engineering structure seismic performance.
Which indicates that the existence of initial axial force decreases the reinforcement effect, and the greater the initial axial force is, the greater the effect, and hence needs special attention in engineering practices.

The lack of scientific or engineering knowledge available during the construction of these structures lead to the development of a unique group of architects and builders who were frequently trained in Italy and relied solely on empirical methods or traditional “rules of thumb”.
An effort of prediction of the development of engineering conditions was based on static model of the structure of the Saint Vitus Cathedral using methods of numeric modeling in the last phase of projects execution.
The sensitivity and long-term stability of developed instrumentation tools based on the FBG’s are on the testing in the Underground Research Centre Josef, which is the facility of the Faculty of Civil Engineering of the Czech Technical University in Prague.
