Modal Analysis

The GEA system is the ideal solution for installation in large scale structures, and for implementing this type of monitoring. The highly robust GEA sensors can be installed without the need for additional protection. Furthermore, HubSync allows you to use cables of up to 1 kilometer in length, without needing other amplification systems, and guarantees the necessary synchronism among the various sensors, which in turn ensure that the data being gathered will be suitable for dynamic reports.

Recent laws and technological advances require that both the static and dynamic aspects of buildings be planned and verified. In order to investigate a structure’s dynamic behavior, it is necessary to understand how the structure behaves when subjected to dynamic external forces such as, in the case of buildings or civil engineering structures, the spectrum of seismic responses that is characteristic for the site on which the structure is built; or for certain structures, the effect of the wind. The task here boils down to identifying the relevant main modes of the structure, defined in terms of modal forms (movement of the structure), the structure’s frequencies (which frequencies are associated with which movements), and the damping characteristics that are indicative of the structure’s capacity to dampen the effects of vibrations attributable to external forces. Therefore, the overall behavior of a given structure consists of the combination of its own vibration modes, when subjected to an excitation force. A construction’s civil engineering structure needs to include the planning phase, the experimental verification that allows you to validate the relevant theoretical model, and the post-construction adherence to planning parameters.
The GEA system is a very simple and cost effective solution for gathering the experimental data necessary for verification of the dynamic behavior of a civil engineering structure.
