LAEDE arries out vibration monitoring that serves as a basis for assessing user comfort, structural safety and obtaining the modal properties (natural frequencies, vibration modes and damping) in civil structures such as bridges, viaducts, buildings, bleachers, tracks, and so on. The excitation of the structure can be environmental or forced and accelerometers positioned at strategic points of the structure are used for measurement.
The analysis is carried out by the IEME Brazil team of engineers, using the Operational Modal Analysis (OMA) and the Classical Experimental Modal Analysis (EMA), respectively.
Noise measurements are performed for environmental control, where levels are compared with standards and / or with local or state regulations for population comfort. Additionally, they serve as input for acoustic projects, such as noise barriers along railways and highways. For acoustic projects, IEME Brasil elaborates mathematical models for calculations and solutions.
