Abstract
The increasing development of algorithms for the assessment of structural modal characteristics stems from continuous improvement in vibration tests and computational processing capabilities. However, the identification process of deformable dynamic systems occasionally demands high computational costs. Nevertheless, with the increasing expansion of high-speed broadband internet, the concept of web application becomes a prevailing alternative. This paper presents the free web application Midas (Modal Identification of Deformable Systems), which is implemented in Java and applied to structural modal identification. This procedure is performed via the internet using data gathered from dynamic measurements. Available technologies and web development tools such as JavaServer Pages and JavaServer Faces are used to implement Midas. For the dynamic treatment of the vibration data, two identification techniques are used – the random decrement method and the Ibrahim time domain method. In order to evaluate the developed web application, two experimental applications are explored.
