Researcher of the INTEC dictates conference in MIT

SANTO DOMINGO. -The teacher Kalil Erazo of Engineering Area of Instituto Tecnológico de Santo Domingo (INTEC) presented at MIT (MIT) results of its research en structural and earthquake-resistant engineering. The presentation was carried out within the framework of the international conference of Engineering Mechanics Institute of the American Society of Civil Engineers (ASCE), which took place from the 29 from May to the 1 in June in Boston (United States).

In the presentation entitled "An Output-only Bayesian Identification Method for Nonlinear Stochastic Systems" Dr. Erazo presented a method developed by the research group in Structural and Earthquake-resistant Engineering, which he leads together with other INTEC teachers, used to estimate properties dynamics of civil infrastructures subjected to strong earthquakes using structural monitoring.

El structural monitoring consists of the use of measurements of comportamiento of a civil infrastructure (obtained through instrumentation) to reduce uncertainty in the estimation and prediction of structural performance, and has the advantage that the real properties of each particular structure are used.

The use of structural response measurements significantly improves the analysis accuracy, especially in cases where the behavior is characterized by incursions to the inelastic range. During the presentation, the implementation of the method developed using large-scale experiments carried out in California, United States, on a vibrating platform used to simulate earthquakes was highlighted, which demonstrated the effectiveness and precision of the method.

The results of Dr. Erazo's research will serve as basis to develop tools that allow assess the state of damage of the civil infrastructure subject to earthquakes quickly and effectively. These tools will help in making decisions about the efficient use of resources before and after extreme natural events, reducing the vulnerability of civil infrastructure and disaster risk, and helping to improve the resilience of the built environment.

Dr. Kalil Erazo is a research professor at INTEC and a visiting researcher at Rice University, United States. His research is funded by INTEC and the National Fund for Innovation and Scientific and Technological Development (FONDOCYT) of the Ministry of Higher Education, Science and Technology (MESCYT).
