Dr. Norberto Rojas gave a lecture on the Sciences of Structural Engineering and Earthquake-Resistant, in which he recommended the formulation of an urban planning plan in the Dominican Republic

Engineer of the INTEC affirms in RD could occur earthquake greater than seven degrees

SANTO DOMINGO.- The Hispaniola Island es highly vulnerable telluric movements. In 2010 an 7.3 earthquake on the Richter scale devastated much of the Haitian territory and left an estimated 300 thousand dead.

Might Dominican Republic, located in the eastern part of the island, suffer the occurrence of an earthquake of equal magnitude. On that subject we talked with the doctor in structural engineering Norberto Rojas.

What are the data that seismic engineering offers civil engineers to better build buildings?

La seismic engineering has developed as a branch of engineering that study el efecto of the earthquakes in the civil infrastructure and how to mitigate o reducir that damage due to this phenomenon. It encompasses multidisciplinary efforts of various branches of science and engineering (geology,seismology, geotechnics, Structures engineering, etc.) whose main objective is to design, build y maintain structures that resist that earthquakes safely and in full compliance with the design and construction regulations.

What is the probability that a major earthquake will occur in the Dominican Republic in the future?

The island of Hispaniola is located on the edge of interaction between North American plate and the plate of the Caribbean, which causes a Subduction zone. This causes the whole island to be considered as high seismic risk. In addition, inside the island there are 13 geological faults , which according to experts have the capacity to generate earthquakes de magnitude seven And older.

If we look at the record of the main seismic events occurring in Hispaniola, it can be concluded that at any moment an earthquake of magnitude greater than seven can occur and therefore, the probability of the occurrence of an earthquake in the eastern part of Hispaniola (Dominican Republic) is very high.

What are the regulations that architects and engineers must follow when constructing works such as schools, shopping malls, hospitals, government offices and others to which several people have access?

La regulations in force in the Dominican Republic for the design of earthquake-resistant structures is the Regulation for the Analysis and Seismic Design of Structures R-001, promulgated under Decree number 201-11 of the 2011 by then President Leonel Fernández Reyna. Said regulation establishes the minimum requirements that must be met by any building to be considered earthquake-resistant.

In the Dominican Republic have measures been taken to adapt the civil buildings to the seismic risks that the island has?

Yes. Currently the Ministry of Public Works and Communications requires that any "new" structure to be approved for construction purposes, must be deposited in that unit documentation with which it can be validated that the structure complies with the requirements of the seismic code.

In addition, for existing structures that are going to be subjected to improvements and that do not have construction plans or prior licenses, the Ministry requires a complete structural evaluation that includes a series of tests and tests, which validates whether the structure is suitable for resist seismic loads according to current regulations. Otherwise, this structure must be reinforced to make it "safe" according to the regulations.

Which are the most vulnerable zones to earthquakes in the country?

If we consider that the Hispaniola has an extension of about 72,000 km2 and the number of faults that we have both inside and outside, we would have to conclude that the whole island has a high seismic risk.

What can be done to stop construction without measures, regulations and control built by citizens, mainly in urban areas?

To stop constructions type informal or illegal, there must be more supervision by the State or its dependencies, as are the municipalities. In addition and for me the most important thing, make aware to citizenship of riesgo which represents a structure that is not designed and built by trained engineers.

Does the country require a national urban planning plan and why?

Of course. This is because it is necessary classify the territory based on soil type, which has proven to be one of the main factors that influence the good or poor performance of structures during earthquakes around the world. In turn, it is necessary to establish zones in which, for example, the maximum number of floors per building, etc., is controlled.

What will be the capacities that will show the graduates of the Master of Science in Structural Engineering and Earthquake-Resistant?

The graduates of the Master's in Structural Engineering and Earthquake-Resistant of the INTEC are professionals with a high degree of sensitivity and social responsibility, great work ethic, with a solid formation for the analysis and above all oriented to the solution of structural problems.

This program has focused on developing a professional with a solid ethical training y oriented to the investigation that will allow you to face complex structural problems and solve them successfully. In addition the graduate of the master's degree will have the following competences:

  • Ability to solve complex structural problems through the use of advanced techniques and specialized analysis softwares.
  • Ability to evaluate existing structures by using the most up-to-date techniques in earthquake-resistant analysis.
  • Ability to obtain efficient solutions through the use of structural systems that produce the most appropriate solution from the point of view of safety and economy.
  • Propose, implement and evaluate security measures related to the operational management of structural systems.
  • Create, direct and coordinate research groups in Structural Engineering and Earthquake-Resistant in order to promote new projects associating human and material resources of public and private institutions.

This mastery is the first fully virtual program in Structural Engineering and Earthquake-Resistant in Dominican Republic y Latin America. Among the benefits that your students can count on are:

• Professional certifications.

• Specialized software seminars.

• Teachers with doctoral training

• International program

• Flexibility in elective subjects

• Link to the Research Group in Structural Engineering and Earthquake-Resistant through the Research Lines
