Motor para caracterizar la capacidad de resiliencia sísmica de edificios


Oferta Tecnológica
Un centro tecnológico andaluz ha desarrollado una nueva tecnología que consiste en un motor de cálculo matemático para caracterizar la capacidad de resiliencia sísmica de edificios construidos con elementos prefabricados y no prefabricados. El sistema permite definir los umbrales de seguridad y rechazar edificios cuyos diseños presentan un indicador de seguridad por debajo de los umbrales establecidos. Se buscan empresas y otras entidades con el fin de establecer acuerdos de cooperación técnica y continuar con el desarrollo de la tecnología.


Engine to characterize the seism-resiliency capability of buildings
An Andalusian Technological Center has developed a new technology consisting in a mathematical calculation engine to characterize the seism-resiliency capability of buildings based on prefabricated and non-prefabricated elements. They are looking for companies and/or other institutions willing to reach a technical cooperation agreement to test and further develop this technology .
A Technological Centre from Andalusia (Spain) has developed this new technology. This Centre works in the field of energy, ICTs and construction, in particular, Energy Efficiency and ICT research. One of the main objectives of the centre is to contribute to the improvement of the Smart Cities design and operation and they are currently involved in international cooperation carrying out serveral projects.
The technology developed by this Technological Centre is capable of performing the analysis of the seism resiliency capability of a building (included those made with prefabricated parts). Basically, the engine allows qualifying earthquake-resistant buildings, and it gives a maximum score to buildings that are better prepared against earthquakes according to seismic hazard in the area to which they belong and their structural design.
This development establishes a graduated scale to measure the earthquake behaviour for each analyzed building, allowing establishing different criteria to design a building. For example, the system will allow defining safety thresholds and rejecting buildings which design presents safety indicator below determined thresholds; the system will also allow estimating the level of damages of a building as a function of the seismic input.
The input data required for the calculation engine to determine the seismic qualification are: the geometry of the building, its general data, structural features (columns, beams, floors, etc.), seismic deficiencies found in the building design, and geotechnical data of the layers of the land on which the building is anchored.
Once the data it´s entered, the calculation engine determines the seismic qualification of the building using the method capacity spectrum, determining the capacity curve of the building and obtaining the point of seismic performance of the building. The engine can characterize the earthquake demand spectrum up to five different renowned seismic regulations: NCSE-02 (Spain), EC-8 (Europe), NCh.433 Of.1996 Modif. 2009 (Chile), SDCB (Japan) and ASCE 7/10 (USA). It also determines the fragility curves of the building depending on the level of assessed damage (small, moderate, severe or complete). Thus it is able to obtain, depending on the point of performance, the level of damage that is estimated to occur in the building for a particular earthquake, defined by its seismic acceleration.
These results allow performing a seismic rating of the building, defined by this calculation engine, due to the absence of a fully-fledged official scale. The scale of seismic qualification developed by this calculation engine is based on a list of letters, which allow qualify the seismic behaviour of the building in the area where it is located and also to provide insight into the quality of the seismic design regardless its location. Based on these two concepts of vulnerability, zonal and intrinsic, a rating scale sets out two letters:
- The first letter indicates the vulnerability of the site where the building is located based on a graded scale;
- the second letter establishes the intrinsic vulnerability of the building, regardless the building location area in, also on a graded scale.

This technological centre is interested in companies working in the construction field or other institutions interested in reaching a technical cooperation agreement to test and apply this technology and also to further develop the model.
Advantages and Innovations:
* The system allows quantifying the resistance of a building under seismic conditions what will provide relevant information to the designers to be considered for the design of buildings in critical areas.
*The system establishes different degrees of resistance, what allows establishing a seismic rating of the building.
