One of the greatest strengths of ASDEA is the mutual collaboration between the project and facilities rehabilitation department and the research department. Our projects benefit thanks to the research carried out by members of ASDEA, as research topics often stem from actual needs identified in the design and rehabilitation of structures.
The members of ASDEA have research experience in institutions and national and international laboratories, which gives us a solid foundation of experience in various fields, including:
Since its opening, ASDEA has collaborated with other research institutions to carry out research in seismic engineering, in particular in the selection of seismic recordings aimed at analyzing the nonlinear dynamics of structures, the direction of motion and the dynamic behavior of structures in function of their damage
The members of ASDEA have carried out numerous studies relating to the behavior of masonry structures. The most relevant research is that on numerical modeling using equivalent frame, macro-modeling, micro-modeling and analysis of multi-scale homogenization.
The research carried out by ASDEA on composite materials is constantly developing and evolving in relation to the ongoing needs identified in the field of rehabilitation of existing structures. One of the first studies done on composite materials is similar to the performance analysis of elements in reinforced concrete fiber-composite materials, stochastic analysis of fiber-composite laminates and the analysis of the structural behavior of glass fiber tubes filled with concrete.
Research carried out by members of ASDEA on reinforced concrete is applied to various fields including: analysis of constitutive materials and their application to ad-hoc software, a comparison of experimental tests with numerical models, the study of micro-models aimed at understanding the interaction between concrete and steel, and the study of elements characterized by small imperfections and/or discontinuity with the theories of production mechanics.
DEVELOPMENT OF FINITE ELEMENTS, NON-LINEAR DYNAMIC AND STATIC ANALYSIS
The analysis of complex structures often leads to the need to analyze different types of finite elements. Some members of ASDEA do continued research on the formulation of finite elements and their applicability to concrete structures and masonry.
Non-linear static and dynamic analyses are applied in most of the research carried out by the members of ASDEA. Non-linear dynamic analyses are critical in determining the seismic and damage index to structural elements in reinforced concrete and masonry, as well as in all studies that relate to the analysis of damage to strategic and important and/or restricted structures and the determination of corresponding fragility curves.
Non-linear static analyses allow us to study the evolution of the structural damage up to the complete loss of its load-bearing capacity. By studying progressively applied loads, the type of damage to the structure is highlighted, as well as the evolution of the dissipative mechanisms until the point of collapse
Soil-structure interaction plays an important role in the field of earthquake engineering, although it is often overlooked at the design level. In collaboration with other companies, the members of ASDEA have developed extensive research both on the propagation of seismic waves in the ground and how they interact with the structure, as well as seismic amplification due to the topography and stratigraphy of the soil.
