Steel and Mixed Structures
This line of research aims to develop steel and mixed steel and reinforced concrete construction systems, which can offer reduced costs and construction time. The industrial segment that can benefit most from the results of this research is the construction of multi-story buildings and industrial warehouses and supply distribution centers. Structures of large spatial coverings and tensile structures, composite slabs, composite connections and steel structures for the oil and energy sector are also studied.
Theoretical and experimental research is also carried out on problems of loss of stability in statics and non-linear dynamics of structures. The theory of structural stability is linked to the foundations of structural mechanics and continuum mechanics. The demand for research in this area has occurred in the face of the development of the civil, naval, oceanic and aeronautical industries, with changes in structural concepts and demands for more precise verification of the behavior of structures. Complex mathematical and computational models are required to simulate such systems. Recently, the importance of this classic topic in structural engineering has been recognized in other areas of research, notably in the areas of nonlinear dynamics, vibration control and material instability. This line includes the study of the instability, penetration and cavitation of hyperelastic membranes and the instability of hyperelastic shells.
- Reinforced/prestressed concrete: shear in beams, punching in slabs and residual resistance of elements subjected to high temperatures;

- Geopolymeric concrete reinforced with natural fibers: development and evaluation of the behavior of structural elements in composites with a geopolymeric matrix;
- Textile concrete: performance and resistance of slender beams and columns in cementitious composite reinforced with carbon fiber fabric;
- Glass fiber reinforced polymer: instability of beams and columns of pultruded profiles made of glass fiber reinforced polymer.
Engineering Project Methodologies
This line of research aims to investigate new methodologies to improve the workflow of engineering projects. In particular, the use of the BIM methodology (construction information modeling) is explored in the integration between the various disciplines involved in the project as well as the different phases of the project. This methodology uses sophisticated computational tools that centralize design information along with the 3D digital model. Interoperability between computational tools is one of the main factors for the successful use of the BIM methodology in its entirety. In this line, research is carried out related to interoperability between software, electronic document management, and adaptation of the BIM methodology to the Brazilian reality.
