The area of Structures is directed toward cutting-edge scientific research, training professionals (engineers and researchers) to very high standards and enabling them to solve major engineering problems, while generating scientific and technological knowledge and disseminating it in society. This area is divided into two major lines of research: Numerical Analysis of Structures, and Experimental Analysis and Mechanical Behavior of Structural Elements and Systems (AECMESE).

Research within the Numerical Analysis of Structures line of research encompasses the Center of Optimization and Reliability in Engineering (CORE), founded in 2012. The Center’s activities are focused on the theoretical development and application of numerical tools for the solution of complex engineering problems, including the quantification of uncertainties and structural reliability, optimization and computational mechanics (static, dynamic, linear and nonlinear analysis). Five researchers work at CORE, two of them being CNPq researchers of level 2 productivity, with over thirty-five articles published between 2013 and 2016, in the most highly regarded international journals of the area. CORE researchers have actively taken part in research and development (R&D) projects in the areas of electric power transmission towers, oil wells and reinforced concrete bridges. They have formed scientific partnerships with several Brazilian universities, including USP, UFPB, UFRGS, UFRJ, PUC-Rio, UTFPR and FURG. Currently, the main interactions with foreign institutions are with the Optimization and Reliability in Mechanical Structures Laboratory (LOFIMS), of the National Institute of Applied Sciences of Rouen – France, and the Center for Uncertainty Quantification in Computational Science & Engineering, of the King Abdullah University of Science and Technology (KAUST), Thuwal – Saudi Arabia. Besides the development of scientific research ties with these universities, processes of co-supervision have been initiated. Concerning the attraction of financial resources from industry to support cutting-edge scientific research at the university, CORE is currently working in partnership with the Department of Structural Engineering at EESC/USP, the Department of Mechanical Engineering at UTFPR and the Center of Research and Development (CENPES) of PETROBRAS S.A.

The Structural Analysis and Design Group (GAP), which operates within the Numerical Analysis of Structures line of research, has been working in the areas of Structure Design and Energy Generation and Transmission Structures, together with companies in the field of engineering and structure design software.

Working within the AECMESE line of research are the Nondestructive Testing Research Group (GPEND) and the Interdisciplinary Wood Studies Group (GIEM).

GIPEND focuses on the development of techniques for nondestructive testing (e.g. ultrasound, infrared), mainly applied to reinforced concrete and wooden structures. In relation to the international collaborations of the group, GPEND works on research projects with different universities and research institutes, such as the ZAG Institute in Ljubljana, Slovenia.

GIEM was created at the Civil Engineering Department in 1999 and currently three researchers form the group: two from UFSC and one from IFSC. They carry out research and disseminate technical information in the area of wood materials through consultancy and studies linked to the Civil Engineering and the Architecture and Urbanism Graduate Programs at UFSC. Their activities are concerned with the search for clean and low cost technological alternatives, which can improve the performance of the industrial sector dealing with wood materials. The themes addressed at GIEM include the physical and mechanical characterization of forest species and forest-based materials, experimental analysis and modeling of structures, mechanical behavior of wood on exposure to high temperatures and fire, the durability, reconstruction and reinforcement of wooden buildings, diagnosis and preservation of historical heritage buildings constructed in wood and design criteria for wooden structures. GIEM has continuously worked in the training of human resources through doctoral degrees, master’s degrees and students in scientific initiation programs, maintaining technical-scientific collaborations with national and international institutions. The national institutions include the Regional University of Blumenau (FURB), The University for the Development of Santa Catarina State (UDESC), the Federal University of Pará State (UFPA) – Tucuruí, Pará, and the State University of Western Paraná (UNIOESTE) – Cascável, Paraná. The international institutions include the Science and Technology College (FCTUC) of the University of Coimbra – Portugal, with which a transnational cooperation project FCT/CAPES was developed, the University of Magallanes – Chile, University of Minho – Portugal, National Higher-Education School of Industrial Technologies for Wood Materials of Épinal – France, and the University of Padova – Italy.

GIEM is currently developing a doctoral program funded by ELARCH – the Euro-Latin America partnership in natural Risk mitigation and protection of the Cultural Heritage. Interaction with companies manufacturing wood-based products, such as Battistella and Lavrasul SA, along with state-run institutions, such as SESI-SC, Urban Planning Institute of Florianópolis (IPUF), Culture Foundation of Santa Catarina State (FCC), National Heritage Institute of History and Art (IPHAN), and the Coordination of the Fortresses of Santa Catarina Island at UFSC, forms part of the activities of GIEM. In relation to the design of wooden structures, GIEM is taking part in the commissions for the proposal of the Brazilian norm ABTC/CB-31 (Wood Frame) and the revision of the norm ABTN 7190 (Design of Wooden Structures).
