Teacher in Charge

Description

The Fernando Lobo Carneiro Structures and Materials Laboratory (LABEST) is a reference in experimental and numerical research in the field of structural and materials engineering. With a robust infrastructure and state-of-the-art equipment, LABEST is dedicated to the study of structures and building materials, ranging from the nanoscale to the macroscale of real structures.

The laboratory is able to carry out static and dynamic analysis on a wide range of structural components and complete structures, including buildings, bridges, shells, maritime and port works, offshore systems for oil exploration, hydroelectric power stations and other special structures. In addition, LABEST has expertise in testing various materials, such as concrete (including high and very high mechanical and environmental performance concrete, refractory concrete, micro-concrete for cementing oil wells and roller-compacted concrete), metallic materials, viscoelastic materials, resin composites, cement composites with metallic, plastic and organic fibers, as well as new construction and repair materials.

LABEST’s equipment enables special tests to be carried out, such as thermo-chemical-mechanical characterization of cementitious materials, slow deformation studies, durability, alkali-aggregate reaction, other expansive reactions, characterization of viscoelastic materials and structural identification. The laboratory is also equipped for tests with temperature variations, from ambient to 1,200°C, and has the capacity for structural monitoring in the field, complementing the tests carried out in its facilities.

Infrastructure

The laboratory specializes in the dynamic analysis of structures, covering activities such as structural monitoring and identification, vibration reduction and damage detection, with applications for both civil and offshore structures. It also has expertise in signal and image processing, meeting the needs of research lines related to dynamic analysis. This combination of skills enables the development of advanced solutions for studying the dynamic behavior of complex systems, contributing to the safety and efficiency of projects in various sectors.

Equipped with state-of-the-art technology, the laboratory has accelerometers and exciters for monitoring reduced models, a compression testing system for flexible risers with a capacity of 1200 kN, and systems dedicated to data acquisition and monitoring of rigid risers, including submerged versions for risers and torpedo piles. It also has equipment for tensile (1000 kN), torsion (150 kN.m) and crush (600 kN) tests on flexible risers, as well as systems for bending tests and simulating the loading of hydraulic collars. Other resources include a system for dynamic characterization of viscoelastic materials, a test platform for estimating human loads and an advanced image acquisition and processing system, consolidating its capacity to meet high-level research and development demands.

This line of research includes: (i) the scientific dosage of normal strength, high performance and very high performance concrete; (ii) behavior at high temperatures; (iii) the study of rheology; (iv) the study of durability and slow deformations; (v) computational modeling of flow and transport in porous media; (vi) the study of the micro and nano-structural properties of concrete; (vii) the study of sub-micro and nanometric particles and nano-fibers as inclusions in concrete; (viii) the study of fibrous concretes with multiple cracks in direct traction, reinforced fibrous concretes and textile composites; (ix) the development of concrete and composites with low environmental impact (see description in the environmental concentration area); (x) the study of special concretes for the oil industry (see description in the oil and gas concentration area); (xi) the use of advanced numerical modeling and computational intelligence techniques and (xii) micromechanical modeling.

This line of research includes: (i) experimentation and thermo-chemical-mechanical modeling of concrete behavior at early ages (ii) high-performance numerical modeling of hydroelectric plant structures (iii) experimentation and modeling of the alkali-aggregate reaction (AAR); (iv) the scientific dosage of roller-compacted concrete (RCC) (v) the development of new materials for powerhouses and spillways (vi) the use of computational intelligence techniques for dam safety.

This line of research is aimed at developing mathematical models and numerical and computational solutions for analyzing the stability, non-linear behavior and sensitivity characteristics to imperfections and initial conditions of structural systems subject to pseudo-static and/or dynamic actions.

Theoretical and numerical development of tools for the analysis and design of civil structures subjected to dynamic loads produced by people, machines, vehicles and environmental actions (wind, waves, earthquakes). Application, via theoretical and numerical models, of systems to control structural vibrations in order to meet the required safety, durability and use limits. This line of research has a strong interaction with Structural Identification, since the methodologies developed are evaluated through experimental tests.
