SPT-T: test procedure and applications
(Geotechnical and Geophysical Site Characterization Vols 1 and 2, 2004-01-01) [Trabalho apresentado em evento]
Ranzini (1988) proposed the Standard Penetration Test with torque measurement (SPT-T) and some geotechnical engineers in Brazil have been using it since 1991. This paper presents the state of the art on SPT-T testing, ...
Geotechnical and structural behavior of the railroad track in large-scale apparatus
(Proceedings of the 17th International Conference on Soil Mechanics and Geotechnical Engineering: The Academia and Practice of Geotechnical Engineering, 2009-12-01) [Trabalho apresentado em evento]
This paper analyses the static and dynamic behavior of the railroad track model in laboratory. Measurements of stresses and strains on a large-scale railroad track apparatus were studied. The model includes: compacted soil, ...
Geoenvironmental site investigation using different techniques in a municipal solid waste disposal site in Brazil
(Environmental Geology, 2007-05-01) [Artigo]
Different geoenvironmental site investigation techniques to assess contamination from a municipal solid waste disposal site in Brazil are presented here. Superficial geophysical investigation (geoelectrical survey), ...
Fadiga em dormentes de concreto reforçados com fibras de aço
(Ciencia y Engenharia/ Science and Engineering Journal, 2001-07-01) [Artigo]
A prestressed concrete monoblock railroad tie was designed to attend the characteristics of a Brazilian railroad track with 1,600 mm gauge and 320 kN axle load. Concrete ties specimens were manufactured without and with ...
Aplicação integrada de métodos geofísicos em uma área de disposição de resíduos sólidos urbanos em Bauru-SP
(Revista Brasileira de Geofísica, 2006-09-01) [Artigo]
A geofísica tem mostrado eficácia em identificar áreas contaminadas pela disposição de resíduos sólidos urbanos, contribuindo para tornar mais efetivos os programas de sondagem voltados à coleta de amostras e instalação ...
About the Use of the HdHr Algorithm Group in Integrating the Movement Equation with Nonlinear Terms
(Mathematical Problems in Engineering, 2009-01-01) [Artigo]
This work summarizes the HdHr group of Hermitian integration algorithms for dynamic structural analysis applications. It proposes a procedure for their use when nonlinear terms are present in the equilibrium equation. The ...
Embedded crack elements with non-uniform discontinuity modes
(Measuring, Monitoring and Modeling Concrete Properties, 2006-01-01) [Trabalho apresentado em evento]
The consequences of the use of embedded crack finite elements with uniform discontinuity modes (opening and sliding) to simulate crack propagation in concrete are investigated. It is shown the circumstances in which the ...
Resistência à compressão do concreto autoadensável: Influência da atividade pozolânica do calcário e do basalto
(Ciencia y Engenharia/ Science and Engineering Journal, 2006-12-01) [Artigo]
This research studies the influence of the pozzolanic activity of the calcareous and basalt in the resistence behavior of the compressive strength of high performance self-compacting concrete (HPSCC). The selected aditives ...
A theoretical and experimental analysis of cold-formed steel shapes subjected to bending - Channel and simple lipped channel
(International Specialty Conference on Cold-Formed Steel Structures: Recent Research and Developments in Cold-Formed Steel Design and Construction, 2000-12-01) [Trabalho apresentado em evento]
Cold-formed steel shapes have been widely employed in steel construction, where they frequently offer a lower cost solution than do traditional laminated shapes. A classic application of cold-formed steel shapes is purlins ...
Avaliação comparativa de métodos laboratoriais de medição de resistividade elétrica do solo: Uma abordagem teórica
(Solos e Rochas, 2006-09-01) [Nota]
