1. Settlement of bored piles with expander body system in lateritic soils
Abstract The Expander Body pile (EB) is a combination of a cast-in-situ pile method with an inflated, pump-grouted tip. The EB system's pioneering conjunction with the conventional drilling pile technique has improved work load, foundation security, cost reductions and abrupt displacements in lateritic, porous, unsaturated soils. The aim of this article is t

2. Study of the interaction of concrete walls with the foundation structure
Abstract This article presents a study of the factors that influence the mechanism of soil-structure interaction with a pilot building having concrete walls and their impact on their performance. To illustrate the studies carried out, a numerical modeling of a four-floor concrete wall pilot building was performed, subjected to vertical actions, supported by

4. Collusion: How Central Bankers Rigged the World
Abstract This article presents a study on the performance of semi-empirical methods based on the Standard Penetration Test (SPT) for the prediction of bearing capacity already disseminated in the practice of Brazilian Foundation Engineering (Aoki and Velloso, 1975; Décourt and Quaresma, 1978, 1996; Teixeira,1996), together with the recent method proposed by

6. Interações ambientais e resistência física de um depósito de resíduos finos da indústria de rochas ornamentais
RESUMO Embora vários trabalhos proponham aplicações para os resíduos finos gerados no beneficiamento de rochas ornamentais, ainda não há evidências das vantagens financeiras para tal aproveitamento. Assim, a descrição dos depósitos existentes, muitos deles construídos sem triagem ou qualquer medida de proteção ambiental, torna-se imprescindível

7. Assessment of an Academic Skills Development Program for Youths in Juvenile Correctional Facilities
Resumo O déficit escolar é considerado um fator de risco para o desenvolvimento do comportamento antissocial. Esse estudo avaliou a eficácia de um programa para o desenvolvimento de habilidades acadêmicas para adolescentes em conflito com a lei. A amostra foi composta por 18 adolescentes, nove receberam a intervenção (grupo experimental) e nove partici

8. THE USE OF SIMULATION TO MODEL THE DISPATCH OF INBOUND CONTAINERS IN PORT TERMINALS
ABSTRACT This paper describes a study of the dispatch planning/scheduling process for inbound containers handled with a reach stacker. Client container pickup is scheduled at least one day in advance for one of six two-hour time windows (six five-container-high stacks per time window) on a given day. A buffer area is available for the containers to be moved

9. Estudio de propiedades mecánicas locales de uniones soldadas por fricción agitación (FSW) en AA6061-T6 mediante Small Punch Test (SPT)
ABSTRACT Friction Stir Welding (FSW) is a solid state process that has reach a strong technological impact in welding of aluminum alloys. Among its advantages, it may include the ability of joining materials that are difficult to weld by fusion. In welding of heat treatable aluminum alloys, some degradation in metallurgical properties is observed, so welds s

10. Estimación de propiedades mecánicas de materiales metálicos por el método inverso en SPT
ABSTRACT Mechanical characterization of metallic materials by Small Punch Test (SPT) allows to evaluate uniaxial tensile properties [1]. In this work, by means of an inverse procedure and numerical simulation of SPT tests we estimate uniaxial tensile properties of AISI 304L stainless steel. We detail the applied procedure to estimate the yield stress where t

11. Estimación de propiedades mecánicas de chapa de acero inoxidable 304L mediante ensayos SPT
ABSTRACT The mechanical characterization of materials by small specimen testing has growing interest in Structural Engineering. Small Punch Test (SPT) is applied to estimate mechanical properties of samples that can be extracted from components or structures without affecting service operation. In this paper the development of the test device is reported, co

12. Mechanical characterization of PM aluminum composites by small punch test
ABSTRACT In this work Small Punch Test (SPT) was applied to study the mechanical behavior of ultrafine-grained Al-Al2O3metal matrix composites (MMCs) fabricated in situ via powder metallurgy route (HITEMAL®). Such MMCs show attractive mechanical properties, enhanced creep performance and increased thermal stability at elevated temperatures, not normally ass
