1. 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

2. Optimized dimensioning of steel-concrete composite beams
Resumo As seções mistas de aço e concreto estão cada vez mais sendo utilizadas na construção civil, tanto no cenário mundial quanto no Brasil. O trabalho conjunto do perfil de aço e da laje de concreto aumenta consideravelmente o desempenho do elemento estrutural misto devido ao aproveitamento das vantagens de cada material. Neste trabalho, é utiliz

3. Ensaio não destrutivo em revestimento cerâmico utilizando um protótipo para detecção de patologia
RESUMO No setor da construção civil há um crescente investimento na manutenção e reparo das construções, como por exemplo, as patologias encontradas nos pisos com revestimento cerâmico. Dentre as patologias mais comuns se pode destacar o assentamento inadequado das placas cerâmicas, que são caracterizadas pela perda de aderência de algumas placas

4. Influence of the methodology on the formation of zeolite membranes MCM-22 for the oil/water emulsion separation
Resumo Esse trabalho teve por objetivo produzir membranas zeolíticas MCM-22 utilizando dois métodos distintos de síntese, dip coating (DC) e transporte em fase vapor (VPT), para serem avaliadas no processo de separação emulsão óleo/água. As membranas foram preparadas a 150 °C por 10 dias, caracterizadas por difração de raios X e microscopia eletr�

5. Nonlinear numerical analysis of composite slabs with steel decking
Resumo O comportamento das lajes mistas é governado pelo cisalhamento longitudinal na interface entre o aço e o concreto, que é desenvolvido em lajes sob flexão simples. O método m-k e o método da interação parcial, utilizados no cálculo da resistência ao cisalhamento na interface aço-concreto de lajes mistas, são baseados em ensaios experimentai

6. Aço de alta dureza para aplicação balística: propriedades mecânicas
RESUMO Blindagens balísticas são projetadas a resistir determinadas ameaças, que dependem da aplicação. Estas ameaças podem ser geradas por projéteis de armas de fogo ou estilhaços provenientes de explosões com diferentes energias cinéticas. Os materiais normalmente utilizados para este propósito são metálicos, não metálicos e compósitos, sen

7. Numerical Investigation of Tension Reinforcement Lap Length of Eurocode 2 Using a Four-Point Beam Loading System
Abstract This report presents a computational research on Eurocode 2 (EC2) tension lap lengths (lo) design in a normally reinforced concrete beam, using ANSYS Workbench simulation software program by simulating a laboratory 4-point beam loading test system under static loading(discrete model approach). A typical 4-point laboratory setup loading system was mo

8. Numerical approach of the steel-concrete bond behavior using pull-out models
ABSTRACT This paper deals with the analysis of monotonic loading behavior in pull-out tests. The main objective is to obtain a reliable numerical model to represent the steel-concrete bond behavior using previously obtained experimental results. The tests were performed in RILEM pull-out specimen using 10 mm steel bar and concrete with compressive strength o

9. Vibration behavior of thin-walled steel members subjected to uniform bending
Abstract This article reports the results of an investigation on the effects of internal moments on the vibration behavior of thin-walled steel members. The analyses are based on the Generalized Beam Theory (GBT), a thin-walled bar theory accounting for cross-section in-plane deformations - its main distinctive feature is the representation of the member def

10. Removal of synthetic sex hormones by hydrothermal carbonization
ABSTRACT One of the most prominent fields of environmental chemistry is the study and the removal of micro-pollutants from aqueous matrices. Analytical techniques for their identification and quantification are becoming more sensitive and comprehensive and, as a result, an increasing number of drugs have been detected in environmental samples. However, the l

11. Experimental Investigation of Steel-Concrete Bond for Thin Reinforcing Bars
Abstract The steel-concrete bond is a fundamental property in reinforced concrete structures. Although there are several studies on the steel-concrete bond, few of them have evaluated the performance of reinforcing bars with diameters less than 10.0 mm, which includes 5.0, 6.3, and 8.0 mm diameters, which are normally used in reinforced-concrete elements.
