1. ROBÓTICA EDUCACIONAL, ENSINO DE QUÍMICA E APRENDIZAGEM COOPERATIVA: UMA PROPOSTA PARA O CURSO DE ENSINO SUPERIOR EM ENGENHARIA CIVIL
Students, generally, are afraid of studying chemistry because they understand that it is a very complex area of knowledge and that it doesn’t has use in daily lives and in intended profession, which is a problem we identified in a Civil Engineering course. With this, we proposed a project in this course, based on educational robotics and educational cooper

2. Revised formula for predicting the long-term deflection multiplier of normal and high strength concrete
Abstract High strength concrete (HSC) has found many applications in civil engineering structures such as in high-rise buildings, and bridges. The mechanical properties of HSC are sometimes different than of normal strength concrete (NSC). In particular, HSC possess lower creep strains compared to NSC. As a result, members constructed using HSC have been fou

3. Utilização de um sensor de umidade para o Arduino na determinação da curva característica de retenção de água por um sistema poroso
Resumo Neste artigo é apresentada a utilização de um sensor de umidade para o Arduino no levantamento da curva característica de retenção de água por um sistema poroso, tal como, por exemplo, o solo. Essa curva é muito importante nos estudos ligados à caracterização físico-hídrica do meio poroso. Sua determinação possibilita a investigação d

4. GRAPHICAL REPRESENTATION ANALYSIS OF COMPLEMENTARY CIVIL PROJECTS USING "CAD 2D", "BIM" AND "RA" AND IDENTIFICATION OF INTERFERENCES
Abstract Technical graphic representation presents problems concerning the reduction of dimensionality from 3D to 2D. AEC (architecture, engineering and construction) projects usually adopt the top view paradigm with two-dimensional orthogonal projection. Recently, three major changes in technical representation were the alteration of orthogonal projection i

5. USE OF GROUND PENETRATING RADAR TO STUDY SPATIAL VARIABILITY AND SOIL STRATIGRAPHY
ABSTRACT Ground Penetrating Radar (GPR) is a geophysical method that uses electromagnetic waves to study subsurface structure in different fields such as geology, agriculture and civil engineering. The wave penetration in the soil is strongly controlled by the electrical conductivity of soil components such as clay, organic matter, and water. In this study,

6. Efeito da adição de resíduos da construção e demolição (RCD) nas propriedades hidromecânicas de um solo areno-argiloso
RESUMO Diante de uma produção cada vez mais evidente dos resíduos sólidos resultantes das ações humanas, tais como os Resíduos da Construção e Demolição (RCD), destinar adequadamente estes materiais tem ganho importância no cenário atual, pois quando dispostos irregularmente atuam de forma degradante sobre o meio ambiente e contribuem com a prol

7. Ensino de projeto dos sistemas prediais hidráulicos e sanitários: abordagem baseada em problemas
Resumo O escopo e a complexidade do projeto dos sistemas prediais hidráulicos e sanitários vêm aumentando ao longo dos anos, sendo necessário que os alunos de graduação desenvolvam habilidade de análise. Além disso, a dificuldade de concentração por longos períodos, característica dos jovens na atualidade, fazem com que as aulas expositivas sejam

9. New mathematical modelling for grain size distribution adjustment in concrete
Abstract Concrete used in civil engineering is a composite obtained from the combination of coarse and fine aggregates, cement and water, and its cost and quality are normally associated to the proportion of its constituents (ceramic formulation), as well as the reduction of water consumption. The aggregates used in concrete may have diverse origins, and the

10. Effectiveness of track stiffness reduction in attenuation of metro induced vibrations received by historical buildings
Abstract Preservation of historical buildings is a main challenge in civil engineering field. One of the main concerns in this regard is metro induced vibration received by historical structures. There is a need to evaluate effectiveness of vibration mitigation measures in preservation of monumental buildings. The most widely used method of reducing metro vi

11. Damage evaluation and failure mechanism analysis of steel tube confined reinforced-concrete columns by acoustic emission technology
Abstract As a new kind of composite structures and its advantages, the using of steel tube confined reinforced concrete (STCRC) columns have received increasing attention in civil engineering. Acoustic emission (AE) technique is applied to monitor the damage process of STCRC columns during an uniaxial compression test. The aim of this study is to investigate

12. Nondestructive ultrasonic testing in rod structure with a novel numerical Laplace based wavelet finite element method
Abstract Rod structure has been widely used in aerospace engineering and civil engineering. Nondestructive testing is a very important method applied to detect unseen flaws in structures, ultrasonic wave nondestructive testing has been used in many areas. Finite Element Method is one of the most widely used numerical methods but would have a high cost when d
