13. Tensile Behaviour and Durability Issues of Engineered Cementitious Composites with Rice Husk Ash
ABSTRACT The Engineered Cementitious Composites (ECC) is a special type of High Performance Fibre Reinforced Cementitious Composite (HPFRCC) characterized by a high tensile ductility with a 2% maximum volume of micro fibres. ECC has a tensile strain-hardening performance that leads to multiple cracking behaviour, thus providing the high ductility to the conc

14. BASIC UNIT COST SIMULATION FROM FREE-STALL DESIGN TO DAIRY CATTLE CONFINEMENT USING DIFFERENT CONSTRUCTION TECHNIQUES
ABSTRACT The ascendancy of milk production in Brazil is due to mainly to the adoption of confinement systems, however, construction quality of these systems impact on milk production. This study aimed to simulate the Basic Unit Cost (BUC m-2), referring to a free-stall design with capacity for 80 animals and different construction techniques, with a database

15. Effect of an Opening on Reinforced Concrete Hollow Beam Web Under Torsional, Flexural, and Cyclic Loadings
Abstract Hollow sections have been increasingly applied in the construction of buildings, bridges, offshore structures, and towers for passing electrical and mechanical pipes or other utilities. Torsion caused by external force is a weakness of hollow sections that is rarely investigated. In particular, the behavior of hollow sections with high-strength conc

16. Stochastic Analysis of Flexural Strength of RC Beams Subjected to Chloride Induced Corrosion
Importance of consideration of chloride induced corrosion in service life design of reinforced concrete (RC) structures situated in marine environment is well known. This paper attempts to provide, within the framework of Monte Carlo Simulation, methodologies for durability based service life design of RC members. A methodology using fragility curves is prop

17. Waste steel wires modified structural lightweight concrete
Nowadays, the use of different waste fibers in concrete has started to increase rapidly due to some reasons such as economic savings and positive effects on the environment. In this study, waste steel wires taken from reinforcement and formwork which were previously utilized in construction projects, were employed in structural lightweight concrete (SLWC). T

18. Study of structural capacity and serviceability affecting the obstruction of residential door
The last Chilean earthquake, occurred on February 27, 2010, allowed establishing important patterns of structural failures in reinforced concrete residential buildings; however, limited progress has been made in the study of basic standards of serviceability, such as obstruction of doors. Thus, this study focused on measuring the influence of design specific

19. INTERAÇÃO SOLO-ESTRUTURA DE EDIFÍCIOS COM FUNDAÇÕES SUPERFICIAIS / SOIL-STRUCTURE INTERACTION OF BUILDINGS ON SHALLOW FOUNDATIONS
This work deals with the consideration of Soil-Structure Interaction (SSI) in structural design of reinforced concrete buildings on shallow foundations of the isolated footing type. It carried out a comprehensive review on the major works done in the area and the methods for obtaining parameters and variables involved in the analysis. Numerical examples were

20. Modernidade concreta: as grandes construtoras e o concreto armado no Brasil, 1920 a 1940 / Concrete modernity: the largest construction companies and the reinforced concrete in Brazil, 1920 a 1940
Investiga-se através da atuação de grandes firmas construtoras no Brasil o desenvolvimento de novos sistemas construtivos, em particular do concreto armado, como um dos fatores protagonistas da modernização da arquitetura entre 1922 e 1937. Intenta-se examinar os diversos programas construtivos, através da premissa da técnica, e suas inferências na r

23. EI Scale: an environmental impact assessment scale related to the construction materials used in the reinforced concrete
This study aimed to create EI Scal, an environmental impact assessment scal, related to construction materials used in the reinforced concrete structure production. The main reason for that was based on the need to classify the environmental impact levels through indicators to assess the damage level process. The scale allowed converting information to estim

24. Analysis of creep and shrinkage and its utilization in health monitoring of reinforced concrete column. / Análise da deformabilidade por fluência e retração e sua utilização na monitoração de pilares de concreto.
This thesis presents the study of the time dependent deformation of concrete structures due to creep and shrinkage. Creep, shrinkage, compressive strength, splitting tensile strength and modulus of elasticity tests were performed in mixtures commonly used in construction. Experimental parameters were obtained from these mechanical characterizations and creep
