13. Avaliação do comportamento mecânico ao cisalhamento de conectores de barras de aço com ganchos em vigas mistas de madeira laminada colada e concreto
The main objective of this work was to propose a reference specimen for the push-out test of rod-type fasteners in timber-concrete connections. The following experimental tests have been performed in order to achieve the goals of this research: pull-out tests of bonded-in steel rods in wood specimens, pull-out tests of bonded-in steel rods in concrete specim

14. Almofada de apoio de compósito de cimento para ligações em concreto pré-moldado / Bearing pad of cement composite for connections in precast concrete
This research presents a study of a mortar modified to use as bearing pad between precast concrete elements. The mortar used in this research is achieved by the introduction of styrene-butadiene latex (SB) and polypropylene fibers into a cement mortar and sand, modifying their mechanical properties, as increase of the potential deformation by decrease of the

15. Connections and slab reinforcement of concrete-steel composite beams. / Ligações e armaduras de lajes em vigas mistas de aço e de concreto.
The use of composite steel-concrete beams is increasing in Brazil and in the world, because this is to take advantage of the best properties of each material. Steel has an excellent response to compression and tension and concrete has to compression. Composite beams include basically the steel beam, concrete slab, connectors and reinforcement. Some phenomena

16. Análise teórica e experimental de ligações viga mista-pilar de extremidade com cantoneiras de assento e alma / Theoretical and experimental analysis of single-sided beam-to-column composite joints with bottom and web angle connections
Este trabalho apresenta um estudo numérico e experimental do comportamento estrutural das ligações viga mista-pilar com cantoneiras de assento e alma. No estudo teórico foi desenvolvido, com base nos EUROCODES 3 e 4, um procedimento para avaliação do comportamento das ligações mistas com cantoneiras de alma e assento e com chapa de topo. O trabalho d

17. Composite beam-column connection Theoretical and experimental analysis / Ligações mistas viga-pilar - análise teórica e experimental
A composite joint is a joint between a composite beam and a steel or composite column in which reinforced concrete slab is take into account. The moment-rotation relationship of composite joints depends on a significant number of parameters besides the type and configuration of the steel connection, as for example: the amount of steel reinforcement of the sl

18. Pilares mistos preenchidos : estudo da flexo-compressão e de ligações viga-pilar / Concrete filled steel columns : a study of combined bending and compression and beam-column connections
Este trabalho aborda o estudo de pilares preenchidos flexo-comprimidos e algumas ligações viga-pilar preenchido. Para ambos, são realizadas experimentações com modelos físicos e numéricos, sendo que para os pilares preenchidos um amplo estudo paramétrico foi desenvolvido. Ao todo, foram ensaiados 13 pilares preenchidos flexo-comprimidos, cujos valore

19. DESENVOLVIMENTO DE SISTEMAS ESTRUTURAIS SEMI-RÍGIDOS EM AÇO E MISTOS PARA EDIFICAÇÕES RESIDENCIAIS MULTI-FAMILIARES / SEMI-RIGID COMPOSITE SYSTEMS FOR RESIDENTIAL BUILDINGS
Nowadays, despite the substantial increase in structural design knowledge, the semi-rigid connections steel design is still facing resistance from the structural engineers. This fact can be in part explained by few design standards that allows and explains their use, suitable computer programs and the lack of detailed information of the economical advantages

20. SISTEMAS CONSTRUTIVOS SEMI-RÍGIDOS MISTOS PARA EDIFICAÇÕES / SEMI-RIGID CONNECTIONS FOR BUILDING SYSTEMS / SISTEMAS CONSTRUCTIVOS SEMI-RÍGIDOS MIXTOS PARA EDIFICACIONES
This work focused on the development of an efficient and economic composite building system. This was accomplished by the conception of two new composite major axis connection details for external and intermediate columns. The external column connection detail motivated the creation of a new connection element: the T-rib connector. The main purpose of this e

21. ANÁLISE DO COMPORTAMENTO DE UM MURO DE CONTENÇÃO UTILIZANDO PNEUS / BEHAVIOUR OF A GRAVITY RETAINING WALL USING SCRAP TIRES / ANÁLISIS DEL COMPORTAMIENTO DE UN MURO DE CONTENCIÓN UTILIZANDO NEUMÁTICOS
Construction of a retaining wall using scrap tires and soil is presented in this thesis. The technique was developed as part of a research program at PUC-Rio in collaboration with University of Ottawa and Geo-Rio. The present work consisted of building and analyzing an experimental retaining wall which was constructed in Jacarepaguá, Rio de Janeiro and made
