Verificação no estadio I e II e na ruptura de seções em concreto protendido
… program has been developed for analysis of the working stresses, the ultimate limit state and the ultimate fadigue state of a post-tensioned concrete section subjected to a bending moment and normal force. The program allows the analysis of sections for any age of the structure, as well as …

Determinação da fluência do concreto e do coeficiente de Poisson diferido em um estado de tensões de compressão bi-axial
Present and analyse the first results of direct strain measurement in the concrete of the test slab (prestressed slab in two directions) of the Laboratório de Estruturas do Centro de Tecnologia da Universidade Federal do Rio de Janeiro. The purpose of the work is to observe the creep of the …

Model-based design of a ultra high performance concrete prototype highway bridge girder
In light of the current situation of highway bridge girders today, the Federal Highway Administration (FHWA) is constantly seeking to develop new bridges that can meet and adapt to current and future traffic, minimize environmental impact, require low-maintenance and are economical and easy to …

Experimental and analytical study of the shear transfer in composite shallow cellular floor beams
This research investigated the longitudinal shear transfer mechanism in composite shallow cellular floor beams. The shear transfer mechanism is different with the headed shear studs used in composite construction. The shear resisting properties and behaviour of the shear transfer mechanism has not …

Sustainable 3D Concrete Printing for Eco-conscious Construction: Recycled Aggregates and Low-carbon Binders
The construction industry faces increasing pressure from rapid urbanisation, rising infrastructure demand, and global climate imperatives, yet it remains a major contributor to environmental degradation. Concrete, and in particular Portland cement, contributes significantly to this challenge, …

Thermally-induced ratcheting behaviour of laterally-loaded reinforced concrete energy piles in sand
… and reducing carbon emissions from buildings or other infrastructure. It is subjected to vertical loading from the self-weight of the superstructure above, possibly horizontal loading due to pile eccentricity and cyclic thermal loading due to daily and seasonal temperature change. …

A Regional Study on Champlain Sea Clay: Empirical Prediction of Consolidation Parameters and Statistical Characterization of Undrained Shear Strength Based on Historical Geotechnical Data
This thesis explores the geotechnical challenges associated with the performance of geo-infrastructures on Champlain Sea Clay (CSC) deposits, with a particular focus on the Ottawa Valley region of Eastern Ontario. CSCs are highly compressible sensitive marine clays, which pose serious risks both …

Strength and Ductility of Concrete Cylinders Confined with Fiber Metal Laminate Composites
… are widely regarded as cost effective as the cost associated with retrofit installation and facility down-time are usually less than similar retrofit systems. Besides issues of bond and anchorage between the FRP and the substrate, the main disadvantage of FRP materials is that they behave …
