Indirect assessment of the contribution of NSM CFRP laminates for the shear str...

Near Surface Mounted (NSM) strengthening technique has received increasing attention within the scientific and technical communities due to the positive indicators that this technique can provide in terms of strengthening performance. The NSM is especially effective for the shear strengthening of RC beams due to the ease of its application and the possibility of installing the Fibre Reinforced Polymer (FRP) ele...

Experimental characterization of a new reinforced brick masonry shell structura...

The main aim of the current paper is to describe the experimental research carried out at the University of Minho, Portugal, regarding the development of an innovative reinforced brick masonry shell structural system. The concept of the system is based on the work of the engineer Eladio Dieste, and focuses on the prefabrication industry. The structural system is composed of a layer of clay bricks, reinforced co...

Composite materials for the structural strengthening of reinforced masonry shells

Since the 1950s, the Uruguayan engineer Eladio Dieste designed curved lightweight masonry shells of impressive span width, complex shape and high attractiveness. This structural system is composed of a top mortar cover, a layer of clay bricks, mortar joints, and steel reinforcement. For the permanent loads, this structural system has been working satisfactory, in spite of rebar corrosion being detected in some ...

Flexural behavior of reinforced masonry panels

A new industrialized solution for construction of reinforced brick masonry shell roofs was recently developed. Here, the influence of both the brick and reinforcement arrangements on the flexural behavior of this structural system is analyzed by carrying out four-point bending tests with reinforced masonry panels. The panel positive flexural resistance (concrete cover layer in compression) was about two times i...

Estudo experimental sobre a pré-fabricação de cascas de alvenaria cerâmica armada

Tese de doutoramento em Engenharia Civil. ; Este trabalho insere-se num projecto financiado com a indústria, cujo objectivo é desenvolver os aspectos tecnológicos que permitam promover a construção de cascas em alvenaria cerâmica armada.

Testing, analysis and building technology for industrialized reinforced masonry...

This paper addresses briefly the research carried out at University of Minho, regarding an industrialized solution for reinforced masonry shells. The aspects of material characterization are presented, together with a contribution for a full prefabrication process. Aspects related to numerical analysis and structural design can be found in [1-3].

Cascas em alvenaria cerâmica armada : um exemplo de construção pré-fabricada

Comportamento à flexão de painéis representativos de um novo sistema construtiv...

Um sistema estrutural em casca de alvenaria cerâmica, com juntas e capeamento em betão armado foi desenvolvido para coberturas de pequeno e médio vão. Para avaliar a influência da ortotropia introduzida pela disposição dos tijolos e das armaduras no comportamento à flexão deste tipo de solução, bem como a resistência deste sistema aos momentos positivos e negativos, foram efectuados ensaios de flexão em quatro ...
