Desenvolvimento de soluções de reabilitação: Grampeamento pós-construção de paredes de alvenaria de tijolo - Campanha experimental

Desta forma, desenvolveu-se um trabalho cujo principal objetivo passa pelo estudo de duas técnicas distintas de grampeamento pós-construção, mais concretamente o sistema Dryfix e CemenTie da marca HELIFIX ® , avaliando a resistência ao arranque de ambas as técnicas. Para tal, realizaram-se ensaios em laboratório de dois conjuntos de provetes de tijolos pertencentes a dois enquadramentos normativos distintos separados pela entrada em vigor da norma europeia NP EN 771-1 [1], a qual especifica as características físicas, mecânicas e as tolerâncias admissíveis deste produto. Os ensaios que se efetuaram para as duas técnicas foram realizados em provetes-tijolo isolados e em provetes-parede construídos com dimensão de 1,20 x 1,20 m 2 com o objetivo de representar a situação real de aplicação deste tipo de sistema de reabilitação.

This prefabricated hybrid composite plate (HCP) is made of a Strain Hardening Cementitious Composite (SHCC) reinforced with CFRP materials. Besides the higher durability of this system when compared to EB-FRP, thanks to the high ductility of the SHCC, anchors can be used in combination with adhesive to attach the HCP to the concrete substrate. The first section of this paper reports the methodologies to apply HCP for the repair of two severely damaged interior RC beam-column systems. To evaluate the performance of this rehabilitation technique, the repaired specimens were subjected to the same loading pattern as it was imposed to their virgin states. Since both repaired specimens showed a higher lateral load and energy dissipation capacities than the corresponding values in their undamaged state, the effectiveness of the HCP for the repair of damaged interior beam-column joints is proved.

Development of retrofitting solutions: remedial wall ties for masonry enclosure brick walls

Initially an experimental campaign was undertaken to carry out tests on 120 isolated specimens using some post and some pre NP EN 771-1 [1] clay bricks. A second campaign was carried out on wallettes built with dimensions of 1.20 by 1.20 m in order to represent a more realistic situation and evaluate slippage effects of the retrofitting solutions. Thus, this experimental work aimed to: i) assess the retrofitting technique in the laboratory environment; ii) to evaluate the efficiency of the retrofitting solution on specimens represented by post and pre NP EN 771-1 [1] clay bricks; iii) evaluate the influence of different features of the retrofitting technique (sleeve introduction and grout injection) over the pull-out test results; and iv) describe and catalogue the types of failure and behaviour of both techniques. All results for both retrofitting techniques are thoroughly presented and discussed.

Structural Behaviour and Retrofitting of Adobe Masonry Buildings

Different types of adobe dwellings are made to assure protection and wellbeing of the population according to the diverse zones needs. Therefore, it is importantstudy the structural behaviour of the adobe masonry constructions, analysing their seismic vulnerability, which may help in preventing social, cultural and economic losses. In the present chapter, an explanation of the seismic behaviour of adobe buildings, a summary of recent research outputs from experimental tests conducted on adobe masonry components and from numerical modelling of fullscale representative adobe constructions are reported. In addition, different rehabilitation and strengthening solutions are presented and results from the testing of retrofitted adobe constructions and components are discussed.
