Masonry columns confined by composite materials: Experimental investigation
The present paper deals with the mechanical behaviour of masonry columns confined by using fibre-reinforced polymer (FRP) composites. In particular, it presents the key results of a wide experimental program jointly carried out at the Laboratories of the Universities of Salerno and Salento (Italy). Several kinds of masonry, made out of either natural or artificial bricks having different dimensions, have been tested in this experimental programme. A total number of 54 column specimens have been built and tested in pure compression. Moreover, several composite systems (mainly based on glass fibres) have been utilised as confining device by applying a variable number of layers that allow to develop different levels of lateral pressure. The present paper reports the complete information about the geometric and mechanical parameteis related to the tested specimens as well as the key aspects of the structural behaviour observed during the compression tests. In particular, the maximum load levels and the corresponding axial stresses and (average) strains are clearly reported. Finally, the main differences in terms of structural response due to the behaviour of the various materials utilised for both masonry and external wrapping are highlighted. Moreover, the same experimental results, along with further experimental data already available in the scientific literature, will be quantitatively analysed in a companion paper with the aim of calibrating a design formula for determining the axial strength of masonry columns confined by FRP.
