Abstract
Preliminary laboratory tests that have been already carried out on wallettes subjected to monotonic loading and loading by steps of constant load (pseudo creep test), have shown that the above use can fulfil the requirements. Test results and preliminary numerical investigations indicated the way how the intervention can be designed by appropriately choosing the material properties and the dimensions and positions of the strengthening bars. In field applications, subjected to continuos monitoring of the cracks width after the intervention, already demonstrated the feasibility of the techniques and his positive effects. Based on the previous consideration a systematic investigation has been started, in order to study more in detail the effect of a repair technique, specifically finalised to the dilation control, in the long term mechanical damage of the masonry. The above research and field application experiences are presented and commented.Pubblicazioni consigliate
