    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

    The fundamental design choices and of the selection of the most appropriate materials and techniques which have been made for strengthening the Monza cathedral bell-tower, based on investigation and structural assessment carried out prior to and during the design process are presented. The results of the experimental and numerical investigation will first be given in order to explain the reasons for the design choice
