【正文】 in order to be used in restoration of ancient masonries. C. Modena,M. R. Valluzzi,R. Tongini Folli, :A presentation is given of the fundamental design choices and of the selection of the most appropriate materials and techniques for which have been made for strengthening the Monza Cathedral BellTower,based on investigation and structural assessment carried out prior to and during the design process. The results of the experimental and numerical investigation are previously given in order to explain the reasons for the design choice. ,:one of the concerns with the conventional metal anchors that are used to tie the brick veneer to the backup portion of enclosure walls ( block) is the potential for corrosion. Corrosion reduces the loadcarrying capacity of such ties and this could lead to brittle failure especially in the event of an earthquake. In this paper ,the force in lateral ties in a typical brick veneer wall system are evaluated when the building is subjected to some earthquake records. Distribution of tie forces resulting from the dynamic analysis of a finite element model of the brick veneermasonry block wall system are determined and pared to the conventional assumption. The performance of a corrosion resistant stainless steel helical tie is pared with that of conventional ties. The potential advantages of this relatively new type of masonry tie are discussed with respect to its use in seismic regions. ,: an experimental study, performed on brick masonry 共 5 頁 第 5 頁 panels strengthened by Fiber Reinforced Polymer (FRP) laminates, was aimed to investigate the efficiency of an
