Assessment of damage of masonry walls as a function of displacements and repair costs

V diplomski nalogi smo na kratko predstavili bazo cikličnih testov na opečnih stenah. Cilj analize je bil, da s temi eksperimenti ugotovimo odnos med poškodbami ter pomiki opečnih zidov. V nadaljevanju naloge smo predstavili še nekaj tipičnih porušitev opečnih zidov in določili mejna stanja poškodovanosti. V nalogi je opisanih nekaj postopkov sanacije, kot so injektiranje, prezidava, prefugiranje, armiranocementna obloga, trakovi iz polimernih laminatov ter utrjevanje z vertikalnimi in horizontalnimi armiranobetonskimi vezmi. Za vse te postopke smo določili stroške, ki bi nastali tekom sanacije. Iz baze cikličnih testov smo izbrali šest preizkušancev, ki smo jih podrobneje analizirali ter določili ustrezno sanacijo in stroške. Za vsa mejna stanja poškodovanosti smo ocenili stroške sanacije in primerjali strošek sanacije (utrditve) s stroškom novogradnje. Na koncu smo primerjali še načine sanacije pri zidovih iz različnih materialov ter njihove stroške. Rezultati so pokazali, da so postopki in stroški sanacije odvisni od poškodb in materiala iz katerega je element sestavljen. Večina popravil poškodovanih zidov iz votlih opek je na enoto površine dražja od prezidave poškodovanega zidu ali stroška novogradnje, zato se pri takih zidovih redkokdaj odločamo za sanacijo.An overview of a database of cyclic tests of masonry walls is firstly presented in this thesis. The objective of the analysis of the database was to estimate the relationship between the damage and displacements of the masonry walls. A discussion on the typical failure mechanisms of masonry walls and definition of damage states is then presented in the first part of the thesis which addresses also the issue of rehabilitaiton and strengthening of masonry walls by different techniques. The aim of the thesis was to estimate costs of rehabilitiation and strengthening of masonry walls. For this reason six From the base of cyclic tests were selected from the database and analyzed in more details. The cost of reparing the damage in masonry walls was estimated and compared to the costs of construction of new wall. The results have shown that the procedures and reparing costs depend on the damage and the type of masonry. The cost of repairing of damaged walls per unit area is greater than the cost of replacing the wall or the cost of new construction.Therefore it not likely that hollow brick masonry will be reapried in the case of extensive damage
