Application of selected modern technology systems to strengthen the damaged masonry dome of historical St. Anna’s Church in Wilanów (Poland)

AbstractThe aim of the paper is to present a study on the cracked brick masonry dome of the historical church of St. Anna in Wilanów (Poland), founded in 1772 and entered in the Polish register of monuments in 1965. The calculation of static-strength for strengthening the dome was carried out taking into account the characteristics of the vaulted construction works and a relevant existing structure with designed elements of the strengthening construction works based on using carbon tape SIKA CarboDur) and spiral steel rods in the HELIFIX system. The use of a three-dimensional structural model of the masonry dome allowed a detailed determination of the internal force distribution and the adoption of an appropriate repair and strengthening regime for this load-bearing structure. The correctness of the design solutions and calculation assumptions is reflected in the fact that, after a period of more than three years, no damage to the repaired elements of the masonry dome occurred
