| Sumario: | The study focuses on the case of the Church Santa Maria de Barberà de la Conca, a three-nave baroque masonry Church, built during 18th century, located in Catalonia. Because of the significant damage that the Church is suffering, and the fact that the ground movement and the opening of cracks are continuing, it is necessary to quickly implement stabilization or strengthening solutions because the Church is threatened with collapse. The severely damaged Rose Chapel was demolished recently, and the Church and its surroundings are closed. The study also describes the current monitoring of progressively growing soil cracks. Existing structure calculation was done based on graphic static analysis, a simple, fast, convenient, and straightforward method to determine the Church's stability in the initial state versus the stability in the currently damaged stage. The second goal of the graphic static analysis was to determine the internal forces and base reactions as input for the strengthening solution calculation. By considering possible alternative solutions for the strengthening of the Church, it was established that it is necessary to strengthen the Church at the foundation level. A chosen solution with sufficient capacity to resist the large tensile forces that the movements of the soil may cause can be provided in the form of a prestressed concrete grillage rigidly connected to the existing masonry walls. The solution is designed as a reversible one, in the way that the transverse prestressing is without grouting. Additionally, the maintenance plan and monitoring of the prestressed structure is foreseen to monitor the level of force achieved with the strengthening solution. Finally, repair and strengthening operations designed for the rest of the structure (walls, pillars, arches, and vaults) are briefly described to stabilize the Church entirely and restore it, enabling its public use again. |
