The Example of using long-term monitoring and non-invasive measurements for Structural Health Monitoring. Cause study of St. Anna's Church in Warsaw

Abstract

Heritage objects are affected by many factors that affect degradation over time and damage to historical sites. For this reason, it is necessary to carry out continuous monitoring using non-invasive techniques for Structural Health Monitoring and plan the conservation works. This article aims to present the results of a project that involved long-term monitoring using surveying techniques such as precise tacheometric measurements, precise levelling, inclinometric measurements and crack measurements using crack gauges. This paper presents the results of multisensor monitoring of displacements and cracks in the building, which contributed to the conservation efforts and prevent works. A research object is St. Anne's Church in Warsaw. It is one of the few in Warsaw that wasn't destroyed during World War II.

“…Each case study presents different scenarios with different challenges related to 3D reconstruction, especially with respect to conventional MVS. These case studies comprise thus the following sites (Table 1): (1) the interior main hall of Warsaw University of Technology ("Hall") with a remarkable glass ceiling, walls and another architectural elements made of marble, sandstone and bricks (Markiewicz & Zawieska, 2015); (2) the dome of the Ladislas chapel in the church of St. Anne in Warsaw, Poland ("Chapel") consisting of detailed Rococo wet-painted frescoes (Górecka et al, 2022); and…”
