“…Proof load tests are necessary also for testing of replicas of historic timber machines, such as medieval cranes, before they are introduced into service on construction sites [7]. In situ tests provide the engineers with data necessary for the redesign or safety assessment of existing buildings, which is mostly used for masonry, timber, or concrete structures [8][9][10]. They were applied also for study of historic staircase structures [11,12] or free-standing gables [13].…”

The paper presents the results of static and dynamic experimental tests conducted on historical heritage structures and sculptures. In recent years, there was an increasing need to address the behaviour of these types of structures due to several reasons. Diagnosing the actual condition of a historical structure involves not only identifying the cause of a detected defect, but also determining its impact and assessing whether the structure can continue to perform safely. This article utilises unconventional loading methods to generate measurable mechanical responses. In one case, a lifting procedure is employed to study strains in a composite structure, while in another example, the mass and movement of people are used as a form of loading. Proof load tests conducted on a monumental sculpture allowed for the determination of load distribution among its heterogeneous structural components, namely a bronze shell and an iron reinforcing frame. Furthermore, the static and dynamic loading of a ceiling supported by a masonry vault demonstrated its ability to withstand anticipated loads resulting from unconventional use as a temporary exhibition space.
