The aim of this study was to evaluate the structural health of a 19th-century warehouse located in Trondheim using a drilling resistance device. The building, Kjøpmannsgata 27, is one of the many bryggene which are situated along the river Nidelva. These buildings were used in the past as warehouses and repositories. They represent the peak period of the town's commercial expansion during the 18th and 19th centuries and are considered an important part of the city's historical profile. The building has many structural issues, especially in the basement where the structure is in direct contact with the ground. A visual survey of the building was carried out prior to drilling resistance testing. The combination of these two methods was used to locate decayed wood and critical areas in need of repair. The foundation beams were found to be in the worst state of decay. Measurement of the drilling resistance proved to be a useful method for evaluating the condition of the building's structure, providing the basis to plan its rehabilitation.

Vaernes church is one of the oldest mediaeval stone churches with the original wooden roof in Norway. The roof is made of several crossed layers of wooden boards connected with a large number of wooden dowels and has stood for centuries, but there are visible deformations in the lower parts of the structure. In this work, finite element models of the roof are presented in an attempt to characterise the behaviour of the wooden connections in the diaphragm. Two main scenarios are discussed: a first scenario that takes into consideration only the frame with line loads, considering the wooden boards merely as loads and a second scenario where the wooden boards are considered collaborating planks that influence the behaviour of the structure. As result of the work, it is possible to state that the wooden planks provide a stiffening effect, distributing the load on the gable walls. .
