Sažetak
Nowadays, when experts consider sustainability, they are mainly concerned with global factors that endanger our civilization and even our survival as well as survival of other species. Climate change is an example of such a menace. In the past, when threats were caused by local factors, such as local floods and earthquakes, the sustainability of structures can be defined as the quality of structures to resist adverse events without endangering human lives and thus to provide safety to individuals and societies. In this context, the buildings from the past that came to us as still existing structures testify to their sustainability. The ones that resisted severe earthquakes without serious damage are worth studying, because they can offer valuable insight into their seismic behavior and thus reveal the “secrets” of their resilience. The understanding of what makes certain historical structures earthquake-resistant is precious for modern engineers, in order to design sustainable, seismic resistant buildings. In fact, even nowadays, with our advanced knowledge in mechanics and our computational and experimental methods, it is hard to reliably model structural behavior of a real building submitted to earthquake vibrations. Thus, the study and analysis of earthquake-resistant structures from the past is a precious source of knowledge that should be applied for future sustainable building. As a contribution to this knowledge, traditional timber structures in continental Croatia have been analyzed. In the recent earthquakes in Zagreb and Banovina regions, traditional timber houses proved to be earthquake resistant: no damage of these traditional timber houses of the region was recorded, while newer masonry structures and even some reinforced concrete structures suffered considerable damage. The analysis of these structures showed that the proven seismic resistance of traditional timber houses in this region is due to the specific way of construction. The walls of traditional timber structures in these regions have been constructed of horizontal logs or planks connected with dovetail joints, which require high 3D precision and mastery of builders. This type of joints enables micro-displacements and thus dissipation of seismic energy. Of special interest is a detail used in the past for connecting lower part of traditional timber houses (their foundations) with their upper parts (walls). This detail enables relative displacements of the upper structure with respect to its lower part, providing a seismic isolation of the structure. The principle of seismic isolation has been only recently applied by modern engineers to assure seismic resistance of important new buildings. Even though the theory of mechanics was not known in the past, the principle of seismic isolation was applied by traditional master-builders to create resilient earthquake- resistant structures. This testifies that empiric knowledge of generations of master- builders is worth studying even today.
