Arhitektonska i strukturna analiza povijesnih građevina

Abstract

Architectural and structural analysis of historical structuresHistorical structures are integral to the cultural heritage of the world and ought to be safely preserved for posterity. An interdisciplinary approach is critical in the conservation and restoration of masonry structures. Taking this into consideration, this study discusses Gok Madrasah, a 750 year-old structure situated in Amasya, Turkey, in terms of art history and structural engineering. An analysis of decorative elements is made in the paper from an art-history aspect, and a detailed three-dimensional finite element analysis of the structure is conducted. Analiza konstrukcije povijesnih građevina iz arhitektonskog i građevinskog aspektaPovijesne građevine značajan su dio svjetske kulturne baštine i trebaju se na siguran način sačuvati za buduće naraštaje. Interdisciplinarni pristup izuzetno je važan za očuvanje i restauraciju zidanih građevina. Imajući to na umu, u radu se s aspekta povijesti umjetnosti i stabilnosti konstrukcije razmatra medresa Gok, građevina stara 750 godina, smještena u Amasyji u Turskoj. U radu je provedena analiza dekorativnih elemenata iz povijesno-umjetničkog aspekta te detaljna prostorna analiza konstrukcije metodom konačnih elemenata.

An Assessment of the Performance of the Amasya Bayezid II Mosque Under Static and Dynamic Loads

“…The lateral deformations and tensions at these locations necessitate the use of iron braces. It is safe to state that the architects of the Ottoman architecture were aware of this and took the necessary precautions (Çakır and Koçyiğit, 2016). The dynamic analyses indicated that the main domes, the narthex, and the minarets, all of which are involved in the movement of the building, could be damaged.…”

“…The main mass, narthex, minarets, and arches, were built using face stones, while the domes were built with bricks from Khorasan. The physical and mechanical properties identified in the laboratory tests performed on the materials that were used in another work in the same city were assigned to these parts (Çakır and Koçyiğit, 2016). The physical and mechanical properties of these materials are presented in Table 1.…”

Remediation of traditional stone columns by lead inlays

“…It is difficult to identify this problem by traditional calculations, using for instance approximate graphical methods, and by selecting usual relationships between structural elements [8] or the compression-tension analogy, simply because the displacements are very small. On the other hand, global structural models that are most often used in modern numerical calculations [9] cannot adequately cover complex behaviour of small details, especially in the post-critical region (where many specific data are required). Furthermore, common experimental tests, involving determination of axial force levels in columns of historic buildings, are normally not conducted in the vicinity of contacts, and may lead researchers to totally wrong conclusions, as stress concentrations are already distributed (Figure 2.d).…”
