“…Yapıyı meydana getiren her bir eleman için oluşacak hasar düzeylerinin kabul edilen sınır değerlerini sağlanıp, sağlanmadığının kontrolü mümkündür. Farklı büyüklükteki depremler için hedeflenen performans düzeylerinin öngörülen hasar sınır değerleri ile uyumlu olması gerekmektedir [30][31][32][33][34].

Öz Malzeme modelleri yapıların sismik analizlerinde önemli rol oynamaktadır. Literatürde, betonarme yapılarda kullanılan malzemelerin gerilme-şekil değiştirme ilişkisini tanımlamak için çeşitli malzeme modelleri bulunmaktadır. Beton ve çelik gibi iki farklı yapı malzemesinin bir arada kullanılması ile elde edilen betonarme yapılarda malzeme modelleri ayrı bir öneme sahiptir. Hem beton hem de çelik için kullanılan farklı malzeme modellerinin karşılıklı etkileşimi çalışmanın konusunu oluşturmaktadır. Çalışmanın amacı betonarme yapılarda kullanılan farklı malzeme modellerinin birbirleri ile uyumlu olup olmadığını kontrol etmektir. Bu çalışmada dörder farklı beton ve çelik malzeme modeli dikkate alınarak seçilen iki katlı betonarme bir yapı için hesaplamalar yapılmıştır. Her bir malzeme modeli için X ve Y doğrultularında taban kesme kuvveti-deplasman eğrileri elde edilmiştir. Çalışmada dikkate alınan malzeme modelleri hakkında bilgiler verilmiştir. Farklı malzeme modelleri arasında bir uyum olduğu gözlemlenmiştir. Bu malzeme modellerinin birlikte kullanılabilirliğini ortaya koymuştur.

The development of Textile Reinforced Mortar (TRM) has offered new potential for a number of applications in the field of structural strengthening. Its advantages over other strengthening techniques-such as compatibility with substrates, lower costs, better performance at high temperatures and high ductility-make the TRM vital for unreinforced masonry structures which are most vulnerable to seismic loadings. This paper presents a non-linear numerical simulation with a 2D finite element analysis (FEA) of TRM reinforced masonry walls under lateral in-plane loading. Simulations include the modelling of walls with and without openings; walls were modelled through a non-linear shelllayered element; brick masonry wall was modelled as a continuous material using two overlapping layers with different mechanical characteristics. The TRM was defined as a single shell of material for the mortar matrix and the mesh glass fibre applied through two layers that make up the reinforced plaster applied to the two faces of the wall. The increment of the maximum horizontal load and the high increment of ductility of the TRM retrofitted have been observed. Results provide a prediction of the plane's structural behaviour in order to propose a reinforcement method for masonry structures using a TRM.

“…In recent years, the mechanical characteristics of the masonry walls, which make up a historical building, have been a topic of discussion in various studies; in fact, due to the historical value of such structures, the use of traditional tests for the evaluation of the mechanical properties is not allowed. As a consequence, the researchers' attention was devoted to the use of dynamic tests and the results are utilized to obtain the global mechanical characteristics of the structure [1][2][3][4][5].…”

In the present paper the risk assessment of the medieval Norman tower of Craco (Matera, Italy) is discussed. Craco is a totally abandoned little town because of the activation of landslide motions of its soil depth. The medieval tower is one of the few buildings still standing as it is built on a fixed stiff foundation ground. Nevertheless, the tower is, indirectly, subjected to the movements of the close landslide. The tower is located in the highest and more stable part of the hill where the old town was built in the XII century for protection from enemy attacks. It is 20 m tall and has a (11 x 11) m 2 square plan. The basement has a truncated pyramid shape; originally it had two masonry vaults, one barrel on the first floor, which no longer exists, and a still visible cruise at the second order, connected by a now destroyed internal staircase. In 1949 a reinforced concrete cistern was placed inside the tower. Craco is classified as a town with a medium level seismic hazard. The main aim of the present study is to evaluate the seismic risk by means of a Finite Element model, calibrated through dynamic tests performed on the tower and considering the historical value of the structure and the context in which it stands. In fact, the structure is characterized by several peculiarities: the presence of a reinforced concrete cistern, the interaction with the surrounding buildings, the closeness to the landslide, the topographical exposition, etc. Moreover, the structure has a great impact on the society due to its touristic interest, as it is an emblem of the, so-called, "ghost town" of the Appennino mountains. A new approach is proposed to evaluate the effects of all the previously cited features on the evaluation of the seismic risk of the tower, introducing also economical and sociological parameters.
