“…Due to bad connection detail of the intersections, safety of the connections relied on tensile strength of the mortar used for connection. Unconnected walls were more prone to out-of-plane failures (Kaplan, et al, 2008). These types of deficiencies were not limited to external wall-partition wall intersection.…”

Van, a city in Eastern Anatolian Turkey, was hit by two earthquakes with magnitudes of Mw = 7.2 and Mw = 5.6 in October and November 2011. Both earthquakes caused extensive damage to many buildings. Unreinforced masonry buildings, especially in rural areas, suffered from those earthquakes extensively as in many other cases observed in Turkey during other previous earthquakes. This paper presents a site survey of damaged masonry buildings. Reasons for the wide spread damages are discussed in the paper

“…More than 80 000 people died and about 500 000 building collapsed or were heavily damaged (Cagatay, 2005). There are numerous studies in the literature about the earthquake hazards and corresponding post earthquake studies in Turkey (Catal, 1997;Arslan, 2006;Ulusay, 2004;Ulusay, 2005;Sancio, 2002;Bayraktar, 2004;Erdik, 2004;Binici, 2007;Guchan, 2007;Inel, 2008;Pamuk, 2005;Kaplan, 2007;Korkmaz, 2009). …”

Abstract. During the last earthquakes in Turkey, reinforced concrete structures in the cities and masonry structures in the rural part were exposed to damage and failure. Masonry houses such as earthen, brick and stone structures are composed of building blocks with weak inter-binding action which have low tension capacity. Bending and shear forces generate tensile stresses which cannot be well tolerated. In this paper, the performance of masonry structures during recent earthquakes in Turkey is discussed with illustrative photographs taken after earthquakes. The followings are the main weakness in the materials and unreinforced masonry constructions and other reasons for the extensive damage of masonry buildings. Very low tensile and shear strength particularly with poor mortar, brittle behaviour in tension as well as compression, stress concentration at corners of windows and doors, overall unsymmetry in plan and elevation of building, unsymmetry due to imbalance in the sizes and positions of walls and openings in the walls, defects in construction such as use of substandard materials, unfilled joints between bricks, not-plump walls, improper bonding between walls at right angles etc.

“…However the Great Marmara Earthquake was a turning point on the society, executives and engineers. Then, seismic performances of many public buildings have been inspected and a vast majority of them have not satisfied the desired seismic performance [1][2][3][4]. In order to strengthening that type of structure, many codes [5][6][7][8] and a bulky literature [9][10][11][12] are available.…”

Uncontrolled growing of construction industry in Turkey has caused a large number of buildings were constructed without the benefit of sufficient engineering supervision. These phenomena have contributed to the increase in the number of seismically weak buildings. After the Great Marmara Earthquake seismic performances of the existing structures have been inspected and some of them fortified. In this context, an existing building foundation, built on a problematic soil and located in Denizli where is in high seismic risk area, has been strengthened by cement injection. Grouting holes up to 7 m in depth from the basement level were used in 45 points. The injection has created a less permeable barrier, acts like an underground dam. This barrier has caused rising of the underground water table around the recharge area of the foundation. The raised underground water has increased hydraulic gradient and hydraulic pressure. Then, the basement floor has arched up to 12 cm and underground water has risen up to 30 cm high after one year of the injection practice. In this study, hydrogeological characteristics of the soil structural analysis have been evaluated and some solutions suggested remedying the problem. It should be kept in mind as injection practice is employed in aquifers.
