Reinforced concrete framed residential buildings are remarkably common in Turkey. Observations after recent earthquakes revealed that a great portion of the present building stock has inadequate seismic resistance. Moreover, collapses of several multi-story reinforced concrete buildings under their self-weight have also been observed despite any dynamic activity. The tragic example of the collapse of the "Zumrut" residential building under its self-weight in 2004 and the death of its 93 occupants have highlighted the need to re-examine the structural safety of existing buildings throughout the country. In this study, a multi-story reinforced concrete building located in the same city where the Zumrut disaster occurred, has been investigated. The damage occurred under its self-weight and their causes have been studied in detail. Four columns located in the basement of this nine-story reinforced concrete building have suddenly started to crack and fracture. At this stage, the authors were invited to the building for investigation during which initiation of another column failure was observed. After securing the building, concrete test samples were taken from each floor. The building is then modeled in 3D using a finite element software. A series of analyses have been carried out based on some reasonable assumptions. The demand-to-capacity ratios for each structural member were determined and a vertical incremental nonlinear pushover analysis was performed so that the possible failure mechanisms could be determined. The results indicated that the limited reserve capacity of columns and variation in material properties led to the observed failure.

Evaluation of performance based displacement limits for reinforced concrete columns under flexure Solmaz, Taylan; Yakut, Ahmet; Department of Civil Engineering (2010) Reinforced concrete frame buildings are the most common type of constructions in Turkey which are exposed to various types of forces during their lifetime. Seismic performance of reinforced concrete frame buildings is dominated by columns which can be classified as primary members of these structures. When current codes are considered, all of them contain several provisions in order to implement reliable seismic performances of reinforced concrete columns. In order to evaluate the accuracy of these provisio...
Evaluation of the Predictive Models for Stiffness, Strength, and Deformation Capacity of RC Frames with Masonry Infill Walls Turgay, Tahsin; Durmus, Meril Cigdem; Binici, Barış; Ozcebe, Guney (American Society of Civil Engineers (ASCE), 2014-10-01) Buildings with masonry infill walls (MIWs) in reinforced concrete (RC) frames are commonly used all around the world. It is well known that infill walls may affect the strength, stiffness, and displacement ductility of the structural system. Different approaches have been adopted in different codes and guidelines to consider the stiffness and strength contribution of MIWs on RC frame behavior. This study compares the ability of the existing guidelines to estimate stiffness, strength, and deformability of RC...
Effects of masonry infill walls on the seismic performance of buildings Öztürk, Mehmet Selim; Akyüz, Uğurhan; Department of Civil Engineering (2005) In Turkey, in most of the reinforced concrete buildings, hallow masonry infill walls are used as a non-structural element, during design stage, their contribution to overall building behavior is not well known. Observations made after the earthquakes revealed that these non-structural elements had beneficial effects on the lateral capacity of the building. In this study, the contribution of the hallow masonry infill walls to the lateral behavior of reinforced concrete buildings was investigated. For this pu...
Performance-based seismic rehabilitation of damaged reinforced concrete buildings Sucuoğlu, Haluk; Gunay, MS (American Society of Civil Engineers (ASCE), 2004-10-01) A building stock consisting of 130 medium-rise reinforced concrete buildings were damaged moderately during the recent earthquakes in Turkey. These buildings were rehabilitated by using simple, cost-effective methods where the newly added shear walls comprised the primary lateral load resisting system. In the presented study, different seismic performance evaluation procedures are tested first on the samples of damaged buildings for predicting their observed performances. Then the expected performances of t...
A comparative study on earthquake resistance of reinforced concrete and masonry residential buildings in small-scale cities of Turkey Er Akan, Aslı; Ünay, Ali İhsan; Department of Building Science in Architecture (2008) Today the vast majority of urban population in Turkey is living in multi-story apartment blocks constructed of reinforced concrete due to the fact that in the late 19th century concrete and steel took the place of traditional materials such as masonry. However, it cannot be denied that masonry is still a crucial material for load bearing walls, internal walls and cladding of buildings. In addition to this masonry construction system has many advantages. From the architectural point of view, it provides flex...
