“…When the level of accuracy and required information is considered, the second type of rapid evaluation methods seems promising. Therefore Ozcebe (2004), Yakut (2004), and P25 (Bal et al, 2006), which are all second type methods, are selected to be examined in the scope of this study. These are developed by information on Turkish building stock, which is in accordance with the damage data used.…”

“…The damage data collected after the 19 May 2011 Simav (Turkey) earthquake are used to examine the correlation with rapid evaluation method scores proposed previously by researchers (Ozcebe, 2004;Yakut, 2004;Bal et al, 2006). The conclusions of this study may be useful for the further development of such methods and understanding the effects of seismic events on buildings.…”

“…There are many rapid evaluation methods developed for use in seismic evaluation (FEMA-154, 1988;Japan Seismic Index -Ohkubo, 1991;FEMA-310, 1998;FEMA-154, 2002;Ozcebe, 2004;Yakut, 2004;Bal et al, 2006). These various methods for the vulnerability assessment of buildings differ in expenditure and precision.…”

A major portion of the existing Turkish building stock consists of seismically deficient buildings, like in many other earthquake-prone developing countries. For the mitigation of the damage before an earthquake, the seismic evaluation of the existing building stock is the first step. However, the great number of buildings to be evaluated is an obstacle for the detailed assessment. Rapid evaluation methods are developed to minimize the need of resources for the evaluation of the buildings in great numbers. In this study, performances of the rapid evaluation methods to estimate seismic damage are investigated by examining the correlation between the rapid evaluation method scores and the quantified damage states after the 19 May 2011 Simav (Turkey) earthquake. A total of 144 reinforced concrete buildings are carefully examined in terms of the properties of structural system, architectural layout, concrete strength, soil conditions and damage state. The correlation of rapid evaluation methods with the observed damage happened to be low. It is concluded that, if the building damage state is determined by the local brittle damages in members, the estimations with the rapid evaluation methods may diverge from the actual scene after an earthquake

“…Besides, it could be very difficult or even impossible for a huge building stock to perform such an analysis. For this reason, many rapid assessment methods that can determine the seismic risk of structures without detailed analytical studies were developed (Shiga et al, 1968;Bresler, 1977;FEMA 155, 1988;Ohkubo, 1990;NRCC, 1993;Gulkan and Sozen, 1999;Lang, 2002;Yakut, 2004;Xavier et al, 2006;Gulay et al, 2008). In order to develop such a rapid assessment method, a building stock with a specific character is mainly used and the developed method reflects the characteristics of this specified stock.…”

Abstract. Different levels of damages occurred in state buildings, especially in educational facilities, during the Simav earthquake (M L = 5.7) on 19 May 2011. A site survey was carried out in the area after the earthquake, where six state buildings were examined in detail. The results of the survey showed that main reasons for the formation of damages in these buildings are the use of low strength concrete, insufficient reinforcement, inappropriate detailing, and low-quality workmanship. The investigated buildings were also evaluated by P25-rapid assessment method. The method demonstrates that two of the buildings in question are in "high risk band"; the other two fall into "detailed evaluation band", and the rest are in the "low risk band". This figure also matches with the damages observed in the site survey.

Current research study consists of determining the optimum location of the shear wall to get the maximum structural efficiency of a reinforced concrete frame building. It consists of a detailed analysis and design review of a seven-story reinforced concrete building to understand the effect of shear wall location on the response of reinforced concrete structures when subjected to different earthquake forces. Three trail locations of shear walls are selected and their performance is monitored in terms of structural response under different lateral loads. Required objectives are achieved by obtaining design and construction drawings of an existing reinforced concrete structure and modeling it on Finite Element Method (FEM) based computer software. The structure is redesigned and discussed with four different configurations (one without shear wall and three with shear walls). Main framing components (Beams, Columns and Shear walls) of the superstructure are designed using SAP 2000 V. 19.0 whereas substructure (foundation) of RC building was designed using SAFE. American Concrete Institute (ACI) design specifications were used to calculate the cracked section stiffness or non-linear geometrical properties of the cracked section. Uniform Building Code (UBC-97) procedures were adopted to calculate the lateral earthquake loading on the structures. Structural response of the building was monitored at each story level for each earthquake force zone described by the UBC-97. The earthquake lateral forces were considered in both X and Y direction of the building. Each configuration of shear wall is carefully analyzed and effect of its location is calibrated by the displacement response of the structure. Eccentricity to the lateral stiffness of the building is imparted by changing the location of shear walls. Results of the study have shown that the location of shear wall significantly affects the lateral response of the structure under earthquake forces. It also motivates to carefully decide the center of lateral stiffness of building prior to deciding the location of shear walls.
