The main objective of the SERAMAR project has been to utilize current tools for earthquake risk assessment and to establish a unique partnership between universities, professional associations, and local governments, which might serve as a model for similar future activities in Turkey and adjacent areas. In order to reach this goal, a thorough microzonation survey program combined with vulnerability and social preparedness studies in anticipation of a damaging seismic event were conducted. The paper is focused on activities related to surveying building stock and classifying and evaluating through the use of different levels of consideration. Empirical risk scenarios and casualty estimations are carried out for different levels of consideration under scenario earthquakes similar in size to historic events. Preliminary findings of the pilot phase are reported in terms of credible building performance and casualty estimates. For empirical studies, the building vulnerabilities are expressed in terms of vulnerability classes of EMS-98.
ÖzMaksimum göreli kat ötelemeleri, yapıların yönetmeliklerce güvenlik açısından sınırlandırıldığı temel parametrelerden biridir. Ülkemizde halen yürürlükte bulunan 2007 Deprem Bölgelerinde Yapılacak Binalar Hakkında Yönetmeliğe göre, elde edilen göreli kat ötelemelerinin sınırları ve kriterleri, 2016 Türkiye Bina Deprem Yönetmelik taslağı ile değişmektedir. Bu çalışmada, her iki yönetmeliğin "Etkin Göreli Kat Öteleme" hesabı ve sınır şartları detaylı olarak karşılaştırılmıştır. Taslak yönetmelikte izin verilen göreli kat öteleme sınırlarının, dolgu duvar -çerçeve bağlantısının derzsiz olduğu durum için genel olarak illerin büyük çoğunluğunda arttığı, derzli tasarımda ise derzsize göre iki kat yükseldiği anlaşılmaktadır.Anahtar Kelimeler: Göreli kat ötelemesi, TBDY2016, Elastik tasarım spektral ivmesi
Comparison of Reduced Relative Storey Drifts According to Current Earthquake Code (DBYBHY2007) and New Draft Earthquake Code (TBDY2016) AbstractMaximum relative floor displacements are one of the basic parameters that are limited by the regulations in terms of safety for the regulations. According to the Regulation on the Turkish Earthquake Code (TEC) 2007 which are currently in force in our country, the limits and criteria of the relative floor drifts obtained vary according to the TEC 2016 in draft. In this study, the "Effective Relative Floor Shift" account and boundary conditions of both directives are compared in detail. It is understood that the permissible floor folding limits allowed in the draft regulation are increased in the majority of the cases in general, in case of the joint of the filler wall-frame joint, and in the case of the jointed design, two times higher than the joint.
<p>This manuscript presents a site response analysis and an estimation of S-wave velocity that are dependent on acceleration data. First, existing data, such as density, seismic wave velocity, and soil cross-sections, are obtained from previous seismic microzonation studies and used to prepare input data for a suite of MATLAB routines, which are referred to as SUA software. Acceleration data are obtained from four free-field strong-motion stations of the SERAMAR project, which was conducted between 2006 and 2009 in conjunction with a Turkish-German joint research project, and inputted into the software as basic data. The results include a 1D velocity cross-section versus depth and an amplification model of the site. Three different depth levels can be determined for the ranges of 0-5 m, 5-15 m and 15-25 m. The seismic velocities vary between 380 and 470 m s-1 for the first 5 m; 320 and 480 m s-1 for 5-15 m; and 470 and 750 m s-1 for 15-25 m. These results are comparable with the amplification values from the microtremor data from previous studies. The 1D velocity models are appropriate for the soil conditions.</p><p><strong><br /></strong></p><p><strong>Resumen</strong></p><p>Este trabajo presenta el análisis a una respuesta de sitio y una estimación de la velocidad de la onda de corte que son dependientes de la información de aceleración. Los datos adicionales como la densidad, la velocidad de onda sísmica y los cortes transversales de suelo, se obtuvieron de estudios previos de microzonificación sísmica y se utilizaron para preparar el registro de datos en una plataforma de rutinas MATLAB, que se refieren al software SUA. Los datos de información de la aceleración se tomaron de cuatro estaciones de monitoreo de movimientos fuertes a campo abierto del proyecto SERAMAR, que se realizó entre 2006 y 2009 en una investigación conjunta turco-alemana, y se ingresaron en el programa como la información básica. Los resultados incluyen una sección cruzada de velocidad 1D versus profundidad y el modelo amplificado del sitio. Se pudieron determinar tres niveles diferentes a partir de los rangos de 0-5 m, 5-15 m y 15-25 m. Las velocidades sísmicas pueden variar entre 380 y 470 m s-1 para los primeros 5 metros; 320 y 480 m s-1 para el rango 5-15 m, y 450 y 750 m s-1 para el rango 15-25 m. Estos resultados son comparables con los valores de amplificación del perfil Microtemor de estudios previos. Los modelos de velocidad 1D son apropiados para las condiciones del suelo.</p>
