The seismic response of infilled frames draws considerable interest in the earthquake engineering community for the last decades. Whilst the early studies were concerned with added lateral stiffness and strength, recent studies focused primarily on deformability and performance improvement. In this study, an experimental campaign was conducted to investigate the seismic performance of ductile reinforced concrete (RC) frames infilled with hollow clay bricks and autoclaved aerated concrete blocks. The effectiveness of different infill wall construction techniques, such as the use of isolation joints, mesh overlays, and horizontal sliding joints were evaluated by carrying out cyclic tests on seven half-scale RC frame specimens. Strength and stiffness degradation, energy dissipation and damage propagation of tested infill wall systems obtained by deducing bare frame (BF) response from the infilled frame (IF) were compared. Damage limit states in terms of story drift were proposed based on specific points located on the normalized experimental load-displacement backbone of infill walls. A detailed description of physical damage corresponding to each damage state was reported for visual quantification of the infill wall performance.

Evaluation of Changing Building Characteristics in Turkey Ay, Bekir Özer; Erberik, Murat Altuğ (2016-09-23) Seismic risk combines earthquake induced hazard with structural response and determines loss that is equaled or exceeded over some time period. In this sense, it is of prime importance to utilize proper earthquake loss models that are able to consider local characteristics of building stock in a realistic way. The aim of this study is to compile changing characteristics of Turkish buildings that is believed to be necessary to develop representative models for loss estimations. Accordingly, a statistical sur...
THE EFFECT OF HORIZONTAL IRREGULARITIES AND BASE ISOLATION CONFIGURATION ON SEISMIC RESPONSE OF RC BUILDINGS Yazıcıoğlu, Eylem Bilge; Caner, Alp; Dicleli, Murat; Department of Earthquake Studies (2022-2-22) This study aims to evaluate the effect of horizontal irregularities and base isolation configuration on the seismic response of reinforced concrete base-isolated buildings. A set of structural models with varying re-entrant corner geometric properties has been utilized to make evaluations with respect to square-symmetric ordinary form. In addition to this set, alternative models with non-uniform mass distributions in the plan have also been employed to expand the building set. Elastic response spectrum-base...
Comparative study of base isolated systems Türkmen, Fatih; Akyüz, Uğurhan; Department of Civil Engineering (2002) This thesis is mainly concerned with providing brief knowledge about the effects of earthquakes on buildings and their response to earthquake forces. Principles of advanced passive earthquake resistant design techniques are also presented. Next, the use of the most common passive earthquake resistant design technique; i.e., base isolation is described, with its historical background, main principles and usage in the world. In order to evaluate the effectiveness of base isolation, and the performance of base...
Evaluation of the site effects of the Ankara basin, Turkey Kockar, M. K.; Akgün, Haluk (2012-08-01) Recent major earthquakes have explicitly demonstrated that near-surface local site conditions that can generate significant amplifications and spatial variations of earthquake ground motion play a major role in the level of ground shaking and in gathering information on soft soil response. It is therefore highly desirable to develop methods to identify and characterize regions that are prone to this type of site amplification. To determine the subsurface sediment characteristics over a wide area, measuremen...
The depth effect of earthquakes on tsunami heights in the Sea of Okhotsk Zaytsev, Andrey; Kostenko, Irina; Kurkin, Andrey; Pelinovsky, Efim; Yalçıner, Ahmet Cevdet (The Scientific and Technological Research Council of Turkey, 2016-01-01) The earthquake of magnitude M-w = 8.3 that occurred on 24 May 2013 in the Sea of Okhotsk was the most powerful earthquake in the region. Fortunately, the generated tsunami was small because of the deep focal depth (609 km) and was only detected by the nearest Deep-ocean Assessment and Reporting of Tsunamis (DART) buoy records. However, the event highlighted the fact that any earthquakes with similar magnitudes at shallower focal depths would have caused considerable tsunamis. In order to evaluate the effect...
