Vulnerable buildings and their rehabilitation are important problems for earthquake regions. In recent decades the goal of building rehabilitation and strengthening has gained research attention and numerous techniques have been developed to achieve this. However, most of these strengthening techniques disturb the occupants, who must vacate the building during renovation. In this study, a new strengthening alternative for RC structures, namely exterior shear walls, has been experimentally investigated under reversed cyclic loading. Using the proposed technique, it is possible to strengthen structures without disturbing their users or vacating the building during renovation. In this technique, shear walls are installed in parallel to the building's exterior sides. It has been observed that the usage of exterior shear walls considerably improve the capacity and sway stiffness of RC structures. The experimental results have also been compared and found to be in agreement with the numerical solutions. Post attached exterior shear walls behaved as a monolithic member of the structure. Design considerations for the exterior shear wall-strengthened buildings have also been discussed in the paper.

Seismic fragilities for non-ductile reinforced concrete frames - Role of aleatoric and epistemic uncertainties Çelik, Ozan Cem (2010-01-01) Seismic fragilities are essential to earthquake loss estimation and performance-based earthquake engineering in regions of high seismicity. Construction practices for frames in regions of moderate seismicity are quite different, and such frames have received less attention in the literature. Fragilities for performance levels identified in recent seismic regulations are developed herein for reinforced concrete frames designed for gravity load in low-seismic regions using probabilistic non-linear finite elem...
Structural rehabilitation of damaged RC buildings after the 1 october 1995 Dinar earthquake Wasti, ST; Sucuoğlu, Haluk; Utku, M (2001-04-01) This paper contains technical information related to the Dinar project for the rehabilitation of moderately damaged reinforced concrete buildings after the 1 October 1995 Dinar earthquake. The structural appraisal of the damaged buildings, analytical studies leading to decisions regarding structural rehabilitation or demolition, the supervision on site of the rehabilitation and the overall coordination of the project was entrusted to the Middle East Technical University Earthquake Engineering Research Cente...
Seismic performance evaluation of reinforced concrete frames infilled with autoclave aerated concrete masonry Siddiqui, Umair Ahmed; Sucuoğlu, Haluk; Yakut, Ahmet; Department of Earthquake Engineering and Engineering Seismology (2013) Seismic risk reduction requires detailed assessment and rehabilitation of vulnerable buildings to avoid significant property and life losses. Several reinforced concrete buildings are deficiently designed and constructed and also contain non-engineered unreinforced masonry infill panels which dominate the seismic response and impart excessive lateral forces for which they are not designed for. Therefore, seismic performance assessment procedures recommended in guidelines and codes needs detailed examination...
Seismic vulnerabilities and risks for urban mitigation planning in Turkey Sönmez Saner, Tuğçe; Ersoy, Melih; Balamir, Murat; Department of City and Regional Planning (2013) Chronic seismic hazards and resulting secondary impacts as natural conditions of the country, and loss of robust building and prudent settlement practices as aggravated by rapid population growth make cities the most vulnerable geographical and social entities in Turkey. In contrast, Turkish disaster policy is solely focused on post-disaster issues and no incentives or provision exist to encourage risk analysis or risk mitigation approaches, despite current international efforts. For the development of risk...
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...
