This paper reports the structural rehabilitation of a 28 story reinforced concrete building. Structural assessment of this building was initiated upon observing damage in one column after five years of service. As a result of this investigation it was concluded that the main cause of damage in the column was temperature induced deformations. A total of 36 circular (spiral) and 46 square (tied) columns were strengthened by steel jacketing. After the completion of rehabilitation, 122 sensors were placed in the building at different locations to monitor the temperature changes and deformations in structural members. In the paper results of seven years of monitoring are also given.

COMPARATIVE ASSESSMENT OF THE SEISMIC PERFORMANCE OF FIXED BASE AND ROCKING BUILDING FRAMES EQUIPPED WITH AN ENERGY DISSIPATION SYSTEM
Özen, Hazal; Dicleli, Murat; Department of Engineering Sciences (2023-3-06)
In this study, the effect of columns with a rocking-base isolation system on enhancing the seismic performance of a reinforced concrete building is investigated. A compara- tive study comprising of comparisons of fixed-based and rocking-based systems with post-tensioning strands and free column ends is conducted. For analysis purposes, a reinforced-concrete building with shear walls was designed, modeled, and analyzed in ETABS software. Nonlinear boundary time history analysis (NTHA) was conducted by exposi...
Fragility based assessment of lowrise and midrise reinforced concrete frame buildings in Turkey
Ay, Bekir Özer; Erberik, Murat Altuğ; Department of Civil Engineering (2006)
In this study, structural vulnerability of reinforced concrete frame structures by considering the countryspecific characteristics is investigated to manage the earthquake risk and to develop strategies for disaster mitigation. Lowrise and midrise reinforced concrete structures, which constitute approximately 75% of the total building stock in Turkey, are focused in this fragilitybased assessment. The seismic design of 3, 5, 7 and 9story reinforced concrete frame structures are carried out according to the ...
Seismic upgrading of reinforced concrete frames with structural steel elements
Özçelik, Ramazan; Binici, Barış; Department of Civil Engineering (2011)
This thesis examines the seismic internal retrofitting of existing deficient reinforced concrete (RC) structures by using structural steel members. Both experimental and numerical studies were performed. The strengthening methods utilized with the scope of this work are chevron braces, internal steel frames (ISFs), X-braces and column with shear plate. For this purpose, thirteen strengthened and two as built reference one bay one story portal frame specimens having 1/3 scales were tested under constant grav...
Fragility based assessment of lowrise and midrise reinforced concrete frame buildings in turkey using Düzce damage database
Özün, Ahsen; Erberik, Murat Altuğ; Department of Civil Engineering (2007)
In this study, the seismic fragility assessment of low-rise and mid-rise reinforced concrete frame buildings which constitute approximately 75 % of the total building stock in Turkey is investigated to quantify the earthquake risk. The inventory used in this study is selected from Düzce damage database which was compiled after the devastating 1999 earthquakes in the Marmara region. These buildings are not designed according to the current code regulations and the supervision in the construction phase is not...
