Performance-based seismic rehabilitation of damaged reinforced concrete buildings

A building stock consisting of 130 medium-rise reinforced concrete buildings were damaged moderately during the recent earthquakes in Turkey. These buildings were rehabilitated by using simple, cost-effective methods where the newly added shear walls comprised the primary lateral load resisting system. In the presented study, different seismic performance evaluation procedures are tested first on the samples of damaged buildings for predicting their observed performances. Then the expected performances of the rehabilitated buildings are evaluated by employing these procedures. It has been found that the nonlinear static procedure is equally successful as the nonlinear dynamic procedure in predicting the observed performances of damaged buildings. The demand-to-capacity ratios obtained from linear spectral procedure are also good indicators of member performances predicted by the nonlinear static procedure. The predicted performance of the rehabilitated buildings evaluated under design excitations revealed that the simple rehabilitation methodology applied systematically should provide life safety under a 475 year seismic hazard. Hence, implementation of the cost effective rehabilitation method presented herein can be suggested as a realistic solution for the vulnerable medium rise concrete buildings in seismic regions.

There is a damage potential for the columns of building frames due to either unexpected causes such as vehicle impact, boiler explosion, or terrorist attack, or due to design or construction deficiencies aggravated by an earthquake, severe wind, or excessive foundation movement. This paper investigates the redistribution paths of released forces resulting from a column failure and identifies the basic structural defense mechanisms developed in a damaged building frame. Extensive analytical studies revealed ...
Seismic risk assessment of gravity load designed reinforced concrete frames subjected to mid-America ground motions
Çelik, Ozan Cem (American Society of Civil Engineers (ASCE), 2009-03-24)
The infrequent nature of earthquakes in the Central and Eastern United States (CEUS), and the fact that none with intensity comparable to the New Madrid sequence of 1811-12 has occurred in the past century, have caused the earthquake hazard in the CEUS to be neglected until quite recently. The performance of reinforced concrete (RC) frames in the CEUS may be deficient if they are subjected to earthquakes that are believed to be plausible in the New Madrid Seismic Zone (NMSZ). This study presents a set of pr...
Cost-benefit analysis for various rehabilitation strategies
Çetinceli, Serkan; Yakut, Ahmet; Department of Civil Engineering (2005)
Over the last decade, six major earthquakes that occurred in Turkey dramatically demonstrated the poor performance of the buildings that were designed and constructed far from Turkish seismic code̕s requirements. The Marmara region, where most of the population and industry is located, is in the active seismic zone. With the rising cost of damages due to earthquakes, the necessity of the cost-benefit analysis for various rehabilitation strategies used in existing buildings has become a major concern for the...
Seismic strengthening of masonry infilled reinforced concrete frames with steel-fibre-reinforced mortar

In addition to high seismicity, poor construction quality, incorrect detailing and structural mistakes in Turkey have caused enormous loss of life and property. Therefore, seismic rehabilitation has been a major topic for civil engineers in Turkey. The object of this research is to develop a simple method that will provide strengthening of buildings without evacuating the inhabitants. This study is based on application of steel-fibre-reinforced mortar on masonry infill walls with the aim of converting nonst...
Mechanical properties of cfrp anchorages
Özdemir, Gökhan; Akyüz, Uğurhan; Department of Civil Engineering (2005)
Due to inadequate lateral stiffness, many reinforced concrete buildings are highly damaged or collapsed in Turkey after the major earthquake. To improve the behavior of such buildings and to prevent them from collapse, repair and/or strengthening of some reinforced concrete elements is required. One of the strengthening techniques is the use of CFRP sheets on the existing hollow brick masonry infill. While using the CFRP sheets their attachment to both structural and non-structural members are provided by C...
