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 exposing the structure to a set of ground motions scaled by taking reference from the California region in the USA. The effect of different parameters of the designed building was considered in the study such as a) the story height b) the number of bays c) the presence of shear walls d) the addition of dampers and different damping pa- rameters. In addition, the NTHA was repeated for different ground motion intensity levels.

Experimental investigation on seismic behavior of eccentric reinforced concrete beam-column-slab connections
Canbolat, Burcu B.; Wight, James K. (2008-03-01)
Design recommendations for reinforced concrete beam-column connections are based on limited experimental studies on the seismic behavior of eccentric connections. To supplement existing information, an experimental study was conducted that focused on the affect of eccentricity of spandrel beams with respect to the column. Specimens included a floor slab and transverse beams to evaluate the effect of slab participation. Test results indicated that including the floor system significantly reduced the negative...
Performance Assessment of Turkish Residential Buildings for Seismic Damage and Loss Estimation
Un, Elif M.; Erberik, Murat Altuğ; Askan Gündoğan, Ayşegül (2015-04-01)
This study aims to present an integrated method in a probabilistic manner for seismic performance assessment of Turkish residential buildings, which can be used as a tool to estimate earthquake losses due to structural damage. In particular, the objective is to determine the performances of different types of residential buildings for predicting the potential seismic loss in terms of casualties (death toll) for a highly populated city in northwestern Turkey. The main phases of this study are seismic hazard,...
Analytical study on seismic retrofitting of reinforced concrete buildings using steel braces with shear link
Durucan, Cengizhan; Dicleli, Murat (2010-10-01)
This paper is focused on a proposed seismic retrofitting system (PRS) configured to upgrade the performance of seismically vulnerable reinforced concrete (RC) buildings. The PRS is composed of a rectangular steel housing frame with chevron braces and a yielding shear link connected between the braces and the frame. The retrofitting system is installed within the bays of an RC building frame to enhance the stiffness, strength and ductility of the structure. The PRS and a conventional retrofitting system usin...
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...
An improvement to linear-elastic procedures for seismic performance assessment
Gunay, Mehmet Selim; Sucuoğlu, Haluk (Wiley, 2010-07-10)
An improved linear-elastic analysis procedure is developed in this paper as a simple approximate method for displacement-based seismic assessment of the existing buildings. The procedure is mainly based on reducing the stiffness of structural members that are expected to respond in the inelastic range in a single global iteration step. Modal spectral displacement demands are determined from the equal displacement rule. Response predictions obtained from the proposed procedure are evaluated comparatively by ...
