A pair of half-scale, three-story, three-bay concrete bare frames were tested by the pseudo-dynamic (PsD) testing procedure. Both frames represent common deficiencies. of non-seismic construction. Continuous column reinforcement in one specimen and insufficient lap splices at the bottom ends of columns in the other specimen were the only significant differences. Measured seismic performances of both frames were assessed by using the rotation and strain-based acceptance criteria of two different seismic codes. Dynamic responses of both frames were also predicted by employing nonlinear frame models. Analytical models of deficient frames were capable of predicting global deformation response, but failed to predict local deformations. Prediction of local deformations in deficient frames can only be improved if joint deformations and hysteretic degradation in member properties are considered directly in the analytical models.

Pseudo-Dynamic Testing and Analytical Modeling of AAC Infilled RC Frames Sucuoğlu, Haluk (2014-01-01) Two concrete frames were tested by the PsD procedure. One frame was bare and the other was infilled with AAC blocks in the middle bay. The objective was to determine the effect of AAC infills on the seismic performance of reinforced concrete frames and developing an AAC strut model. Based on the test results, it was found that AAC infill panels did not modify the deformation response of the RC test frame significantly; however, shear in diagonal strut must be considered in boundary column design. A shear de...
Pseudo Dynamic Testing of an RC Frame Retrofitted with Chevron Braces ÖZÇELİK, RAMAZAN; Binici, Barış; Kurç, Özgür (2012-01-01) Two-story three-bay reinforced concrete frames with and without chevron brace was tested using pseudo dynamic test method. The chevron braces were implemented to the interior span of the RC frame. Chevron-braced frame was observed to be effective to control inter-story drift demands. Based on the observed damage state and dynamic response of the test frames, performance states were discussed for different scales of Duzce ground motions. The test results were compared with the results of the nonlinear time h...
Experimental evaluation of the in-plane behaviour of masonry wall infilled RC frames Suzuki, Tomomi; Choi, Ho; Sanada, Yasushi; Nakano, Yoshiaki; Matsukawa, Kazuto; Paul, Devjyoti; Gulkan, Polat; Binici, Barış (2017-10-01) This study focuses on the in-plane behaviour of unreinforced masonry (URM) infill walls installed in reinforced concrete (RC) frames. Five 1/4-scale model frames were designed based on a prototype RC building with URM infill walls in Turkey. The experimental parameters were the layout of the URM infill (its presence or absence), number of spans (single or double), number of stories (single or double), and stacking pattern of the URM infill (horizontal or vertical). Static cyclic loading tests were conducted...
Pseudo dynamic test of a deficient reinforced concrete frame upgraded with internal steel frames ÖZÇELİK, RAMAZAN; Binici, Barış; Kurç, Özgür (2013-04-01) Two-story, three-bay reinforced concrete (RC) frames with and without internal steel frame (ISF) retrofits were tested using continuous pseudo dynamic test method. The ISFs were installed to the middle bay of the RC frame. Test results indicated that ISF retrofit was beneficial in resisting deformation demands without significant damage under simulated ground motions. The ISF shifted the failure mode of the system from a brittle to a ductile mode. The test results were compared with the results of the nonli...
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...
