Pseudo-Dynamic Testing, Performance Assessment, and Modeling of Deficient Reinforced Concrete Frames

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...

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...
Seismic performance of gravity-load designed concrete frames infilled with low-strength masonry
Siddiqui, Umair A.; Sucuoğlu, Haluk; Yakut, Ahmet (2015-01-01)
This study compares the seismic performances of two reinforced concrete frame specimens tested by the pseudo-dynamic procedure. The pair of 3-storey, 3-bay frames specimens are constructed with typical characteristics of older construction which is lacking seismic design. One of the specimens is a bare frame while the other is infilled with low-strength autoclave aerated concrete (AAC) block masonry. The focus of this study is to investigate the influence of low strength masonry infill walls on the seismic ...
Pseudo-dynamic testing of a concrete gravity dam
Aldemir, Alper; Binici, Barış; Arıcı, Yalın; Kurç, Özgür; Canbay, Erdem (2015-09-01)
Inspired from the simplified single degree of freedom modeling approach used in the preliminary design of concrete gravity dams, a pseudo-dynamic testing method was devised for the seismic testing of a concrete gravity dam section. The test specimen was a 1/75 scaled section of the 120-m-high monolith of the Melen Dam, one of the highest concrete gravity dams to be built in Turkey. The single degree of freedom idealization of the dam section was validated in the first stage of the study using numerical simu...
