Pseudo-Dynamic Testing and Analytical Modeling of AAC Infilled RC Frames

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 design procedure is proposed for the boundary columns in infilled frames. The drift limits of AAC infill panels measured during the tests were 0.005, 0.008, and 0.014 during diagonal cracking, corner crushing, and severe damage states, respectively.


Pseudo-Dynamic Testing, Performance Assessment, and Modeling of Deficient Reinforced Concrete Frames
Sucuoğlu, Haluk; Binici, Barış (2014-09-01)
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 code...
Optimum design of reinforced concrete plane frames using harmony search algorithm
Akın, Alper; Saka, Mehmet Polat; Department of Engineering Sciences (2010)
In this thesis, the optimum design algorithm is presented for reinforced concrete special moment frames. The objective function is considered as the total cost of reinforced concrete frame which includes the cost of concrete, formwork and reinforcing steel bars. The cost of any component is inclusive of material, fabrication and labor. The design variables in beams are selected as the width and the depth of beams in each span, the diameter and the number of longitudinal reinforcement bars along the span and...
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...
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...
Nonlinear analysis of reinforced concrete frame structures
Çiftçi, Güçlü Koray; Polat, Mustafa Uğur; Department of Civil Engineering (2013)
Reinforced concrete frames display nonlinear behavior both due to its composite nature and the material properties of concrete itself. The yielding of the reinforcement, the non-uniform distribution of aggregates and the development of cracks under loading are the main reasons of nonlinearity. The stiffness of a frame element depends on the combination of the modulus of elasticity and the geometric properties of its section - area and the moment of inertia. In practice, the elastic modulus is assumed to be ...
