The main objective of this study is to examine the behavior of hybrid beam-column connections with numerous detailing methods to be incorporated in precast moment resisting frames under simulate reversed cyclic loading, which will lead to better understanding of their performance and safer seismic applications. To accomplish the research objectives, an integrated experimental and numerical study was conducted. The experimental part consisted of reversed cyclic loading of precast concrete beam-column specimens with six different anchorage details used in beam element, as well as monolithically cast companion specimens. In the numerical part, a nonlinear finite element analysis (FEA) approach was proposed to reproduce the experimental response of a specific type of moment resisting precast concrete beam-column connection exposed to reversed cyclic load tests. To prove the validity of the proposed finite element approach, three-dimensional (3D) finite element models were built using ABAQUS, a nonlinear finite element analysis tool, for a reference monolithic and various precast hybrid beam-column connections. The models intend to lead to comprehensive investigation of concrete and steel behavior reaching failure. A modified Concrete Damage Plasticity model (CDP) that accounts for compression-softening and tension-stiffening effect was adopted for concrete in order to reproduce the typical cyclic behavior of cracked reinforced concrete. Kinematic Bilinear Elasto-Plastic nonlinear model was used to model all steel parts with the addition of bond-slip effect for all reinforcing bars embedded in concrete.

Baran, Eray; BARAN, MEHMET; Kurtoglu, Metin; Torra-Bilal, Ines (2021-11-01)
Seismic performance of a specific type of moment resisting precast concrete beam-column connection was investigated through reversed cyclic load tests. Structural steel components were incorporated with precast concrete beam and column elements in the experiments to provide a ductile moment resisting connection. Additionally, nonlinear finite element analysis (FEA) of typical monolithic and precast connections was performed to investigate the performance and failure modes of these connections. Concrete Dama...
Parameter optimization of steel fiber reinforced high strength concrete by statistical design and analysis of experiments
Ayan, Elif; Saatçioğlu, Ömer; Department of Industrial Engineering (2004)
This thesis illustrates parameter optimization of compressive strength, flexural strength and impact resistance of steel fiber reinforced high strength concrete (SFRHSC) by statistical design and analysis of experiments. Among several factors affecting the compressive strength, flexural strength and impact resistance of SFRHSC, five parameters that maximize all of the responses have been chosen as the most important ones as age of testing, binder type, binder amount, curing type and steel fiber volume fract...
Nonlinear system identification and nonlinear experimental modal analysis by using response controlled stepped sine testing
Karaağaçlı, Taylan; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2020-12-24)
In this work, two novel nonlinear system identification methods are proposed in both the modal and spatial domains, respectively, based on response-controlled stepped-sine testing (RCT) where the displacement amplitude of the excitation point is kept constant throughout the frequency sweep. The proposed nonlinear modal identification method, which is also a nonlinear experimental modal analysis technique, applies to systems with several nonlinearities at different (and even unknown) locations (e.g. joint no...
Experimental Study on Seismic Strengthening of Reinforced Concrete Frames by Precast Concrete Panels
BARAN, MEHMET; Tankut, Tugrul (2011-03-01)
The purpose of this study is to investigate the behavior of reinforced concrete (RC)frames under cyclic loads strengthened by using precast concrete (PC) panels. The idea is to transform the existing hollow brick infills into strong and rigid infills by bonding relatively high-strength PC panels with a thin layer of epoxy mortar By this method, the seismic behavior of the frame is improved. For this purpose-one being reference-a total of 11 one-third scale, one-hay, two-story deficient RC frames were tested...
Nonlinear resonances of axially functionally graded beams rotating with varying speed including Coriolis effects
Lotfan, Saeed; Anamagh, Mirmeysam Rafiei; Bediz, Bekir; Ciğeroğlu, Ender (2021-11-01)
The purpose of the current study was to develop an accurate model to investigate the nonlinear resonances in an axially functionally graded beam rotating with time-dependent speed. To this end, two important features including stiffening and Coriolis effects are modeled based on nonlinear strain relations. Equations governing the axial, chordwise, and flapwise deformations about the determined steady-state equilibrium position are obtained, and the rotating speed variation is considered as a periodic distur...
