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 Damage Plasticity (CDP) model was used to capture nonlinearities in concrete under cyclic loading. Good agreement was achieved between experimental and numerical results, which indicates that the finite element model is capable of capturing failure modes of the investigated precast connections. Agreement between the experimental and numerical behaviors was valid in terms of both the global load–displacement response as well as the local response, such as the force within connection rods and the beam curvature. Behavior of the precast concrete connection was influenced significantly by the anchorage detail used for steel connection plates and the beam reinforcement detailing in the vicinity of the connection. Simple detailing modifications resulted in major improvements in the performance of connection in terms of strength, stiffness and energy dissipation characteristics.

Cyclic behaviour of precast beam-to-column connections: An experimental and numerical investigation Torra-Bilal, Ines; Mahamid, Mustafa; Baran, Eray (2022-01-01) 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 specime...
Joint shear strength prediction for reinforced concrete beam-to-column connections Unal, Mehmet; Burak Bakır, Burcu (2012-02-10) In this analytical study numerous prior experimental studies on reinforced concrete beam-to-column connections subjected to cyclic loading are investigated and a database of geometric properties, material strengths, configuration details and test results of subassemblies is established. Considering previous experimental research and employing statistical correlation method, parameters affecting joint shear capacity are determined. Afterwards, an equation to predict the joint shear strength is formed based o...
Performance Examination of Two Seismic Strengthening Procedures by Pseudodynamic Testing Kurt, Efe Gokce; Kurç, Özgür; Binici, Barış; Canbay, Erdem; Ozcebe, Guney (American Society of Civil Engineers (ASCE), 2012-01-01) Pseudodynamic testing was employed to observe the seismic performance of two retrofit methods on two-story, three-bay frame structures. The test frames had hollow clay tile (HCT) infill in the central bay and incorporated the seismic deficiencies of Turkish construction practice, such as use of plain reinforcing bars, low-strength concrete, and insufficient confining steel. Two noninvasive and occupant-friendly retrofit schemes suggested in the Turkish Earthquake Code, namely, use of fiber-reinforced polyme...
Contribution of reinforced concrete infills to seismic behavior of structural systems Canbay, Erdem; Ozcebe, G (2003-09-01) The object of this paper is to report an experimental investigation on the internal force distribution in reinforced concrete (RC) frames with added RC walls. The paper describes a special test setup and force transducers designed to determine the internal forces. The transducers were designed so that the stiffness change in the column would be minimal. The paper reports the results of a test in which a 1/3-scale, two-story, three-bay RC frame was first subjected to damaging lateral-drift reversals and was ...
Plastic rotation capacity of RC columns under biaxial seismic demands Özcan, Okan; Binici, Barış (2023-03-01) Seismic performance of reinforced concrete (RC) columns should be evaluated considering biaxial demands for a more realistic assessment. However, most of the current seismic assessment regulations stipulate rotation capacity estimations considering only uniaxial bending test database. The effect of seismic demands in one direction may have a detrimental effect in the deformation capacity of the other direction. In the past studies, the influence of biaxial loading patterns/paths/histories, axial load level,...
