The shear distortions that beam-to-column connections undergo under earthquake loading have a major contribution to the story drift of a structure. However, the connection regions are generally modeled as rigid zones and the inelastic behavior of the joint is not considered in the dynamic analysis. Therefore, the story drifts are underestimated and the seismic performance of a building cannot be assessed properly. In this study, a model that predicts the joint shear strength versus strain relationship is developed. First, an experimental database is constructed and the key parameters that affect the joint behavior are utilized to develop the joint model. Then, nonlinear analyses are carried out by using Perform 3D with and without the joint model and the analytical results are compared with the experimental ones. The results indicated that considering the developed joint model improves the prediction of the overall seismic behavior and member responses.

Analytical modeling of reinforced concrete beam-to-column connections
Ünal, Mehmet; Burak Bakır, Burcu; Department of Civil Engineering (2010)
Prior studies indicated that beam-to-column connections of reinforced concrete (RC) moment resisting frame structures experience considerable deformations under earthquake loading and these deformations have a major contribution to story drift of the building. In current analysis and design applications, however, the connection regions are generally modeled as rigid zones and the inelastic behavior of the joint is not taken into account. This assumption gives rise to an underestimation of the story drifts a...
Experimental investigation on seismic behavior of eccentric reinforced concrete beam-column-slab connections
Canbolat, Burcu B.; Wight, James K. (2008-03-01)
Design recommendations for reinforced concrete beam-column connections are based on limited experimental studies on the seismic behavior of eccentric connections. To supplement existing information, an experimental study was conducted that focused on the affect of eccentricity of spandrel beams with respect to the column. Specimens included a floor slab and transverse beams to evaluate the effect of slab participation. Test results indicated that including the floor system significantly reduced the negative...
Development and analytical verification of an inelastic reinforced concrete joint model
Unal, Mehmet; Burak Bakır, Burcu (Elsevier BV, 2013-07-01)

COMPARATIVE ASSESSMENT OF THE SEISMIC PERFORMANCE OF FIXED BASE AND ROCKING BUILDING FRAMES EQUIPPED WITH AN ENERGY DISSIPATION SYSTEM
Özen, Hazal; Dicleli, Murat; Department of Engineering Sciences (2023-3-06)
In this study, the effect of columns with a rocking-base isolation system on enhancing the seismic performance of a reinforced concrete building is investigated. A compara- tive study comprising of comparisons of fixed-based and rocking-based systems with post-tensioning strands and free column ends is conducted. For analysis purposes, a reinforced-concrete building with shear walls was designed, modeled, and analyzed in ETABS software. Nonlinear boundary time history analysis (NTHA) was conducted by exposi...
Dynamic modeling of structural joints
Tol, Şerife; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2012)
Complex systems composed of many substructures include various structural joints connecting the substructures together. These mechanical connections play a significant role in predicting the dynamic characteristics of the assembled systems accurately. Therefore, equivalent dynamic models of joints that consist of stiffness and damping elements should be developed and the joint parameters should be determined for an accurate vibration analysis. Since it is difficult to estimate joint parameters accurately by...
