Analytical studies to evaluate the seismic response of reinforced concrete moment resisting frame structures, with and without joint deformations, demonstrated that the predicted inelastic behavior was not accurate when the joint region was assumed to be rigid. One of the main purposes of the research program was to develop a joint model that accounts for deterioration of shear strength and stiffness within the connection region and concentrated rotation due to rebar slip. The experimental data on joint distortion was used to develop and verify an analytical model that includes shear deformation and concentrated joint rotation components. The developed joint deformation model was then used in the nonlinear analysis of reinforced concrete buildings that provide different frame configurations and inelastic responses. The structures were subjected to inelastic dynamic time history analyses, using a variety of earthquake records that represent different levels of seismic risk. It was observed that if a deformable joint model was not included in the structural model, story drifts were underestimated significantly. Results of the nonlinear analyses for a selected building and brief information on the member modeling, including the joint model developed for this research program, are presented in this paper.

SEISMIC PERFORMANCE OF SINGLE-SPAN SIMPLY SUPPORTED AND CONTINUOUS SLAB-ON-GIRDER STEEL HIGHWAY BRIDGES Dicleli, Murat (1995-10-01) Seismic response of single-span simply supported and continuous slab-on-girder steel bridges is studied. Linear elastic and nonlinear inelastic analyses are conducted for various ground-acceleration inputs. Bearings with higher stiffnesses that are closer to the edge of the deck are found to attract larger forces than other bearings, whereas bearings with small stiffness attract almost equal forces regardless of the width of the brid e. Assuming that the anchors of otherwise stable bearings are severed, sli...
Seismic testing of a scaled roller-compacted-concrete gravity dam Gharibdoust, Ali; Binici, Barış; Department of Civil Engineering (2016) Within the last half-century, seismic response analysis of concrete gravity dams has been extensively studied. Studies reveal that two types of failure modes prevail in the form of dam body cracking or base slide. The literature lacks the conditions that clearly differentiate the two failure types. In this context a state of the art single degree of freedom pseudo-dynamic testing was developed to assess the gravity dam response on smooth foundation interface. Three different hazard levels of earthquake name...
Consistent matrices for steel framed structures with semi-rigid connections accounting for shear deformation and rotary inertia effects ÖZEL, HALİL FIRAT; Sarıtaş, Afşin; Tasbahji, Tayseer (2017-04-15) Estimation of vibration characteristics and thus the seismic loads acted on steel framed structures are influenced by the presence of semi-rigid connections and accurate modeling of shear deformations and rotary inertia effects. This paper presents a finite element model that takes into account all these effects in order to calculate consistent stiffness and mass matrices. The formulation of the element utilizes three fields Hu-Washizu-Barr principle, where the need for displacement shape function approxima...
Ground motion prediction equations based on simulated ground motions Gür, Kader; Askan Gündoğan, Ayşegül; Kale, Özkan; Department of Earthquake Studies (2018) Ground Motion Prediction Equations (GMPEs) are one of the key elements in seismic hazard assessment to estimate ground motion intensity measures by basically taking into account source, path and site effects. Most of the existing predictive models are derived from databases compiled from real (or observed) ground motion data. However, in data-poor regions, a novel practice to develop new GMPEs is to use simulated or hybrid ground motion datasets for performing reliable seismic hazard analysis. Simulations o...
Seismic behavior of autoclaved aerated concrete reinforced vertical panel buildings Gökmen, Furkan; Binici, Barış; Department of Civil Engineering (2017) In this study, the seismic behavior of Autoclaved Aerated Concrete (AAC) reinforced panel walls and buildings was investigated. The structural members were investigated under cyclic lateral loading and axial load and the results were compared with the previous tests. The main objective of this study was to provide recommendations for nonlinear analysis of the reinforced AAC panel walls and buildings. OpenSees plat-form was chosen as the computational platform. The walls were modeled with fiber sections. The...
