Composite action between a reinforced concrete deck and steel girders is usually achieved by making use of welded headed shear studs. The mechanics of shear studs embedded in mature concrete has been investigated extensively in the past. Current literature, however, lacks experimental evidence of steel-concrete interface behavior at early concrete ages. This information is useful in understanding the behavior of bridges during construction. Current testing methods are not suitable for determining the response of shear studs embedded in early-age concrete. In order to avoid this limitation, a new pushout test setup has been developed. A total of 24 pushout tests were performed at concrete ages ranging from 4 h to 28 days. Test results were used to develop load-slip curves and strength expressions. Furthermore, the variation of concrete properties with time and the applicability of the existing code equations for predicting early-age concrete stiffness were examined. Test results revealed that shear transfer is achieved at very early concrete ages and rate of stiffness gain of concrete is greater than that of strength.

Strengthening of reinforced concrete frames with engineered cementitious composite panels Ayatar, Mehmet Engin; Canbay, Erdem; Binici, Barış (Thomas Telford Ltd., 2020-04-01) Infill walls in reinforced concrete frames are susceptible to failure owing to their brittle nature. Their interaction with boundary columns during earthquakes may also cause shear damage in the columns. It is crucial to employ effective seismic strengthening strategies in order to mitigate the seismic risk induced by the infill walls. In this study, a new strengthening technique, conducted by bonding engineered cementitious composite (ECC) precast panels onto infill walls, was investigated. Three reinforce...
Evaluation of the Predictive Models for Stiffness, Strength, and Deformation Capacity of RC Frames with Masonry Infill Walls Turgay, Tahsin; Durmus, Meril Cigdem; Binici, Barış; Ozcebe, Guney (American Society of Civil Engineers (ASCE), 2014-10-01) Buildings with masonry infill walls (MIWs) in reinforced concrete (RC) frames are commonly used all around the world. It is well known that infill walls may affect the strength, stiffness, and displacement ductility of the structural system. Different approaches have been adopted in different codes and guidelines to consider the stiffness and strength contribution of MIWs on RC frame behavior. This study compares the ability of the existing guidelines to estimate stiffness, strength, and deformability of RC...
Lifetime performance analysis of existing steel girder bridge superstructures Akgül, Ferhat (American Society of Civil Engineers (ASCE), 2004-12-01) A general method for lifetime performance analysis of existing steel girder bridges is presented. Only the superstructure components are considered. The formulation is established by identifying four distinct categories: limit state equations, random variables, deterministic parameters, and constant coefficients. The limit state equations are derived by strictly adhering to the load and capacity formulas and requirements set forth in AASHTO specifications. Generality is pursued by establishing parametric li...
Overlapping Lattice Modeling for concrete fracture simulations using sequentially linear analysis Aydın, Beyazıt Bestami; Tuncay, Kağan; Binici, Barış (Wiley, 2018-04-01) Modeling concrete fracture is important in order to uncover accurately the sources of distress which lead to the damage or failure of structures. Many different numerical approaches have been used in the past employing either a smeared or a discrete cracking approach. Those models have difficulty in capturing the local nature of cracking, as well as the direction of crack propagation. Lattice modeling and peridynamics (PD) are some of the more recent nonlocal fracture simulation tools which possess advantag...
Analysis of the effects of vertical pre-release cracks on prestressed concrete bridge girders Baran, Eray; French, Catherine; Wyffels, Tina (Precast/Prestressed Concrete Institute, 2004-11-01) Vertical cracks, termed "pre-release cracks," beginning at the top flange and propagating downward into the section depth have been observed to develop during the production of long-span prestressed concrete bridge girders. The cracking which is attributed to the restrained shrinkage the concrete and thermal effects during the curing period prior to release of the prestressing strands, tends to be more critical for long-span girders with deep sections and large amounts of prestressing strands. Studies were ...
