RISNonlinear Finite-Element Analysis of Posttensioned Concrete Bridge Girders
Publisher: American Society of Civil Engineers
Abstract: Posttensioning is an effective method for the construction of different types of bridge girders such as those used in segmentally erected bridges. Available nonlinear analysis programs for bridge girders under severe loading ...
Nonlinear Analysis of Reinforced Concrete Beam–Columns with Bond-Slip
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new model for nonlinear analysis of reinforced concrete beam–columns with bond–slip. The model is derived from a two-field mixed formulation with independent approximation of forces and displacements. ...
Mixed Formulation of Inelastic Composite Shear Beam Element
Publisher: ASCE
Abstract: This study presents a new beam element formulation following a Hellinger-Reissner functional for composite members considering coupling between bond-slip and shear deformations. A robust state determination along with new ...
Inelastic Displacement Ratios of Degrading Systems
Publisher: American Society of Civil Engineers
Abstract: Seismic code provisions in several countries have recently adopted the new concept of performance-based design. New analysis procedures have been developed to estimate seismic demands for performance evaluation. Most of ...

Mixed Formulation of Nonlinear Steel-Concrete Composite Beam Element
Publisher: American Society of Civil Engineers
Abstract: This paper presents an inelastic beam element for the analysis of steel-concrete girders with partial composite action under monotonic and cyclic loads. The element is derived from a two-field mixed formulation with ...
Finite-Element Model for Pretensioned Prestressed Concrete Girders
Publisher: American Society of Civil Engineers
Abstract: This paper presents a nonlinear model for pretensioned prestressed concrete girders. The model consists of three main components: a beam-column element that describes the behavior of concrete, a truss element that describes ...
Mixed Formulation of Bond-Slip Problems under Cyclic Loads
Publisher: American Society of Civil Engineers
Abstract: The stress transfer mechanism between reinforcing steel and surrounding concrete through bond and the resulting slip plays an important role in the hysteretic behavior of reinforced concrete structures. Earlier models of ...
Three-Dimensional Nonlinear Finite-Element Analysis of Prestressed Concrete Beams Strengthened in Shear with FRP Composites
Publisher: American Society of Civil Engineers
Abstract: Nonlinear finite-element (FE) analysis was carried out to investigate the structural response of prestressed concrete (PC) beams strengthened with fiber reinforced polymer (FRP) composites in shear. Development of the FE ...
Coupled Thermomechanical Damage Modeling for Structural Steel in Fire Conditions
Publisher: ASCE
Abstract: This study developed a coupled thermomechanical damage model for structural steel at elevated temperatures. The need for adequate modelling of steel deterioration behavior remains a challenging task in structural fire ...
