Steel-FRP Reinforced Concrete Moment-Resisting Frames under Lateral Loads: Numerical Investigation
Publisher: ASCE
Abstract: This paper suggests using a combination of steel and fiber-reinforced polymer (FRP) reinforcements to introduce sustainable reinforced concrete moment-resisting frames (RC-MRFs) characterized by damage-controlled seismic ...
Seismic Performance of Steel Beams to Diamond-Shaped Concrete-Filled Steel Tube Column Connections: Concept and Validation
Publisher: ASCE
Abstract: The brittle behavior traditional directly welded connections of steel beams to concrete-filled steel tube columns is caused primarily by excessive out-of-plane deformation of the tube walls at the level of the beam tension ...
Validation of 3DFE Analysis of Rigid Pavement Dynamic Response to Moving Traffic and Nonlinear Temperature Gradient Effects
Publisher: American Society of Civil Engineers
Abstract: The response of dowel jointed concrete pavements to the combined effect of nonlinear thermal gradient and moving axle load is examined using three-dimensional finite-element (3DFE) modeling. The 3DFE-computed response to ...
Numerical Study on the Applicability of Design-Oriented Models of FRP-Confined Concrete for Predicting the Cyclic Response of Circular FRP-Jacketed RC Columns
Publisher: American Society of Civil Engineers
Abstract: This study examined the accuracy of 14 design-oriented stress-strain models of fiber-reinforced polymer (FRP)-confined concrete from the available literature to predict the cyclic responses of nine circular reinforced ...
Seismic Performance Assessment of Damage-Controlled FRP-Retrofitted RC Bridge Columns Using Residual Deformations
Publisher: American Society of Civil Engineers
Abstract: Despite the improved performance of fiber-reinforced plastic (FRP)-retrofitted bridges, residual deformations in the event of an earthquake are inevitable. Little consideration is currently given to these deformations when ...
Prediction Accuracy of Seismic Behavior of RC Noncircular Columns Retrofitted with FRP Sheets and the Impact of Local Concrete Compression Behavior
Publisher: American Society of Civil Engineers
Abstract: More than 40 models have been established to date to determine the axial compressive behavior of noncircular (square or rectangular) concrete sections confined with fiber-reinforced polymers (FRPs) under concentric loadings. ...
Impact of Thermal Models on the Performance of Natural Gas Pipelines
Publisher: American Society of Civil Engineers
Abstract: This study investigates the energy savings in the nonisothermal flow of natural gas during its pipeline transportation compared to the isothermal flow. Isothermal and nonisothermal models are adopted while considering the ...
Experimental and Numerical Evaluation of the Shear Behavior of Reinforced Concrete T-Beams with Hybrid Steel-FRP Stirrups
Publisher: American Society of Civil Engineers
Abstract: This study presents the shear behavior of reinforced concrete (RC) T-beams with innovative steel stirrups hybridized in the longitudinal direction with a fiber-reinforced polymer (FRP) composite. Six beams were experimentally ...
