RISLarge Rupture Strain FRP-Confined Concrete Columns of Different Sizes: Experiments and Stress–Strain Models
Publisher: ASCE
Abstract: Extensive experimental and theoretical studies of large rupture strain (LRS) fiber-reinforced polymer (FRP)-confined concrete columns have been conducted based on small-scale columns, mostly with a diameter of 150 mm. This ...
Discrete Time Sliding Mode Switching Control Scheme With Disturbance Observer and Its Application to Superheated Steam Temperature Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we have addressed a slidingmode switching control scheme with disturbance observer for a class of singleinput singleoutput (SISO) discrete switched nonlinear systems which suffer from uncertain parameters. ...
Nonlinear Analysis of a New Extended Lattice Model With Consideration of Multi Anticipation and Driver Reaction Delays
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new extended lattice model of traffic flow is presented by taking into account both multianticipative behavior and the reactiontime delay of drivers. The linear stability theory and the nonlinear analysis method are ...
Cyclic Compressive Behavior of Concrete Confined with Large Rupture Strain FRP Composites
Publisher: American Society of Civil Engineers
Abstract: Fiber-reinforced polymer (FRP) composites with a large rupture strain (LRS) (i.e., having an ultimate tensile strain larger than 5%) are promising jacketing materials for the seismic retrofit of reinforced concrete (RC) ...
Behavior and Modeling of Concrete Confined with FRP Composites of Large Deformability

Abstract: This paper presents the results of an experimental study on the behavior of concrete confined by fiber reinforced polymer (FRP) jackets with a large rupture strain (LRS). The FRP composites considered herein are formed by ...
Effect of Welding Residual Stress on the Buckling Behavior of Storage Tanks Subjected to Harmonic Settlement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of welding residual stress on the buckling behavior of storage tanks subjected to the harmonic settlement was simulated using the shell-to-solid coupling method. In the numerical model of tanks coupled with the ...
Monotonic Stress–Strain Behavior of Steel Rebars Embedded in FRP-Confined Concrete Including Buckling
Publisher: American Society of Civil Engineers
Abstract: Fiber-reinforced polymer (FRP) confining jackets offer an attractive solution for the seismic retrofit of RC columns. For the accurate prediction of strength and ductility of FRP-confined RC columns, it is necessary to ...
Neural Network Direct Adaptive Control Strategy for a Class of Switched Nonlinear Systems
