RISPractical Formula for Cable Tension Estimation by Vibration Method
Publisher: American Society of Civil Engineers
Abstract: The tension force of cables must be measured accurately during construction and maintenance stages for cable-supported bridge systems. On the basis of the transverse vibration equation of a cable and by using a curve-fitting ...
Behavior of Tendons with Multiple CFRP Rods
Publisher: American Society of Civil Engineers
Abstract: Research works related to the fiber-reinforced polymer (FRP) tendons have focused on the anchor system, but the anchor is not the only contribution to performance. Since civil structures require tendons consisting of ...
Lateral Vibration of High-Pier Bridges under Moving Vehicular Loads
Publisher: American Society of Civil Engineers
Abstract: When studying the vibration of a bridge-vehicle coupled system, most researchers focus on the vertical vibration of bridges under moving vehicular loads. In reality, the moving vehicular loads can also induce significant ...
Time-Dependent Reliability and Redundancy of Corroded Prestressed Concrete Bridges at Material, Component, and System Levels
Publisher: American Society of Civil Engineers
Abstract: Due to structural deterioration, the performance of concrete bridges degrades with time and may result in catastrophic failure events, especially for nonredundant structures. This paper develops a methodology for assessing ...
Fatigue Behavior of Stirrup Free Reactive Powder Concrete Beams Prestressed with CFRP Tendons
Publisher: ASCE
Abstract: A comprehensive study on the fatigue behavior of stirrup free reactive powder concrete (RPC) beams prestressed with carbon fiber-reinforced polymer (CFRP) tendons is presented in this paper. A total of six specimens were ...
Behavior of CFSC-Encased Shear Connectors in Steel-Concrete Joints: Push-Out Tests
Publisher: ASCE
Abstract: A concrete-filled steel cell (CFSC) is commonly used in steel-concrete joints of hybrid girders. The performance of shear connectors embedded in CFSCs has been investigated in the current study in which a series of push-out ...
Experimental Behavior of UHPC Shear Walls with Hybrid Reinforcement of CFRP and Steel Bars under Lateral Cyclic Load
Publisher: ASCE
Abstract: A new kind of structural system, ultrahigh-performance concrete (UHPC) shear walls reinforced with carbon fiber–reinforced polymer (CFRP) and steel bars, is proposed in this study. CFRP bars were used in the web region of ...
Fatigue Behavior of UHPC Beams Prestressed with External CFRP Tendons
Publisher: ASCE
Abstract: This paper presents an experimental investigation of the fatigue behavior of ultrahigh-performance concrete (UHPC) beams prestressed with external carbon fiber-reinforced polymer (CFRP) tendons. Seven T-shaped beams were ...
Effect of Strain Rate on the Bond Performance of Carbon Fiber–Reinforced Polymer Tendons in Ultrahigh-Performance Concrete
Publisher: American Society of Civil Engineers
Abstract: This paper aims to investigate the contribution of chemical adhesion and friction to the bond stress of a smooth carbon fiber–reinforced polymer (CFRP) tendon in ultrahigh-performance concrete (UHPC) under different strain ...
Experimental Investigations on Impact Behavior of CFRP Cables under Pretension
Publisher: American Society of Civil Engineers
Abstract: Carbon fiber–reinforced polymer/plastic (CFRP) used in bridge cables may be subjected to lateral impacts caused by vehicle collisions when in service. However, to date, few studies have been conducted on the impact behavior ...
