RISEffects of Stress Ratio and Banded Microstructure on Fatigue Crack Growth Behavior of HRB400 Steel Bar
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the effects of stress ratio and microstructure on the fatigue crack growth (FCG) behavior of HRB4 steel bars widely used in concrete bridges. A constant stress–controlled FCG test with different ...
Localization and Automatic Quantification of Crack Damage in Steel Structures Using Ultrasonic Guided Wave Technology
Publisher: American Society of Civil Engineers
Abstract: AbstractUltrasonic guided wave (UGW) technology is an effective method for intelligent monitoring
of crack damage in thin-walled plate structures. In this paper, a finite-element (FE)
model of UGW propagation in Q345 steel ...
Shear Capacity of Reinforced Concrete Beam with Diagonal Reinforcement Based on Modified Compression Field Theory
Publisher: American Society of Civil Engineers
Abstract: For the compression—shear failure of a reinforced concrete bridge beam with diagonal reinforcement, the calculation of ultimate shear capacity is proposed based on the modified compression field theory (MCFT). Shear force ...
