Internal Force Changes in the Failure Process of Existing Reinforced Concrete Arch Ribs
Publisher: American Society of Civil Engineers
Abstract: Experimental results were studied in detail for an existing reinforced concrete arch rib. Based on the static and modal experimental results, its stiffness was not reduced consistently, although it demonstrated fluctuation. ...
Cracking Risks, Durability, and Life-cycle Costs for RC Bridges Subject to Carbonation-induced Corrosion
Publisher: American Society of Civil Engineers
Abstract: Based on the corrected carbonation depth prediction model, this study develops a time-dependent structural reliability model to predict the probability of serviceability failure subject to carbonation-induced corrosion, ...
Research on Fatigue Reliability of Cables of Partially Cable-stayed Bridge under Vehicle Load
Publisher: American Society of Civil Engineers
Abstract: The tolerated stress of static strength has not been provided in domestic code for design of highway cable-stayed bridges. In order to quantify the fatigue reliability of stay cable on partially cable-stayed bridge under ...
Effects 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 ...
Strengthening a 20-Year-Old Post-Tensioned Concrete Box Beam with Double-Layer Prestressed Steel Wire Ropes
Publisher: American Society of Civil Engineers
Abstract: Overloading, corrosion, and material aging deteriorate the structural performance of prestressed concrete (PC) bridges. Strengthening techniques are needed to improve the serviceability and extend the life of these ...
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 ...
