RISExperimental Study on the Shear Behavior of UHPC-Strengthened Concrete T-Beams
Publisher: ASCE
Abstract: Ultrahigh-performance concrete (UHPC) strengthening is an efficient technique to improve the capacity of shear-deficient members. However, the applicability of UHPC strengthening on a T-beam has been scarcely investigated, ...
Analytical Model for Calculating Shear Capacity of NSC Beams Strengthened by UHPC Lateral Layers
Publisher: ASCE
Abstract: The utilization of ultrahigh-performance concrete (UHPC) as lateral or U-shaped thin layers to strengthen the shear-deficient normal-strength concrete (NSC) beams is an effective and promising way to increase their stiffness ...
Shear Strength of Dry Joints in Precast UHPC Segmental Bridges: Experimental and Theoretical Research
Publisher: American Society of Civil Engineers
Abstract: Precast segmental bridges made of ultrahigh-performance concrete (UHPC) have gained wide research attention and application. The shear transfer of dry joints between UHPC segments is one of the major concerns due to the ...
Direct Shear Strength Prediction for Precast Concrete Joints Using the Machine Learning Method
Publisher: ASCE
Abstract: Precast segmental concrete beams (PSCBs) are being increasingly applied in bridges worldwide benefitting from the advantages of accelerated bridge construction. It is of importance to accurately predict the direct shear ...
Cost-Effective UHPC for Accelerated Bridge Construction: Material Properties, Structural Elements, and Structural Applications
Publisher: ASCE
Abstract: Accelerated bridge construction (ABC) is becoming progressively popular in China due to its advantages in sustainable development. However, some challenges still prevent it from being further widespread, especially in some ...
