RISStructural Performance and Strength Prediction of Steel-to-Concrete Box Girder Deck Transition Zone of Hybrid Steel-Concrete Cable-Stayed Bridges
Publisher: American Society of Civil Engineers
Experimental Study on Longitudinal Shear Behavior of Prefabricated Steel–Concrete Composite Beams with Hidden Continuous Channels and Shear Key Connections
Publisher: American Society of Civil Engineers
Abstract: A full-depth deck panel (FDDP) system incorporating hidden continuous channels has emerged as a promising solution for accelerated composite bridge construction. However, the system has faced implementation challenges ...
Long-Term Behavior of Composite Beams under Positive and Negative Bending. II: Analytical Study
Publisher: American Society of Civil Engineers
Abstract: The creep, shrinkage, and cracking of concrete may induce time-dependent changes in the stresses, internal forces, and deflections of steel-concrete composite beams. This paper presents an analytical model to consider these ...
Parametric Study on the Structural Behavior and Failure Mechanism of Skewed Inverted-T Bent Caps
Publisher: ASCE
Abstract: In the past several decades, the inverted-T bent caps (ITBCs) have been frequently used as an innovative type of bridge superstructure worldwide. In some specimens, the bent caps have to be skewed to meet the landscaping ...
Biaxial Constitutive Models for Simulation of Low-Aspect-Ratio Reinforced Concrete Shear Walls
Publisher: ASCE
Abstract: A novel biaxial finite-element (FE) model is proposed and validated by a total of 32 reinforced concrete (RC) shear walls with aspect ratio below 1.5. First, a biaxial concrete model package, which was previously developed ...
Experimental Study on Steel Jacket–Concrete Composite Connections
Publisher: American Society of Civil Engineers
Abstract: Steel–concrete composite frame bridges have larger structural stiffness, lower cost, and faster construction speed than traditional bridges because a combination of steel–concrete composite girders, concrete piers, and ...
Modeling Techniques for Strain-Range-Dependent Hardening Behavior of Low-Yield-Point Steel Shear Panel Dampers
Publisher: American Society of Civil Engineers
Abstract: Shear panel dampers made of the low-yield-point steel exhibit significant overstrength under cyclic loading—a phenomenon that has been observed to depend not only on accumulated plastic deformations but also the loading ...
Design of Single-Level Guyed Towers Considering Interrelationship between Bracing Strength and Rigidity Requirements
Publisher: American Society of Civil Engineers
Abstract: Elastic buckling and second-order analyses are conducted to establish a more rigorous design procedure for single-level guyed towers, in which the interrelationship between the strength and rigidity requirements of the ...
Study of GFRP Steel Buckling Restraint Braces
Publisher: American Society of Civil Engineers
Abstract: Buckling-restraint braces (BRBs) are used extensively in seismic-resistant structures. They consist of a core energy dissipation and external restraining component. A novel glass fiber–reinforced polymer (GFRP) steel BRB ...
Triaxial Concrete Constitutive Model for Simulation of Composite Plate Shear Wall–Concrete Encased: THUC3
Publisher: American Society of Civil Engineers
Abstract: A new triaxial constitutive model [Tsinghua University Concrete Three-dimensional (THUC3)] of concrete was developed for high-fidelity finite-element (FE) simulation of composite plate shear wall–concrete encased (C-PSW/CE), ...
