Structural 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
Stiffness and Deflection of Steel–Concrete Composite Beams under Negative Bending
Publisher: American Society of Civil Engineers
Abstract: Compared with simply supported beams, continuous steel–concrete composite beams have many advantages such as higher span/depth ratio, less deflection, and higher fundamental frequency of vibration due to its higher stiffness. ...
Research on Cable Anchorage Systems for Self-Anchored Suspension Bridges with Steel Box Girders
Publisher: American Society of Civil Engineers
Abstract: A new type of steel-concrete composite cable anchorage system is conceived and investigated preliminarily for self-anchored suspension bridges with steel box girders to optimize the mechanical behavior of the conventional ...
Longitudinal Stiffness of Multispan Suspension Bridges
Publisher: American Society of Civil Engineers
Abstract: The longitudinal stiffness of multispan suspension bridges plays an important role in load-resisting systems. In this paper, a model defined as the kinematic multispring (KMS) model is proposed for simulating the longitudinal ...
Closure to “Long-Term Behavior of Composite Beams under Positive and Negative Bending. I: Experimental Study” by Jiansheng Fan, Jianguo Nie, Quanwang Li, and Hao Wang
Publisher: American Society of Civil Engineers
Experimental Study on the Seismic Performance of 3D Joints between Concrete-Filled Square Steel Tubular Columns and Composite Beams
Publisher: American Society of Civil Engineers
Abstract: Six three-dimensional (3D) joints between concrete-filled square steel tubular columns and composite steel-concrete beams were tested under bidirectional reversal loads. The primary purpose of this experiment was to ...
Long-Term Behavior of Composite Beams under Positive and Negative Bending. I: Experimental Study
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental program designed to examine the long-term behavior of composite steel-concrete beams under sustained loads. The test program consisted of two simply supported beams under positive bending ...
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 ...
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 ...
