RISNumerical Simulation on Thermomechanical Coupling Behavior of Early-Age Concrete in the Large-Scale Steel–Concrete Connecting Segment of a Hybrid-Girder Cable-Stayed Bridge
Publisher: ASCE
Abstract: Large-scale connecting segments can provide reasonable load transition in hybrid girders, and have been broadly used in long-span cable-stayed bridges. However, the large volume of concrete in connecting segments bears a ...
Fabrication of Anode-Supported Tubular Solid Oxide Fuel Cells by Slip Casting in Combination With Dip Coating Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dense and microcrack free yttria-stabilized zirconia (YSZ) was deposited onto porous NiO-YSZ anode tubes by dip coating without any vacuum assistance. The anode tubes were prepared by slip ...
Statistical Investigation on the Temperature Actions of CFST Truss Based on Long-Term Measurement
Publisher: ASCE
Abstract: Concrete-filled steel tube (CFST) trusses are the most common elements used in long-span CFST bridges; however, the temperature actions have not been systematically investigated. This paper presents a long-term temperature ...
Analysis of Structural Types and Mechanical Performance of Steel–Concrete Connections without Cells
Publisher: American Society of Civil Engineers
Abstract: Steel–concrete connections, as key components of hybrid bridges, present a complex structural type and mechanical behavior. On the basis of the steel–concrete connections in the Lichuan Bridge, a numerical analysis was ...
Measuring and Understanding Public Perception of Preference for Ordinary Landscape in the Chinese Context: Case Study from Wuhan
Publisher: American Society of Civil Engineers
Abstract: The change in public landscape cognition is of crucial significance in achieving sustainable landscape management, but it has not drawn enough attention in China. Landscape cognition was recognized as a cognitive process ...
Measurement and Simulation of Temperature Field of Concrete Box Girder in Northwest Severely Cold Area
Publisher: American Society of Civil Engineers
Abstract: This study evaluated the characteristics of temperature field distribution of the concrete box girder based on the middle bridge of Xiaosha River, and the effects of temperature in severely cold area were determined through ...
Effect of Phosphate Slag on the Properties of Silicate Cement Mortars
Publisher: American Society of Civil Engineers
Abstract: In this paper, solid waste phosphate slag is introduced into cement to use its phosphates to retard the setting time of cement, which is helpful for improving the mechanical properties of cement while saving energy and ...
Prediction Formula for Temperature Gradient of Concrete-Filled Steel Tubular Member with an Arbitrary Inclination
Publisher: ASCE
Abstract: Concrete-filled steel tubes (CFSTs) have been used extensively as main members with different inclinations in bridge structures; however, investigations on the influence of member inclination on temperature gradient are ...
Aerodynamic Stability Analysis of Geometrically Nonlinear Orthotropic Membrane Structure with Hyperbolic Paraboloid
Publisher: American Society of Civil Engineers
Abstract: This paper studies the aerodynamic stability of a tensioned, geometrically nonlinear orthotropic membrane structure with hyperbolic paraboloid. The aerodynamic force acting on the membrane surface is determined by the ...
