RISInvestigation of Bridge Expansion Joint Failure Using Field Strain Measurement
Publisher: American Society of Civil Engineers
Abstract: This study was initiated after the sliding plate expansion joints of Millard E. Tydings Memorial Bridge, a long-span truss bridge, failed prematurely just a few months after their initial installation. The study included ...
Three-Dimensional Simulations of Plate Anchor Pullout in Granular Materials
Publisher: American Society of Civil Engineers
Abstract: Plate anchors are embedded into the ocean floor to provide holding capacity for offshore structures. Anchor holding capacity is a function of both the anchor and soil properties. Although plate anchors have been widely ...
Thermal Conductivity of Quartz Sands by Thermo-Time Domain Reflectometry Probe and Model Prediction
Publisher: American Society of Civil Engineers
Abstract: The heat transfer process in soil depends on its thermal conductivity property and is affected by soil compositional and environmental factors, such as soil gradation, mineralogy components, compaction moisture content, ...
Flow-Complexity Analysis of the Upper Reaches of the Yangtze River, China
Publisher: American Society of Civil Engineers
Abstract: Flow complexity, which means the degree of uncertainty or the rate of information production of a flow series, is analyzed for the upper reaches of the Yangtze River. Sample entropy (SampEn) is applied to measure flow ...
Fatigue-Life Prediction of Corroded Steel Bar Based on Fractal Theory
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental study that sought to characterize the effect of corrosion and fatigue load on the behavior of reinforcing steel bars. The surface profiles of corroded steel bars and the relationship ...
Experimental Study on Load-Transfer Mechanism of Rockbolts Using Fiber Optic and Strain Gauge Monitoring
Publisher: American Society of Civil Engineers
Abstract: As a cost-effective rock-supporting method, rockbolts have been widely used in geotechnical and mining engineering. Better understanding the load-transfer mechanism of rockbolts is of great importance for improving the ...
Including Class F Fly Ash to Improve the Geopolymerization Effects and the Compressive Strength of Mine Tailings–Based Geopolymer
Publisher: ASCE
Abstract: Mine tailings (MTs) that are rich in aluminosilicates can be reused to create geopolymer via alkaline activation as an alternative to portland cement concrete for construction and building applications. However, pure MTs ...
Production Characteristics and Importance of Uncertain Parameters of Water Huff-n-Puff for Volume Stimulation Horizontal Wells in Tight Oil Reservoirs
Publisher: ASCE
Abstract: Water huff-n-puff is considered to be an available method to exploit unconventional oil reservoirs, which can significantly promote the reservoir pressure and facilitate water–oil exchange under the imbibition effect. To ...
Study of Hydrological Simulation on the Basis of Digitized Basin
Publisher: American Society of Civil Engineers
Abstract: On the basis of geographic information systems, indices of basin terrains and some other characteristics were extracted. Drainage networks were created by different mesh sizes of digital elevation model (DEM) in the basin ...
Frequency Identification of Practical Bridges through Higher-Order Spectrum
Publisher: American Society of Civil Engineers
Abstract: Identifying the frequencies of practical bridges can help in understanding the bridge dynamic property. However, the vibration amplitude excited by wind load and traffic load is too small, resulting in a small signal noise ...
