RISA Study on Macro and Micro Characteristics and Correlation of Soil under Cyclic Freeze–Thaws
Publisher: ASCE
Abstract: When soil is subjected to freeze–thaw cycles, its macro morphology and overall strength experience certain changes that often are caused by microscopic modifications of its internal structure in geological hazards. To ...
Influences of Pipelay Parameters on Dynamic Behavior of Deepwater J-Lay System
Publisher: ASCE
Abstract: J-lay is currently the most appropriate technique for pipeline installations in deep and ultradeep waters. Pipelay parameters can significantly influence the dynamic behavior of deepwater J-lay systems. This study proposed ...
Experimental and Numerical Investigations on the Mechanical Behavior of Basalt in the Dam Foundation of the Baihetan Hydropower Station
Publisher: ASCE
Abstract: The mechanical behavior of basalt is critical to the stability and safety of large structures erected on basalt. In this paper, a series of tests (hydrostatic compression test, triaxial compression tests, and triaxial ...
Experimental Investigation and Numerical Modeling of Short-Term Mechanical and Creep Properties of Cement Mortar
Publisher: American Society of Civil Engineers
Abstract: This study conducts several laboratory tests (triaxial compression, cycle loading, and cycle loading creep tests) to explore the degradation mechanism of mechanical properties of cement mortar. The results revealed that ...
Characterization of Steel Wire– and Carbon/Glass Hybrid Fiber–Reinforced Polymer Bars in Compression
Publisher: ASCE
Abstract: This paper reports on the compressive properties of a new steel wire– and carbon/glass hybrid fiber–reinforced polymer (S-CG HFRP) bar. The influence of the carbon and glass fiber volume proportion (Vc/Vg), steel wire ...
Study of Erosion Behavior of Shale-Gas Gathering Pipeline Elbow Based on Fluid–Solid Coupling
Publisher: American Society of Civil Engineers
Abstract: The erosion of elbows in shale gas-gathering pipelines is influenced by both internal tensile stress and solid particle erosion. However, scholarly attention to the occurrence of elbow erosion in such pipelines under stress ...
A Computer-Aided Design Tool in Java for Planar Gripper Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We describe an Internet-based CAD tool that automatically designs gripper jaws that will rotate a given rigid convex polygonal part from a selected stable resting orientation to a desired final ...
Modeling Ice-Cover Melting Using a Variable Heat Transfer Coefficient
Publisher: American Society of Civil Engineers
Abstract: In cold regions, rivers may be partially or completely ice covered during a good part of the year. Under these conditions, heat transfer between the river flow and the atmosphere occurs simultaneously at the ice-air and ...
Shear Strength of RC Beams with Steel Stirrups
Publisher: American Society of Civil Engineers
Abstract: Because of the complexity of the shear failure mechanism, most current design codes and guidelines are based on highly empirical approaches and consequently should only be used within the bounds of testing regimes from ...
