RISA Time-Reversal Defect-Identifying Method for Guided Wave Inspection in Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The temporal-spatial focusing effect of the time-reversal method on the guided wave inspection in pipes was investigated theoretically in the current research with a transfer function. The amplitude ...
Optimal Sizing of an Air Vessel in a Long-Distance Water-Supply Pumping System Using the SQP Method
Publisher: American Society of Civil Engineers
Abstract: By optimizing the sizing of air vessels, not only is the damage from water hammer prevented, but also the cost of water hammer protection systems is minimized. This paper presents a numerical simulation of an air vessel ...
Dielectric Modeling of Asphalt Mixtures and Relationship with Density
Publisher: American Society of Civil Engineers
Abstract: The paper is aimed at investigating the dielectric response of the dense-graded hot-mix asphalt mixture (HMA) using an open-ended coaxial probe technique over a wide frequency range. The effects of asphalt content, air ...
Designing and Analyzing the Hazardous Material Transportation Network of Urban Cities
Publisher: American Society of Civil Engineers
Abstract: To research and study the topology of a hazardous material transportation (HMT) network, we analyze the properties of path choice models and their problems and build an appropriate normative and standard frame. We present ...
Product Multibody Dynamics Analysis for Low-Carbon Footprint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increasingly serious global climate problem, the low-carbon design of products has gradually become an important direction of sustainable manufacturing. The optimization design of product structure is one of the ...
Substructure Modeling and Loading-Control Techniques for the Test of a Full-Scale Spatial RC Frame with Buckling-Restrained Braces Subjected to Bidirectional Loading
Publisher: ASCE
Abstract: To investigate the performance of reinforced-concrete frames with buckling restrained braces (RCF-BRB) subjected to bidirectional earthquakes, a full-scale two-story RCF-BRB was tested using substructured pseudodynamic ...
Empirical Analysis of Commuters’ Nonwork Stop-Making Behavior in Beijing, China
Publisher: American Society of Civil Engineers
Abstract: This paper presents a mathematical model to determine both a worker’s decision to participate in a nonwork activity and the decision about whether to include it in the basic home–work–home commute. By using household travel ...
Method for Resolving Contact Indeterminacy in Three-Dimensional Discontinuous Deformation Analysis
Publisher: American Society of Civil Engineers
Abstract: Because of the nonlinearity nature of contacts, real contact information in discontinuous computation is unknown before analysis. In standard three-dimensional (3D) discontinuous deformation analysis (3D DDA), the ...
Experimental Performance of a Full-Scale Spatial RC Frame with Buckling-Restrained Braces Subjected to Bidirectional Loading
Publisher: ASCE
Abstract: To investigate the performance of a RC frame with buckling-restrained braces (RCF-BRB) subjected to bidirectional earthquakes, a full-scale two-story RCF-BRB was tested using substructural pseudodynamic, quasi-static, and ...
