RISDetermination of Dynamic Amplification Factors Using Site-Specific B-WIM Data
Publisher: American Society of Civil Engineers
Abstract: The dynamic amplification factor (DAF) is a significant parameter for new bridge design and characterization of existing bridges. The AASHTO code provides a predicted value based on an assumed structural model, but not one ...
Multitransformable Leaf Out Origami With Bistable Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We study the kinematics of leafout origami and explore its potential usage as multitransformable structures without the necessity of deforming the origami's facets or modifying its crease patterns. Specifically, by changing ...
Indoor Air Quality Assessment of Metro Stations Based on the Optimal Combination Weight and Improved Fuzzy Comprehensive Evaluation
Publisher: American Society of Civil Engineers
Abstract: Aair quality issues and respiratory diseases have become issues of particular concern since the outbreak of the COVID-19 pandemic. The indoor air quality of crowded places such as underground metro stations has received ...
Operational Strategies and Governance Policies for the Water Diversion–Conservation Coupled Supply Chain: A Dual Perspective of Broadening Source and Reducing Expenditure
Publisher: American Society of Civil Engineers
Abstract: AbstractSustainable operations and governance are significant issues that need to be solved
urgently in the operations management of interbasin water transfer (IBWT) projects.
This paper constructs a water-diversion–conservation ...
Bridge Weigh-in-Motion Algorithms Based on the Field Calibrated Simulation Model
Publisher: American Society of Civil Engineers
Abstract: Most of the commercially available bridge weigh-in-motion (B-WIM) systems are based on an algorithm developed by Moses. The performance of this method was generally acceptable for estimating gross vehicle weight (GVW) but ...
Improved FORM and SORM Based on Improved Modified Symmetric Rank 1 Algorithm and Adaptive Kriging Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The first-order reliability method (FORM) is simple and efficient for solving structural reliability problems but may have large errors and converge slowly or even result in divergence when dealing with strongly nonlinear ...
Effect of Nonstationarity on Shear Properties of Rock Joints and a New Peak Shear Strength Criterion
Publisher: ASCE
Abstract: In rock masses, there might be structural nonstationarity in the joint morphology that influences the shear behavior of rock joints. However, research into this effect is seldom reported. In this study, shear tests on ...
