RISInterplay of Science and Stakeholder Values in Neuse River Total Maximum Daily Load Process
Publisher: American Society of Civil Engineers
Abstract: Successful engagement of stakeholders and scientists is essential when regulatory agencies want public input to environmental policy decisions that are technically complex. Standards of good practice for public involvement ...
Creating a Universal Depth-to-Load Conversion Technique for the Conterminous United States Using Random Forests
Publisher: ASCE
Abstract: As part of an ongoing effort to update the ground snow load maps in the US, this paper presents an investigation into snow densities for the purpose of predicting ground snow loads for structural engineering design with ...
Cost Model of Industrial Fluidized Bed Boilers
Publisher: American Society of Civil Engineers
Abstract: Fluidized bed combustion in industrial applications offers many advantages from the resource utilization and the air quality points of view. A cash flow model is developed to predict the economic consequences of an investment ...
Framework for Mitigating Human Bias in Selection of Explanatory Variables for Bridge Deterioration Modeling
Publisher: American Society of Civil Engineers
Structural Performance of Precast/Prestressed Bridge Double-Tee Girders Made of High-Strength Concrete, Welded Wire Reinforcement, and 18-mm-Diameter Strands
Publisher: American Society of Civil Engineers
Abstract: This paper presents the development of high-strength precast prestressed double-Tee girders for bridge construction. These girders use high-strength concrete (103 MPa), Grade 550 welded wire reinforcement, and 18-mm-diameter ...
Retrieval of Raindrop Size Distributions Using Two Doppler Wind Profilers: Model Sensitivity Testing
Publisher: American Meteorological Society
Abstract: The behavior of precipitation is of great importance in obtaining a better understanding of heat transport estimates and global processes in the atmosphere. This paper discusses improvements in an earlier raindrop size ...
Predicting Utah Ground Snow Loads with PRISM
Publisher: American Society of Civil Engineers
Abstract: Despite their importance in building design, ground snow load requirements remain largely undefined for the western United States. This paper proposes an adaptation of the Parameter-Elevation Relationships on Independent ...
Stochastic Modeling of Bridge Deterioration Using Classification Tree and Logistic Regression
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new method to develop stochastic deterioration models using a combination of methods including Markov chains, logistic regression, and classification trees. It is computationally more efficient to use ...
Fatigue Crack Detection Using Unmanned Aerial Systems in Fracture Critical Inspection of Steel Bridges
Publisher: American Society of Civil Engineers
Abstract: Many state agencies are investigating the use of unmanned aerial systems (UASs) for bridge inspections. Some agencies are receiving pressure from consultants and their own administrations to implement UAS inspections with ...
Live-Load Testing and Long-Term Monitoring of the Varina-Enon Bridge: Investigating Thermal Distress
Publisher: American Society of Civil Engineers
Abstract: During detailed visual inspections, inspectors on the Varina-Enon Bridge noticed a significant flexural crack opening, visually estimated at 1.5 mm under traffic, on the last span of the approach structure among other ...
