RISCreating 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 ...
Framework for Mitigating Human Bias in Selection of Explanatory Variables for Bridge Deterioration Modeling
Publisher: American Society of Civil Engineers
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 ...
Performance Evaluation of a New Precast Concrete Bridge Deck System
Publisher: American Society of Civil Engineers
Abstract: Precast concrete (PC) deck systems have several advantages over cast-in-place (CIP) concrete decks in bridge construction, such as improved quality, reduced construction duration, and less dependence on weather and site ...
Comparing Design Ground Snow Load Prediction in Utah and Idaho
Publisher: American Society of Civil Engineers
Abstract: Snow loads in the western United States are largely undefined due to complex geography and climates, leaving the individual states to publish detailed studies for their region, usually through the local Structural Engineers ...
Performance Evaluation of a New Precast Concrete Bridge Deck System
Publisher: American Society of Civil Engineers
Abstract: Precast concrete (PC) deck systems have several advantages over cast-in-place (CIP) concrete decks in bridge construction, such as improved quality, reduced construction duration, and less dependence on weather and site ...
Investigating the Mechanical Properties and Fracture Behavior of Welded-Wire Reinforcement
Publisher: ASCE
Abstract: Welded-wire reinforcement (WWR) is widely used as the main reinforcement in bridge decks and vertical shear reinforcement in concrete bridge girders. Previous studies on concrete members reinforced with WWR have indicated ...
Iterative and Simplified Sandwich Beam Theory for Partially Composite Concrete Sandwich Wall Panels
Publisher: ASCE
Abstract: This paper presents an iterative sandwich beam theory (ISBT) and a simplified version suitable for the design termed simplified sandwich beam theory (SSBT) used to predict the elastic mechanics of partially composite ...
Comparing Testing Methods of Partially Composite Sandwich Wall Panel Glass Fiber–Reinforced Polymer Connectors
Publisher: ASCE
Abstract: Precast concrete insulated sandwich wall panels have been commonly used as exterior load bearing or cladding wall panels on building structures. These panels are usually designed as composite, partially composite, or ...
