A formal model of construction safety and health risk management

Creator:: Hallowell, Matthew R.
Abstract:: Despite recent efforts to improve site safety, construction still accounts for a disproportionate injury and illness rate. According to the 2007 injury and illness data released by the National Safety Council, the construction industry has a fatality and disabling injury rate that is approximately three times higher than the all-industry...

Chemical transformation of rice husk ash for sustainable, constructable, and durable binary cementitious system

Creator:: Prasittisopin, Lapyote
Abstract:: The production of cement and concrete results in the production of large amounts of CO₂ emissions which can have significant negative environmental impacts. Using supplementary cementing materials (SCMs) as a cement replacement is an effective solution to reduce these negative environmental impacts, as most SCMs are waste by-products from other...

The Art of Reducing Coastal Hazard Complexity: Coupling Physics and Probability to Understand Extremes, Variability, and Climate-dependence

Creator:: Anderson, Dylan L.
Abstract:: Coastal hazards are the result of numerous physical processes cumulatively causing water levels to flood and erode the land. The waves, storm surges, tides, and run-off contributing to elevated water levels are each the product of chaotic and random weather patterns. These stochastic weather patterns dissipate energy in Earth's climate...

Observational study of buffered bike lane design implementation of roadway bicycling in Portland, Oregon

Creator:: Rios, Elizabeth A.
Abstract:: Bicyclists are one of the highest and most vulnerable road users. This is due to the higher likelihood of being seriously injured when involved in a crash. This research seeks to understand two different behavioral interactions of an implemented facility user: the motorist (secondary user) and bicyclist (primary user). The...

Developing Performance-Based Specifications to Improve the Fatigue Life of Asphalt Pavements in Oregon

Creator:: Sreedhar, Shashwath
Abstract:: Asphalt concrete fatigue cracking is recognized as a major distress mode in the U.S. The widespread nature of this distress and the data from agency Pavement Management Systems (PMS) suggest that it is an issue with asphalt mixture design and production processes and is not a problem specific to certain...

A Comprehensive Mechanistic Study on Using Fine Lightweight Aggregate to Mitigate Alkali-silica Reaction

Creator:: Li, Chang
Abstract:: Previous research has shown that using fine lightweight aggregate (FLWA) can be a promising strategy to mitigate alkali-silica reaction (ASR) in mortar and concrete. While several possible theories were proposed by researchers, discrepancies in testing methods, materials, and supporting evidence still exist. Therefore, this study was initiated. There are two...

Networked Multi-agent Modeling of Connected Vehicles in Mixed Traffic Environment: A Decentralized Consensus Approach

Creator:: Wahid, Merih
Abstract:: Transportation systems are facing safety and operational challenges with a cost of billions of dollars annually in lost production time and wasted fuel. Infrastructure expansion, previously held as a panacea to most transportation challenges has lost its appeal due to financial, land-use and environmental constraints. Interest is surging in intelligent...
