Safeguarding Steel
U.S. bridges are caught in the money squeeze. Painting has become a luxury few public agencies can afford and complying with EPA regulations has escalated costs even more. The paint/coatings...
Design Cable-stayed Bridge for Cost Effectiveness and Safety
Innovative design approach is needed to enhance the prestigious status enjoyed by cable-stayed bridges. The present paper aims at such a goal of cost effectiveness and safety by providing...
Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...
Human Habitat Design for the Space Exploration Initiative
The design of spacecraft to accomodate humans for long lengths of time e.g. conjunction-class human missions to Mars, must carefully consider both the physical and mental health of the...
Space Habitat Contaminant Growth Models?Part II
This paper reports on the continuation of work being done at NASA's Center for Space Environmental Health (CSEH) at the University of Colorado at Boulder on contaminant growth modelling...
Robotics in SEI Terrestrial Launch Site Operations
This paper addresses work performed at Rockwell International's Space Systems Division, Downey, California. Future Space Exploration Initiative (SEI) missions will require terrestrial...
Lunar Base Pressure, O2 Fraction, and ExtraHabitat Activity Suit Design
A major dilemma exists in determining optimum habitat and ExtraHabitat Activity (EHA) suit pressures for future space missions, balancing human safety requirements and the case of EHA...
Medical Care on the Moon
Eventually, people will return to the Moon to stay for prolonged periods of time. When they do, they will be exposed to a wide range of threats to their health including, decompression...
The Isolated Signalized Intersection as a Mitigation on a High-Speed Highway
A concentrated 'leap-frog' type development is commonly proposed as it offers the opportunity to organize an extensive living-recreation orientated site with low to modest land costs....
The Last Freeway
Ever since what's now known as the Pasadena Freeway was completed in 1940, Los Angeles has been synonymous with the freeway�first with the ease and speed of transport it represented...
Housing Chernobyl Relocatees
The April 1986 explosion of the Chernobyl Nuclear Power Plant Reactor 4 in northern Ukraine Commonwealth spread nuclear contamination assisted by southerly winds across hundreds of miles...
Effectiveness of Implemented HOV Lane System
Individual carpool lanes have proven their worth on a case by case basis. Now, in California and across the country, systems of HOV lanes are being planned for urban areas dealing with...
Responding to Public Opinion About Cumulative Long-Term Risks: Analysis and Communication of Risks from Climate Change and Hazardous Waste Sites
Public reactions to cumulative, uncertain, and long-term (CULT) risks pose particular problems to risk communicators. Low-magnitude and low-probability risks (e.g., living next to a hazardous...
Conflicts in Health and Safety Matters: Between a Rock and a Hard Place
Constraints on time and resources influence the public sector as strongly as they influence our personal lives. Experience teaches us that our desires must be tempered by hard realities....
Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...
Controlled Braking on Uneven Roads
The braking process of a passenger car may be influenced by a large number of variables relating to driver, vehicle, brake system, tire-road interaction and ambient conditions. Because...
Probabilistic Evaluation of Redundancy of Bridge Structures
Redundancy of bridge structures and methods to evaluate redundancy are reviewed in this paper. A method to measure redundancy based on the existing theories of probability as related to...
Pre-Envelope Covariance Differential Equations
The problem of predicting the safety of structural systems subjected to random loading arises in may engineering applications. In this framework the envelope process plays an important...
Structural Reliability and Proof Testing for Highway Bridges
This paper proposes a set of reliability-based proof load factors for highway bridge evaluation, to determine target proof load and load rating. The target safety index used is consistent...
Soil/Structure Seismic Investigation of Safety-Related Structures
This paper promotes an improved understanding of the type of earthquake motions felt at V.C. Summery, Perry and Krsko nuclear power plants. An analytical investigation is performed to...
