Codified Reliability for Structures During Construction
It is generally acknowledged that the most critical stage of a structure's lifetime is that of construction, leading to failures or locking in forces and deformations that...
Development of Skewed Element for the Concrete Pavements
In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing...
What's Wrong With Superfund
In nine years of the federal government's Superfund program, $4 billion has been spent and only 38 of the 1,175 sites on the national priority list have been cleaned. There...
Seismic Instrumentation and Its Implication for High-Rise Buildings in Japan
An outline of the present state of the strong earthquake motions observation systems in Japan and an example of the obtained records of an earthquake and its simulation analysis of a high-rise...
Nonlinear Analysis for the Aseismic Strength of Highrise Steel Frame With Semi-Rigid Joints by Pseudo-Elastic Approach
This paper suggests that the direct stiffness method is still useful in dealing with the nonlinear analysis for the aseismic capacity of highrise steel frame while the Pseudo-elastic approach...
Amelioration of Stirrup and Compression Reinforcement on the Ductility of Reinforced High-Strength Concrete Beam
18 rectangular high strength concrete beams were tested to investigate their ductile behavior. The results show that it will be more advantageous, for ductility, to choose the compressive...
The Model Cleanup
Standards for hazardous waste site cleanups may be inappropriate or inadequate to protect the public health. Civil engineers responsible for remediation decisions need to know about the...
Structures for Enhanced Safety and Physical Security
This book presents the state-of-the-art in the general subject of structures for enhanced safety and physical security. The technical papers written are by engineers and researchers who...
Safety in the Industrial Robot Environment
Safety requirements differ for applications with or without a human interface. The extent of human interface with the robot must be determined. Design of the robot, guarding, access, and...
Adaptation of ANSI Standards for Communications Testing in the Connectionless Environment
American National Standards (X 3.102 and X 3.141) establish a uniform means for specifying, assessing and comparing performance of data communications systems and services from the point...
Incremental Risk Analysis in Teaching Institutions
Institutions engaged in research and teaching in the natural sciences, constitute a diffuse source of chemical emissions. As many institutions embark on ambitious building programs, communities...
Risk of Waterborne Infectious Illness Associated with Diving in the Point Loma Kelp Beds, San Diego, CA
There is considerable interest in estimating the risk of bacterial and viral illness (i.e., disease, infection) associated with scuba diving in the Point Loma kelp beds located within...
Environmental Risk Assessment at a Gas Utility
Over the past 10 years, Southern California Gas Company (SoCalGas) has developed an environmental risk management program to mitigate or eliminate the potential health risks to employees,...
Challenges Posed by Large-Scale Asbestos Abatement Projects in Occupied High-Rise Buildings
The challenges posed by a large-scale asbestos abatement project are great: providing a safe indoor environment for building tenants and property that is liability-free for the building...
The Application of Risk Assessment at Hazardous Waste Sites
This paper discusses some of the recent innovative uses of risk assessment at hazardous waste sites. Important developments in both methodology and application are as follows: quantitative...
Risk Assessment for the Multiple Threat from Dioxin Analysis
In this paper, the author focuses on the integrated method of estimating the risks and the evaluation of the risk acceptability based on a systematic classification of all risks involved...
Computerized Data Processing, Displays and Groundwater Flow Analyses of the Stringfellow Hazardous Waste Site
Several types of data, maps, and figures were obtained from various sources involved in the investigations and monitoring at the site. This information was discretized, and a computerized...
Weathering of Constituents at Land Treatment Sites
The objectives of this research were to: 1) determine the leachability of metals and organics from soils at hazardous waste land treatment sites; 2) evaluate the mobility of hazardous...
An Evaluation of Hazardous Waste Land Treatment Closure Options
The purpose of this research was to evaluate changes in the persistence and mobility of the residues remaining when hazardous waste land treatment (HWLT) sites are closed. This evaluation...
The Utilization of a Deflocculant to Decrease the Permeability of a Clay Liner
A hazardous waste landfill was completed in Oklahoma during 1988. The clay liner was constructed to fulfill the RCRA requirements for permeability of equal to or less than 1E-07 centimeters...
