Reinforced Concrete
Recent developments and procedures used to model reinforced concrete using finite element analysis are summarized. Special emphasis is placed on the results of a survey of papers published...
Hong Kong's Wastewater Underground
Standard Hong Kong methods for siting the new $18 million Stanley Wastewater Treatment Plant in Hong Kong Island's South District were running into trouble. The rocky coastal...
Geomechanics of Subsidence Due to Pumping of Groundwater
In this talk we describe a nonlinear theory for the classical problem of pumping of groundwater from a layered soil. The model soil system consists of three horizontal layers where a very...
High-Resolution Interwell Seismic Experiments in Sedimentary Formations
High-frequency interwell seismic data were acquired to examine full waveforms recorded in the pulsed mode and in the swept mode as well as to perform traveltime inversion tomography for...
A Wax-Coupled Borehole Seismic Detector for High-Resolution Measurements
A triaxial borehole seismic detector was developed for high-resolution measurements at frequencies up to 2,000 Hz. Applications for this detector include three-component shallow reverse...
The Initial Exploration of Mars: Rationale for a Return Mission to Chryse Planitia and the Viking 1 Lander
The concepts behind planning a landing site on Mars are discussed. Based on the engineering constraints and the scientific objectives which will likely be imposed on the first few missions...
Multiple Booster Spaceports
Multiple Booster Spaceports examined launching an entire class of space boosters, both current and future, from a single spaceport. The United States presently launches four distinct classes...
Launching Facility Constraints on the Space Exploration Initiative
The Space Exploration Initiative (SEI) proposes large space programs such as a human mission to Mars and the establishment of a lunar base. These programs will require massive logistical...
Launch Facilities as Infrastructure
Many of the launch facilities in this country impose inefficiencies on launch service providers due to the way they have been constructed. To improve launch operation efficiency and to...
Characteristics of High-Speed Runway Exits for Airport Design
This paper addresses some of the geometric design and operational characteristics of high-speed runway exists. Lateral and longitudinal runway constraints limiting the use of high-speed...
Effective Airport Environs Planning in the 1990s
A properly coordinated environs planning effort provides a guide for development and redevelopment of the land and facilities surrounding the airport. Airport environs planning, coupled...
Minneapolis/St. Paul International (MSP) Part 150 Implementation Design Overview
In February 1991, Matropolitan Airports Commission (MAC) selected the consulting team of Aviation Planning Inc., Wyle LAboratories Inc. and the Center for Energy and the Urban Environment...
Studies Related to Aircraft/Runway Friction Performance
Gaining a better understanding of the many factors influencing the tire/runway friction interface is the aim of several ongoing NASA Langley research programs. Results from studies conducted...
Traffic Data Collection: What Really Needs to be Done?
The collection of 'existing' traffic data such as the 24-hour counts, turning movement counts, driveway volumes, and vehicle classification counts near the proposed project site becomes...
A Guideline for Determining Minimum Threshold Requiring Traffic Impact Studies
Over the years, a number of localities have developed and adopted some form of traffic impact assessment (TIA) guidelines. As part of this study, an informal survey conducted showed that...
The Foundation for a Successful Traffic Impact Analysis
Both governmental agencies and private developers use the information developed in a traffic impact analysis (TIA).Traffic Impact Studies can be an important tool in efforts to maintain...
Analyzing Fast-Food Drive-Up Window Site Impacts
Peak-period queueing at a fast-food restaurant drive-up window was observed. The study found that queueing behavior equations based on random arrivals and service times overestimated the...
Comparison of Delay and ICU Analyses?Case Study
Traffic Management Initiative was a petition-based referendum that sought to limit traffic impacts of proposed or planned development through the use of more stringent transportation planning...
ICU?A Method of Analyzing Signalized Intersections
There is a need for decision makers, developers and the public to understand the potential traffic impacts of site development. Signalized intersection operations are a primary indicator...
