Impact-Echo Strikes Home
Diagnosing flaws without destroying the structure is the first step to cost-effective repairs. Impact-echo is one of the more successful nondestructive evaluation (NDE) methods that have...

Engineering a Landslide
A slope failure in northwest Alabama has been stabilized using a system of grouted INSERT piles to provide load transfer across the failure surface of the slide. This system, referred...

Advances in Underground Pipeline Engineering II
The first international conference on Advances in Underground Pipeline Engineering was held in 1985. Some 50 authors and over 300 delegates from 20 countries took part in the presentations...

Waste Containment Facilities
This book presents a comprehensive description of recommended procedures for construction quality assurance (CQA) and control (CQC) for waste containment facilities. Chapter 1 describes...

Study of Interaction Between Pneumatic Spherical and Cylindrical Form Shells Subjected to Wind Pressure
In the design of pneumatic membrane structures, analysis of stress and deformations of structures subjected to wind is among the most important requirements. For the purpose of studying...

Trenchless Relief
During wet weather, stormwater infiltration/inflow into the sewer system increases wastewater flows by 8-12 times the average dry weather flow in several interceptors operated by the Central...

Enabler Chassis Features and Mobiltiy Analysis
The Enabler is a proposed Lunar Base work vehicle. The unique construction of the Enabler's six-wheeled chassis provides unusual articulation for steering, balancing, and overcoming obstacles....

Spacecab: A Concept for Commercial Human Spaceflight
This paper will describe the Spacecab conceptual design and operational scenario. Spacecab is not necessarily a unique design solution but it does illustrate a design philosophy that differs...

A Dome For the 21st Century
Putting a circular dome on a square building--the classical architectural design challenge--takes on new proportions at the Federal Building and Courthouse in Charleston, W. Va. The 170...

Safety Assessment of a Chemical Reactor Vessel
The potential explosion loadings on a chemical reactor vessel is described in this paper. The potential loads presented provide a basis for designing spherical storage vessels which will...

Monitoring of Structures During Repair of Underground Utilities
A collapse of underground utilities at a power plant required the constant monitoring of the surrounding structures during excavation and replacement of the damaged pipes. A computer-based...

Dynamic Testing of Unreinforced Brick Masonry Infills
A significant seismic hazard may exist when unreinforced masonry infill panels fall out of their surrounding frames as a result of excessive accelerations applied normal to their plane....

Uplift Resistance of Plywood and OSB Roof Sheathing
A test program to determine the resistance of plywood and OSB roof sheathing to uplift pressures created by wind flowing over a residential roof structure will provide valuable data to...

A Probabilistic Approach to the Response of Tall Buildings to Wind Loadings
Tall buildings constructed in recent years are light in weight, flexible and low in damping. This is the consequence of using lighter material with higher strength, and fewer interior...

Gust Speeds in Hurricanes
Based on strip-chart records of wind speeds representing 11 recording stations and four hurricanes, it is concluded that gust factors for hurricanes generally exceed the gust factors proposed...

Compressive Strength of Large Scale HSLA-80 Steel Cellular Sections of a Double Hull Ship Structure
An analytical and experimental large scale test program was conducted to investigate the instability failure modes of cellular double hull box sections. The main emphasis of the study...

Structural Tests on the Suspen-Dome System
The 'suspen-dome' system, which the authors have developed, consists of a single-layer truss dome and a cable structure. The present paper deals with the results of structural tests conducted...

The Daytona Beach Large Wave Event of 3 July 1992
The fundamental mechanisms behind the anomalous large wave which struck Daytona Beach on 3 July 1992 are addressed. Although the wave was originally believed to have resulted from a submarine...

The Significance of Hydrodynamic Forces in Coastal Embankment Design
The dynamic forces of sea water and backfill soil acting on coastal embankment are analyzed by using a new finite-difference method. The Euler's equation and continuity equation are used...

Modeling Municipal Water Demands for a Pump Station Area
The Chasewood Pump Station/Residential Area in southwest Houston was selected for a detailed analysis of ground and surface storage water pumping by a University of Houston and City of...
