Restoration of Navy LTA (Lighter Than Air) Hangars
In 1942 and 1943 the Government constructed a series of 16 blimp hangars at ten Naval Air Stations along the east coast, west coast and gulf coast. The hangars erected in pairs housed...

Hypars and Wood Shells?The Boston College Recplex
For the past twenty years, we have been involved in the design and construction of intermediate span wood hyperbolic paraboloid. During that time the spans have ranged from 50 ft. to 200...

Nondestructive Evaluation of Timber Bridge Piles
A nondestructive technique for the determination of the in-place strength of timber bridge piling is presented herein. The testing technique is the ultrasonic wave propagation method in...

Rapid Assessment of Seismic Vulnerability
The choice of a seismic damage assessment method depends fundamentally on how the assessment will be used, but always involves definition of the expected ground motion and the structure...

ATC Methodology and Data for Rapid Assessment of Seismic Vulnerability
Recently developed Applied Technology Council (ATC) methodology and data provide a technical basis for rapid assessment of structure seismic vulnerability. Methodology developed under...

Solving Nonlinear Equations on a Hypercube
Certain classes of nonlinear systems of equations, such as polynomial systems have properties that make them particularly amenable to solution on distributed computing systems. Some algorithms,...

Supercomputers and their Impact on Civil Engineering
The increasing complexity of today's civil engineering applications requires increasing detail and analyses with associated increased demands on computer resources. At the...

The Promise of Supercomputers
This paper briefly reviews the classification and general architecture of supercomputers: their capabilities, promise, current and projected limitations are considered. The author reviews...

CAPPS: Custom Architectured Parallel Processing System
CAPPS (Custom Architectured Parallel Processing System) is under development at Paragon Pacific Inc. , Torrance, CA, for the solution of computationally intensive engineering problems....

Lessons Learned from Design, Construction, and Performance of Hydraulic Structures
The intent of this publication is to provide lessons learned, both positive and negative, from activities associated with design, construction, and performance of hydraulic structures....

Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...

Going Afield with Instrumentation
An overview of field measurements and instrumentation in civil engineering is presented. System components are described for the practicing design or construction engineer involved in...

Microtunneling: No Pipe Dream
Microtunneling machines developed in Japan and Germany can help install pipes, ducts and cables without disrupting urban activities at street level. A microtunnel is defined as having...

Approaches to Acceptable Risk
Acceptable risk has numerous meanings, that are derived from its having been defined in multiple arenas and by multiple groups. This paper describes several approaches to the question...

A System Framework for Engineering Risk Analysis
A mathematical system framework is developed to model a series of criteria called performance indices (PI) related to engineering risk in water resources. Such criteria include reliability,...

The Status of Risk Analysis in Water Resources Engineering
Acceptance of probabilistically based risk-analysis evaluation methods among water resources engineers is rather slow, as it is among other engineering specialities. Academic researchers...

The Risk Factor in Water Resources
Risk is inherent in nature and society, while uncertainty depends on investigations. Decision making in water resources is most often a deterministic selection of dimensions which divide...
