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...

Alterations to Old Wood Building
In order to accommodate a new use, a request was made to remove bearing walls supporting the roof of a 42 year-old building and substitute timber posts. The existing nine-foot ceiling...

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...

Evaluation of the Seismic Performance of Buildings
The aim of the paper is to present the different existing methodologies available for the assessment of seismic damage to buildings. The approach aims towards the development of a mini-computer...

Techniques for Estimating Earthquake Probable Loss for Buildings and Contents
The probable maximum loss (PML) is useful for quantifing the seismic risk exposure of a facility and for rational decision making regarding earthquake insurance and seismic strengthening...

Rapid Identification of High Risk Building in Seismic Regions Using Expert Systems
Seismic risk evaluation is a complex problem because it involves many factors such as ground motion, ground failure potential and structural performance with great uncertainties. Many...

Seismic Risk Analysis of a Multi-Site Portfolio of Buildings
A discussion of a methodology that permits the assessment of the seismic risk associated with a group of buildings and incorporates relevant aspects of seismic hazard assessment including...

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....

Guide to Investigation of Structural Failures
Prepared by the Research Council on Performance of Structures of ASCE. This report contains guidelines for conducting an investigation into the causes...

Use of In Situ Tests in Geotechnical Engineering
In the past ten years, many new types of in situ test equipment and many new techniques have been developed. The papers in this volume are concerned with applications of in situ measurement...

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....

Environmental Engineering
Over 80 of the papers presented at the 1986 National Convention on Environmental Engineering are included in this book. The major categories covered include air, noise, and radiation management,...

Managing Two Projects as One
The Port of Tacoma completed a new two berth container terminal and intermodal yard for Sea-Land in May 1985, only 26 months after signing a binding agreement. The project, which also...

So You Came Here to Teach?
A civil engineering department head explains the facts of life to new faculty members. Obtaining research grants and publishing refereed papers are the most important tasks. As for teaching,...

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...
