Decay in Wood Structures
One of the main causes of wood deterioration is decay. Decay causes millions of dollars in damage to timber structures each year. Left unchecked, decay deterioration can become a structural...
Case Studies in Upgrading of Wood Trusses and a Heavy Timber Building
Three case studies in upgrading and rehabilitation of wood structures are presented. One case study relates to three 30m (100ft) span bowstring trusses that had to be cut at various span...
Epoxy Repair of a Glulam Beam
The repair of timber structures by epoxy injection techniques is a recently developed repair alternative. Theoretical and experimental studies have resulted in the formulation of design...
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...
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...
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...
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...
The Hyatt Decision: Two Opinions�The Attorney/Engineers Speak
On the grounds of gross negligence, misconduct and fraudulent misrepresentation, Administrative Law Judge James B. Deutsch recommended that the licenses for the Kansas City Hyatt be revoked...
Computer Assisted Pavement
In Rancho Palos Verdes, Calif. a 4,300 ft. long test installation of the Contained Rock Asphalt Mat (CRAM) Pavement System is expected to have a 50 year life. It cost a third less than...
Rehabbing for Reuse
Case histories of four building rehabilitation projects highlight special challenges to their structural engineers. The Lits Building, Philadelphia, is a collection of eight structures...
Timber in Bridges of West Coast
Experience has shown that timber can function very well as a bridge material. Proper inspection procedures combined with a structured maintenance program can improve the performance of...
The Basics of Water-Resistant Brick Walls
Water-resistant masonry walls of burned clay or shale brick are the result of a conscious effort to produce them, by everyone involved in their creation. Furthermore, owner maintenance...
Winter Highway Construction
The purpose of this paper is to describe a study of the feasibility of constructing highways in the wintertime in cold regions. The study, sponsored by the Alaska Department of Transportation...
