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...

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....

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...

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...

Keeping Sand at a Standstill
Construction of roads, railroads, pipelines and other facilities removes the native vegetation from sand dunes. As a result, sand movement starts and entire dunes may become active. This...

The Effects of P-Delta and Semi-Rigid Connections on Response Behavior of Inelastic Steel Frames Subjected to Cyclic and Seismic Loadings
A numerical method is presented for analyzing semi-rigid connected steel frames subjected to various time-dependent excitations with consideration of damping, nonlinear material behavior...

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...

Structural Applications of SIFCON
SIFCON (Slurry Infiltrated Fiber CONcrete) is a relatively new composite material utilizing steel fibers in a cement-based matrix. It differs from conventional steel-fiber-reinforced concrete...

Behavior of Concrete Bulkheads in Salt Drifts
Parameters studies of the behavior of a plug made from expansive concrete have been performed. Such plugs are now being field tested for sealing boreholes, shafts and drifts at an underground...

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...

Effects of High Pressure and Temperature on HCP
A modification of fabrication techniques for cement paste can significantly affect its properties. Specifically, the static compressive strength can be increased over that of specimens...

Avoiding Cracks in Brickwork
Many aspects of movement and differential movement have been discussed. However, other movements and effects of movement that have not been discussed may also affect 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...
