A Quasicrystal for Denmark's Coast
The first true quasicrystal structure will have been built in the fall of 1993 at COAST (The Center for Art, Science, and Technology at the Danish Technical University). With 600 aluminum...

RC Beam-Column Element for Nonlinear Frame Analysis
Recent studies have shown that beam-column finite elements that enforce equilibrium rather than compatibility along the element are better suited for the description of the strength and...

A Comparison of Three Wave-Measuring Buoys
We compare the performance of three wave-measuring buoys: a Seatex WavescanTM, an Endeco/YSI WavetrackTM,...

Practical Solution of the Flexibility to Stiffness Transformation Problem With a Mathematical Assistant for the Personal Computer
This paper will show how a relatively complicated structural mechanics problem can be solved easily with a symbolic manipulation program. Specifically, the authors will demonstrate how...

Concrete over the Connecticut
The existing Baldwin Bridge carrying I-95 across the Connecticut River between Old Lyme and Old Saybrook, Connecticut, constructed in 1948, is functioning at maximum capacity with modern...

Tension Pile Test
The California Department of Transportation is conducting FULL SCALE AXIAL LOAD TESTS of 34 piles. This research project/proof test is being jointly conducted by public agencies (Caltrans...

Investigation of Full-Scale Performance of Structures?Research Potentials
It is well known that actual, or true, behavior of completed structures does not necessarily conform to often simplified analysis predictions. This may be due to any of several reasons...

Design of Stay Cables
Cable stayed structures, consisting of slender superstructure, stay cables and pylons are optimal systems for long span structures with regard to design an economy. The important function...

Analysis and Design of SFRC Structural Elements
This paper presents and validates practical methods for flexural, shear and torsional analysis and design of fibrous reinforced concrete structural elements. The effects of both fiber...

The Use of Built-Up Compression Members?A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....

Built-Up Compression Members for Noval Structural Systems
This paper discusses built-up compression members used in novel structural systems for two high-rise buildings: InterFirst Plaza at Dallas Main Center and Columbus Center in New York....

QST Rolled Shapes, a New Generation of HSLA Compression Members
With the development of the Quenching and Self-Tempering (QST) process by the Luxembourg steelmaker ARBED S.A., a new generation of High Strength Low Alloy (HSLA) rolled shapes has become...

Ambient Vibration Survey: Sunshine Skyway Bridge
An ambient vibration survey of the Sunshine Skyway Bridge was performed. The goal of this survey was to provide field data on the dynamic characteristics of the structure to corroborate...

The Stabilization of Concrete Dams by Post-Tensioned Rock Anchorages: The State of American Practice
Permanent post-tensioned rock anchorages have been used for over twenty years in America to stabilize existing concrete dams and their appurtenant structures. This paper provides a state...

Object-Oriented Finite Element Modeling
The present paper studies the suitability of object-oriented modeling strategies for problems of structural mechanics. After a general discussion of the topic, special emphasis is put...

Accurate and Efficient Element for Analysis of Concrete Structures
Reinforcement details in concrete structures are inherently complex. Therefore, the treatment of reinforcements is one of the most influential factors in the accuracy and efficiency of...

Coastal Planning in British Columbia: Problems and Solutions
British Columbia is the most western Canadian province encompassing 27,000 km of deeply incised coastline and myriad islands and waterways. The mix of varied and often conflicting uses...

Evaluation and Repair of Unbonded Post-Tensioned Concrete Structures
As with other forms of infrastructure, there is an ever increasing need to repair and strengthen unbonded post-tensioned concrete structures. Repairs may be necessitated for a variety...

HUD Concerns: Post-Tensioned Foundations in Texas
An investigation was conducted of post-tensioned slab foundation systems in Texas pursuant to a request from the Headquarters Office's of the U.S. Department of Housing and Urban Development...

The Copper-Clad Library
The design vocabulary for the new Phoenix Central Library includes saddlebags, power bellies, tensegrity and corrugated siding. The saddlebags are copper-clad, steel-framed core structures...
