New Austrian Dam Side-Channel Spillway
The Loma Prieta earthquake of 17 October 1989 damaged the chute spillway at the Austrian Dam near San Jose, California. The replacement spillway, with a higher design discharge of 11,500...
Supply of Large Woody Debris in a Stream Channel
The amount of large woody debris that potentially could be transported to bridge sites was assessed in the basin of the West Harpeth River in Tennessee in the fall of 1992. The assessment...
Slim-Floor Beams: Design Criteria and Structural Behaviour
Partially concrete-encased steel beams are mostly employed due to their natural resistance to fire, but there may also be other reasons, e.g. to obtain smaller depths of construction....
Pin Piles Save Silos
The United Grain Corp. annually ships about 200 million bushels of wheat and other grains to destinations around the world from its leased facility on the Columbia River at Vancouver,...
All Dressed Up
Its location at 660 Madison Avenue will put the new home of clothier Barneys New York in the heart of Manhattan's exclusive midtown shopping district, but the $120 million...
Seismic Design of Multi-Story, Wood-Framed Buildings
The seismic design and analysis of wood-framed structures is relatively simple; however, the challenges that present themselves within this design medium are shear and overturning force...
LRFD for Timber Structures
The use of load and resistance design (LRFD) methodologies is increasingly becoming the standard analysis procedure for engineering design. The concrete industry has used a variation of...
Structural Fire Resistance Design of Wood Beams and Columns: A Comparison of European and North American Practices
North American and Eurocode design methods for fire-resistive exposed wood members provide a very good example of the translation of research into practical engineering design procedures....
Using Wood as Structural Material: Some Environmental Considerations
Against a background of growing public awareness of the potential dangers of global warming resulting from increasing concentrations of carbon dioxide in the atmosphere it is suggested...
21st Century Timber Engineering
Timber engineering is moving into the 21st Century faced with challenges in technology, governmental mandates and environmental concerns. Engineers are continuously being challenged in...
Beach Nourishment with Aragonite and Tuned Structures
The first full-scale use in the United States of imported aragonite sand for beach restoration was undertaken at Fisher Island, Florida, between December 1990 and April 1991. About 20,000...
Alternative Study for the Breakwater and Fishing Pier Rehabilitation at Playland Park, Rye, New York
An alternative study was conducted to determine that existing condition of a deteriorated timber pier and a rubblemound breakwater, and to develop alternative rehabilitation plans leading...
Sylvan Beach Pier Rehabilitation Study
The Sylvan Beach Pier is a navigation guide jetty located at the east and of Oneida Lake in Oneida County, New York. It protects the entrance to the New York State Barge Canal which crosses...
A Case of the Shakes
New York City's unusual Terrace on the Park offers dining and dancing in a catered ballroom that stands six stories above the ground on four supercolumns. But when guests...
Free Vibration Analysis of Asymmetric Buildings
A simple procedure for free vibration analysis of asymmetric buildings is presented. This method assumes that each floor is a rigid diaphragm with three degrees of freedom (two lateral...
Vortex Suppression in Wet-Pit Pump Intakes
Two distinct examples to suppress both air-entraining and boundary-attached subsurface vortices in large vertical pump intakes are presented that were developed by means of hydraulic model...
Reliability-Based Specification for Engineered Wood Construction
A three-year, industry-sponsored effort has resulted in the development of a reliability-based, load and resistance factor design (LRFD) Specification for wood construction. Improvements...
Load Duration and System Effects in LRFD for Wood Construction
The wood industry is developing a Load and Resistance Factor Design (LRFD) speciification for wood construction using probabilistic concepts. An analysis based on statistical models for...
International Harmonization of Reliability-Based Timber Engineering Design Codes
An overview is presented on reliability-based timber design code activities in various major timber producing and consuming countries. The overview is based on information generated through...
Serviceability Analysis of Wood Beams with Creep
The effect of creep deformations on the serviceability reliability of single, dimension lumber wood beams is examined. A viscoelastic stress-strain relationship is used to model the time-dependent...
