Berm Placement Planning Study at Breton Island, Louisiana
This paper identifies tools that are being utilized to determine the most environmentally beneficial location for a nearshore berm to be constructed at Breton Island, Louisiana. The computer...
Sedimentational Aspects of Erdemir Port (Eregli, Turkey)
This paper reviews available information on environmental conditions, historical data on sea bed topography and dredged volumes for understanding sedimentational processes at or near the...
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...
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....
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...
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...
Construction Loads on Floors: Results of a Survey
A survey of post-shorting construction loads on floors of multi-storey buildings is described. The estimated parameters of a probabilistic model of the peak (transient) loads are reported....
Floor Live Load Models and Pattern Load Effects
Probabilistic models of sustained live loads and equivalent uniformly distributed loads are discussed with regard to pattern load effects. A simple equivalent pattern load is identified...
The Crown and the Curtain Wall
Crowning the complex curtainwall of an 870 ft concrete tower with a 150 ft high crown of aluminum masts in concentric rings above the 60th floor required ingenuity and extraordinary cooperation...
Mining for Building Expansion
Engineers adapted mining techniques to tunnel under a vibration sensitive manufacturing operation to create new working space below. IBM workers needed more working space at their Vermont...
The Growing Meet Market
The Delaware cities of Dover and Wilmington are only 5 mi apart. Their combined populations barely exceed 100,000. Yet each city is planning to build a new convention center to corner...
COFDEX: Composite Floor Design Expert
A knowledge-based system, called COFDEX, is presented for integrated minimum cost or minimum weight design of composite floors in multistory buildings. Developed in the expert system programming...
The Application of a Geographical Information System to Resource Management?The UK Offshore Sand and Gravel Case
In the United Kingdom coastal and offshore environments, the extraction of sand and gravel from the seabed requires a high level of professional management, because of the varied and often...
The Use of Aragonite as an Alternate Source of Beach Fill in Southeast Florida
The first full-scale use in the United States of imported aragonite sand for beach restoration was initiated at Fisher Island, Florida, in December, 1990. The project involved placement...
Access Floor Response Spectra for Equipment Line-Ups in Telecommunications Central Offices
Modern telecommunications central offices very often utilize access floors to support equipment line-ups. An analytical study was carried out to study the seismic response of equipment...
Responses of a Secondary System and Its Supporting Hysteretic Structure to Seismic Excitations
We consider an N-story building that supports 1-degree-of-freedom equipment on one of the floors, and examine both the building's and the equipment's responses...
Lifetime Behavior of Wood Structural Systems
Reliability based design of wood structural systems requires knowledge about the lifetime behavior of the system. The 50 year lifetime behavior of wood floors and flat roofs was examined...
Haunches and Hangers
The $210 million VA Medical Center at Houston features a structural system as innovative for the 1990s as the interstitial space concept was in the 1960s. The medical center, designed...
