The Heartbeat of the Artery
One of the most ambitious infrastructure megaprojects in recent memory, Boston's $5 billion Central Artery runs the gamut of civil engineering disciplines. Design, highway,...
Reformulation Efforts for Panama City Harbor, Florida
Panama City Harbor is on St. Andrew Bay, an arm of the Gulf of Mexico, about 105 miles east of Pensacola and 230 miles northwest of Tampa. At the request of the non-Federal sponsor, the...
Numerical Modeling of Proposed Kawaihae Harbor, HI
The Kawaihae shallow-draft harbor site is located on the northwest coast of the island of Hawaii, HI. An entrance channel, turning basin, and breakwater currently exist at the harbor site....
Use of Portable Simulator in Designing Channel Improvements for Port of Brownsville, Texas
The Port of Brownsville, located at the southernmost tip of Texas, serves as an import/export port for both southern Texas and northern Mexico. The proposed channel improvement project...
Naval Pier Foundation Design and Construction, Pearl Harbor, Hawaii
The paper presents a case study of foundation design and construction for a pier in Pearl Harbor. The study covers a review of site investigations, laboratory testing, pile selection and...
Subaqueous Disposal Area Development and Mitigation
Development of subaqueous dikes on soft soils extensively utilized geosynthetics. The design adopted a wide-bermed embankment with high-strength geotextile for tensile reinforcement and...
Dutch Experience on Design of Dikes and Revetments
The increased demand for reliable design methods for protecting structures has resulted in The Netherlands in preparing a set of design guidelines for design of dikes and revetments. The...
Application of a Dolos Structural Design Procedure
Dolos concrete armor units are widely used to protect coastal structures. New developments in armor unit strength design permit the armor unit designer to optimize the dolos parameters...
A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...
Coastal Engineering Design Codes in the Netherlands
Dutch research strategy on water defences and the resulting coastal and hydraulic engineering design codes (technical documents) are briefly overviewed. Special attention is paid to organizational...
Seismically Safe, Spectator-Friendly
As 50,000 frightened spectators at Candlestick Park can attest, the Loma Prieta earthquake in 1989 provided chilling evidence of the importance of seismic design in public structures....
Peaches and Concrete
One Peachtree Center, Atlanta's latest highrise tower, will measure 62 stories high (860 ft) with 1.42 million sq ft of office space when completed next July. It will also...
Landfills: Anatomy of Automated Design
California's 360 acre Bee Canyon landfill (completed last year) sits amid a complicated network of narrow canyons with side slopes 300 ft high. As with most landfill projects,...
On the Influence of Seismically Induced Residual Forces on Bridge Abutment Design
The seismic design of bridge abutments depend on the anticipated movement of the abutment during the design earthquake. For seat-type abutments in which the backfill resistance can be...
Analytical Studies on the Seismic Response of Lead Rubber Base Isolated Bridges
Highlights of a study related to the response of base isolated bridges are presented. Four different analytical models are developed and used to evaluate the response of base isolated...
Dynamic Analysis of Sliding Seismic Isolators
The friction pendulum system (FPS) sliding seismic isolators are being used for the seismic isolation rehabilitation of the U.S. Court of Appeals Building, San Fransisco. This paper will...
A Wax-Coupled Borehole Seismic Detector for High-Resolution Measurements
A triaxial borehole seismic detector was developed for high-resolution measurements at frequencies up to 2,000 Hz. Applications for this detector include three-component shallow reverse...
Sensitivity of Lifeline Response to Models for the Spatial Incoherence of the Seismic Ground Motions
The sensitivity of the response of above-ground and buried lifelines to different models describing the spatial variability of the seismic ground motions is examined. It is shown that...
Shear Resistance Models for Concrete Bridges
Statistical models are developed for the shear resistance of concrete bridge girders. Two structural types are considered: reinforced concrete T-beams and prestressed concrete AASHTO girders....
A Multiple Disk Centrifugal Pump as an Artifical Ventricle
A pulsatile, multiple disk, centrifugal pump has been analysed and tested for potential use as an artificial ventricle. The pump is similar to a Tesla Turbine design which consists of...
