Three-Dimensional Circulation Modeling of the Coastal and Ocean Environments
Incursion of the loop current, a meandering feature of Gulf of Mexico large-scale circulation, may produce large hydrodynamic forces on the offshore structures. The present study is to...
A New Concrete Armor Unit for Breakwaters: The Beta Block
The aim of this paper, is to present a new artificial block for the protection of breakwaters. This armor unit, named BETA, has been designed and tested in the Coasts and Harbors Studies...
Hydraulic Design of Offshore Breakwater in Sergipe, Brazil
A Petrobras (Petroleo Brasileiro S.A.) marine terminal was recently constructed in Sergipe, Brazil (Figure 1). The offshore breakwater was initially designed in a conventional way, but...
Stability of Accropode(R) and Comparison with Parallelepipedic Block
This paper describes the tests which were performed on physical models with irregular waves, to determine the hydraulic stability of the Accropode(R)...
Mobile-Bed Physical Model Tests for the 1992 Olympic Harbour
The undistorted physical model is described which allowed the measurement of the wave induced velocity field along the main breakwater, and also in Somorrostro Beach (Barcelona). The current...
Piles Under Dynamic Loads

Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...
Small Utility GIS
Geographic information systems are revolutionizing much of the civil engineering field, providing engineers and managers with a new tool to relate databases and maps. But despite the benefits...
Measured to the Max
Engineers looking to model the behavior of a structure under seismic conditions often ignore the best source of data available: the building itself. Full-scale measurements of vibrations...
The Great Chicago Flood of 1992
In April of 1992, a breach in a freight tunnel caused the river that flows through Chicago to pour into city building basements, causing the city to shut down. Critical utility systems...
Perils of Point Loma
Rupture of the Point Loma sewage outfall in San Diego on Feb. 2, 1992, sent 180 mgd of primary-treated sewage coursing into shallow waters off the city's coastline. The article...
Managing for Profit
Clients hire firms today for their ability to manage, not just design and draw. Project managers must address owner requirements for cost, quality and schedule. The three are inseparable....
Earthquakes: A New Look at Cracked Masonry
Economics, fears of liability, and a strict damaged-buildings repairs ordinance have contributed to an extensive delay in the repair of masonry-infill buildings in earthquake-stricken...
Tensile Terminal
Few can miss a fabric roof that covers a 1.45 million sq ft area. The one covering the Denver International Airport's Landside Terminal complex (reportedly the nation's...
Dome Over Orlando
The article describes Orlando's new City Hall, a 267,000 sq ft nine-story reinforced concrete tower, clad in granite-aggregate precast concrete panels and topped by a 120...
School Is In Session
Cost overruns, project delays and the city bureaucracy have given school construction a bad reputation throughout the U.S., particularly in urban centers. But as other construction markets...
MUT1D: User-Friendly One-Dimensional Thermal Model
MUT1D is a microcomputer-based heat conduction model which uses implicit finite difference techniques to determine the thermal regime and track the movement of the phase change front in...
Numerical Analysis of Frost Shields
The term 'frost sheilding' has been used to describe the practice of using flat stock rigid insulation materials burial above a water or sewer pipe to reduce...
Computer Predictions of Thaw Beneath Gravel Embankments on Warm Permafrost
A computer model was used to simulate the freeze-thaw effects of gravel embankments on warm permafrost typical of south-central Alaska using a one-dimensional finite-difference code, FREZ1D....
Impact of Cold Weather on Building Construction Scheduling
Weather impact on a building construction schedule is often significant in cold regions. Most deterministic scheduling methods are unable to directly account for the effects of weather...
