Crossing the Hollandsch Diep
The design/build team charged with creating an aesthetically pleasing bridge in the Netherlands for high-speed rail faced tough requirements, among them tight construction tolerances and...
Fast Track
The high-speed magnetic levitation rail is now in operation in Shanghai - the first of its kind in the world - demonstrates that this extraordinary technology can move people in a way...
Advancing Under London
Bored tunnels account for more than 20 percent of the Channel Tunnel Rail Link, the high-speed rail line that will connect the Channel Tunnel with London upon its completion in 2007. In...
Advances in Buoy Technology for Wind/Wave Data Collection and Analysis
Considerable advances have been made recently to reduce the cost of gathering meteorological and oceanographic data from coastal waters, especially for meteorological and oceanographic...
A Grand New Bridge
Approximately 65 km south of Seoul, rising above the Asan Bay, the Seohae Grand Bridge now stands as the longest bridge in South Korea. The 9.4 km long cable-stayed bridge, which runs...
Traffic-Calming Basics
The use of traffic calming measures, such as speed humps, traffic circles, and lane narrowings, is becoming more popular in the United States as a way to reduce vehicle speed and traffic...
Rebuilding History
Deterioration of the second-oldest multiple-arch masonry viaduct in the country�in Canton, Mass.�threatened its ability to continue carrying Amtrak's Northeast Corridor trains,...
Tornado Aftermath: Questioning the Tools (Available Structural Engineering Special Issue Only)
In May 1997, several tornadoes hit central Texas. The strongest of these killed 27 people and destroyed about 40 single-family houses on the outskirts of Jarrell, north of Austin. A post-storm...
Accuracy of a 3D Hydrodynamic Model Verification due to the Relative Magnitude of Forcing Functions
An investigation of relative magnitude of forcing functions in a 3D time-varying hydrodynamic model verification has been performed by identifying some extreme forcing events for an estuarine...
Proposed Hurricane Wind Speeds for ASCE 7-95
A 2-3 second peak gust wind map has been proposed for the wind load provisions of ASCE 7-95, now in draft form. On the hurricane coast, speeds from published Monte Carlo analyses were...
Averaging Time and Maximum Speeds in Hurricanes
This paper discuses wind speed data obtained during Hurricane Andrew around Miami International Airport, at six anemometer locations which make up the wind shear warning network. Data...
Hurricane Windspeeds at Inland Locations
A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...
Criteria for Acceptable Wind-Induced Motions
This paper discusses criteria for evaluating acceptable wind-induced building motions. The paper draws on the results of moving room experiments and the performance of actual buildings...
Gust Speeds in Hurricanes
Based on strip-chart records of wind speeds representing 11 recording stations and four hurricanes, it is concluded that gust factors for hurricanes generally exceed the gust factors proposed...
Extreme Winds Estimation by `Peaks Over Threshold' and Epochal Methods
With a view to applying the 'peaks over threshold' method to the estimation of extreme wind sped data, we perform Monte Carlo simulations for which the parameters of the population distributions...
On Hurricane-Generated Seas
Two different situations in the relationship between wind speed and sea severity during hurricanes (and tropical cyclones) are clarified from analysis of measured data obtained by NOAA...
Predicting Wave Spectra With a Third Generation Spectral Wave Model
the ability of the third generation spectral wave model, 3GWAM, to simulate frequency and directional spectra during a northeast storm of October 1990 along the U.S. mid-Atlantic coast...
The Re-derivation of the NDBC Wind-Wave Algorithm
The National Data Buoy Center (NDBC) currently manages a network of 57 moored buoys and approximately 7 Coastal-Marine Automated Network stations on off shore platforms which transmit...
The Determination of Typhoon Design Wave By Synthetic Probibility Method
In summer and autumn, typhoons always take place in the northwest pacific. in the northern hemisphere, the typhoon is a large, anticlockwise, atmospheric eddy. Due to the strong wind speed,...
