In order to carry out final verification of the wind resistance safety of the Akashi Kaikyo Bridge under construction, which has the largest main span of 1,990 m, its full aeroelastic...

Wind Tunnel Testing for the Great Belt East Suspension Bridge
This paper provides an overview of model tests conducted to study and predict the aerodynamic behavior of the proposed streamlined box-girder suspension bridge for the Great Belt Link....

Wind Resistant Design Manual for Highway Bridges
'Wind resistant design manual for highway bridges in Japan' has been published in 1991. Before publication of this manual, there were no authorized wind resistant manuals which can be...

Bridge Aerodynamics and Response Control?Recent Research and Developments in Japan
Bridge aerodynamics and its response control with emphasis on the recent R/D in Japan are reviewed. Aerodynamic countermeasures based on the vibration mechanisms as well as mechanical...

Hybrid Control of Seismic-Excited Bridge Structures Using Variable Dampers
A method of control for seismic-excited buildings or bridge structures using variable dampers is presented. The control method is based on the theory of variable structure system (VSS)...

Behavior of Horizontally Curved Steel Highway Bridges
Horizontally curved highway bridges represent up to 25 percent of the market for new steel-bridge construction each year. However, unanswered questions remain concerning the fundamental...

Bridge Management Research Needs
The present article deals with some aspects of bridge management of particular interest to bridge engineers and to bridge users at the moment. It addresses questions such as life-cycle...

Joint Design in Composite Columns/Steel Beam Structures
The use of a composite building system, utilizing a composite exterior column and a concrete spandrel beam system, proposed by Dr. Fazlur Khan in 1967, is recalled. In the last 25 years,...

Seismic Assessment and Renovation Study for Highway Bridges
This paper is concerned with hazards mitigation on highway bridges due to earthquake ground motions. Damage to transportation systems may occur if the acting faults of May-Shan and Tsu-Kou...

Concrete Arch Bridges for Supporting Steel Conduits of Mingtan Pumped Storage Project
For the Mingtan Pumped Storage Project of an installed capacity of 1600 MW, two parallel waterways have been constructed for conveying flows between the upper reservoir and the lower reservoir...

Design of the Main Bridge of the Huachiang Bridge
The Huachiang Bridge will be reconstructed by erecting the deck structure in two steps to avoid reducing or interfering with the bridge's traffic flow. Both the analysis and the detailed...
