Aeroelastic Study of Long Span Suspension Bridges: the Messina Crossing
This paper deals with wind actions on long-span suspension bridges. Particular reference is made to the Messina Strait Crossing. Problems encountered in this study, both for deck and towers,...
Full Model Wind Tunnel Tests for the Akashi Kaikyo Bridge
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...
Effects of Drifting on Snow Loads on Large Roofs
In areas that experience significant snow fall, snow loads typically produce the governing environmental load cases for a large span roof. Therefore for large span roofs there are considerable...
Wind Loads on Arena Roofs Using Aerodynamic Models
The concept behind an aerodynamic wind tunnel model used to predict dynamic response to wind excitation is the generalized load in a particular natural mode of vibration is measured ,...
Design Wind Speed and Design Criteria of Buildings
Design load recommendations of Architectural Institute of Japan(A.I.J.) are revised according to a common principle to all kinds of loads. The basic wind speed is defined as the annual...
Prediction of Wind-Induced Responses and Wind Loads
The Recommendations for Wind Loads of Buildings and Structures of the Architectural Institute of Japan have now been updated. This paper presents the drafts of the new Recommendations...
Wind Resistant Design and Response Control of Tall Building
This paper presents an overall view of the wind resistant design and response control of the tall buildings in Japan, the Crystal Tower in Osaka and the Landmark Tower in Yokohama. The...
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...
The Engineer's Role in Reducing Curtainwall Failures
For a variety of reasons, engineers have abdicated responsibility for curtainwall design. Failures of curtainwall components are very common, leading to expensive repairs and even complete...
The Effective Use of Fire Ratings
Any consideration of components for construction must take into account the performance of those components when they are exposed to fire. Codes, standards, and fire ratings provide some...
Things That Fall?Lessons from Some Construction Accidents and Structural Failures
The causes and results of several construction accidents are reviewed. The lessons to be learned from such a summary are that all too often the simplest oversight leads to catastrophic...
Tuned Mass Damper in Tall Building Design
Viscoelastic dN and tuned mass dampers are often used by tall building designers to control wind-induced building vibrations resulting from such phenomena as vortex shedding, galloping,...
Vortex Shedding Induced Fatigue Fracture of Mast Tower
The fracture of a pair of 60m high circular steel masts is investigated. The design criteria and fabrication practices are reviewed. The cause of failure is related to the fatigued condition...
A California Tower: Response to Seismic Forces
First Interstate World Center is a signature building for the city of Los Angeles. The granite clad tower with its serrated facade rises 1,018 ft. above street level. It is the tallest...
85 Stories in Kuala Lumpur?The 5th and 6th Tallest Buildings in the World
A concrete core and cylindrical concrete tube structure provides a safe, elegant, efficient and constructible solution to the challenge of designing the world's 5th and 6th tallest buildings,...
Seismic Behavior of High Strength Concrete Columns
Information on the ductility of high strength columns in seismic areas has been scarce. The available information is based mainly on small test columns subjected to monotonic concentric...
Seismic Vulnerability and Upgrading of Nonductile Reinforced Concrete Frames Using Passive Supplemental Dampers
The effects of vulnerable details of lightly reinforced concrete frames constructed prior to the 1970s is evaluated from tests conducted of two beam/slab/column subassemblages drawn from...
High-Strength Concrete Joints Under Cyclic Loading
This experimental investigation was undertaken to check the validity for high-strength concrete beam-column joints of recommendations made by ACI-ASCE (American Concrete Institute-American...
Seismic Strengthening of Johnstown Tank in Lakeside, California
Seismic overturning moments exerted on liquid storage tanks may be resisted by a system of anchor bolts if the shell could be adequately anchored to its base, or by allowing the base plate...
