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,...
Tuned Mass Dampers for Towers and Buildings
Tuned mass dampers (TMD's) are used to reduce the response of tall slender structures to resonant wind-induced oscillations. This paper reviews the authors' experience with the design...
Structural Design and Wind Resistance of Fukuoka Tower with T.M.D.
Fukuoka Tower, which was built in 1989, was projected as a monument, a observation tower and a broadcasting antenna with 234m high. In this tower, a Tuned Mass Damper(TMD) was set, in...
On the Numerical Simulation of Wind Loads on Structures
A new methodology for numerical simulation of 3-dimensional turbulent flow based on the use of a Galilean frame and the finite point method is presented. The pressure field of the solutions...
Structural Response Using Stiffness Decoupler
The structural properties of a new stiffness decoupler developed by Hu, Kirmser and Swartz at Kansas State University, and its applications as an energy absorber and a device to isolate...
Relationships with Architects and Owners
There are many issues which affect the relationships between structural engineers and on the other, the owner clients. This paper discusses some of those issues from the point of view...
Wind Hazards Reduction Program
The 1990's mark the International Decade for Natural Disaster Reduction. In this context, the Wind Effects Committee of the Structural Division strongly endorses the establishment of a...
Mitigation of Wind-Created Risks During Construction
Wind damage to structures during construction has been found to be significant and often catastrophic. Structural failures are often the result of wind loads that are far less than the...
Development of Computer-Based Models of Standards and Attendant Knowledge-Base and Procedural Systems
Existing and new technology can be used to develop a new generation of standards that would allow designers to use complex standards efficiently, help standard-writing bodies to detect...
Investigation of Full-Scale Performance of Structures?Research Potentials
It is well known that actual, or true, behavior of completed structures does not necessarily conform to often simplified analysis predictions. This may be due to any of several reasons...
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...
MRT Cable Supported Roof
A cable supported roof structure for Chientan station (R18A) at Taipei Mass Rail Transit system's Tan-Sui line are under construction. Unique wind and cross sectional dynamic effect has...
Steel Alternates for the Hoover Dam Bridge
As input to the Environmental Impact Statement studies of appropriate long span bridges were performed for three alternate corridors across the Colorado River near Hoover Dam. Details...
Bridge Engineering and Life Cycle Cost
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires that all Federal Aid projects must 'consider...the use of life-cycle costs in the design and engineering of...
An Information System on the Performance of Suspension Bridges Under Wind Loads
While most suspension bridges for which information is available, in operation between the period: 1701-1992, have performed satisfactorily under wind loads, a few bridges were destroyed,...
Wind-Induced Vibrations of Tall Buildings Using Tuned Mass Damper
A Lagrange formulation is applied to tall buildings using tuned mass damper. The resulting equations of motion are analyzed using a frequency window method. The method reduces the computational...
Reliability-Based Design of Transmission Towers Under Wind and Ice Loadings
This study suggests a practical but rational approach for the development of reliability-based LRFD criteria for transmission towers under wind and ice loadings in Korea. Based on available...
Buckling of Cylindrical Storage Tanks Due to Unsymmetric Lateral Wind Load
Non-linear finite element analysis is used to study the elastic stability of cylindrical storage tanks subjected to unsymmetrical loads. These cylindrical shells are assumed to be fixed...
Recent Successes in Welding Jumbo Shapes
