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 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...
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 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...
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...
Long-Span Design for Seismic Forces?A Case Study of the Anaheim Arena
The design for the Anaheim Arena roof evolved in response to the strict requirements for a structure in a seismic zone 4 location. The support of the 329 ft. (100 m) by 444 ft. (135 m)...
Blast-Damaged Concrete Structures in Beirut
This paper describes the effect of blasting loads on structural members. It identifies predominant structural systems in war-damaged zones of Beirut and to explain typical damage mechanisms....
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...
Steel Plate Energy Absorbers for Improved Earthquake Resistance
This paper discusses results of an combined experimental and analytical investigation on seismic response of frame structures using welded steel triangular plates as added damping and...
Response of Equipment in Structures Supported on Resilient-Friction Base Isolators Subjected to Ground Motion
In this paper, the response of equipment in structures on a particular friction-type device, the resilient-friction base isolator, is examined. The R-FBI is composed of layers of Teflon...
Robust Control for Buildings Under Earthquake
Robust control techniques are applied to civil engineering structures subjected to earthquake excitation. Full state feedback and observer based control laws are used to reduce the response...
