Seismic Analysis of Meloland Road Overcrossing Using Calibrated Structural and Foundation Models
A detailed seismic analysis of the Meloland Road Overcrossing is being implemented to study the response of this bridge during the 1979 Imperial Valley Earthquake. This analysis is based...
A General Hysteresis Model for Wood Structures
To predict the dynamic response of a wood structure, its energy dissipation mechanism and hysteresis behavior must be appropriately modeled. This paper presents a new hysteresis model...
Fire Retardant Treated Wood
The paper explains how FRTW chemicals react with combustible gases. It describes the two types into which FRTW is divided. Misconceptions about FRTW are also addressed....
Fire Endurance Model for a Metal-Plate-Connected Wood Truss
A numerical model has been developed for predicting the fire endurance of a single metal-plate-connected wood truss. Extensive component fire testing was conducted to develop the necessary...
Wind Design and Analysis for the Normandy Bridge
The Normandy Bridge will represent an important progress in the field of cable-stayed bridges, with a main span 856-metre long. This paper explains how the design has been oriented to...
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....
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...
Investigation of a Failed Concrete Joist System
The failure and distress of concrete joists contained in the promenade roof deck of a one-story, college, lecture hall building initiated an extensive investigation to determine the cause...
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...
Current Forensic Courses in Civil Engineering
The ASCE is taking a leadership role in the prevention of failures of engineered facilities. The Technical Council on Forensic Engineering Education Committee recently completed a survey...
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,...
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,...
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...
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...
