A Natural Cleanup
For almost 30 years, nonvolatile petroleum hydrocarbons from used motor oil, diesel, gasoline and other automotive fluids had been released to an oil sum at a truck-maintenance facility...
Fast Foundation for Soft Clay
This article describes the detailed foundation work and high-capacity piling design for a flue gas desulfurization (FGD) retrofit system for the Lambton Generation Station in Ontario,...
Banking on a Bridge
Completing the geotechnical design for the approach embankments and foundations for the Charter Oak Bridge, which crosses the Connecticut River between Hartford and East Hartford, Conn.,...
Seismic Design Criteria for Transporation Structures
Presented is a discussion focusing on two critical issues which must be resolved when setting seismic design criteria for important transportation structures such as those supporting elevated...
Wind Engineering?Engineering for Wind Damage Mitigation
The establishment in 1970 of a new engineering discipline, wind engineering, was motivated by property damage caused by windstorms of 1970 known as the Lubbock Tornado and Hurricane Celia....
Controlling the Seismic Behavior of Precast Concrete
Precast concrete has, through the years the years, acquired a bad reputation insofar as its ability to withstand earthquake is concerned. This reputation, though reasonably based, is not...
Design Criteria for Seismic Connections in Precast Concrete
The seismic behavior of precast concrete is contrasted with that of cast-in-place and the conditions that precast must satisfy are reviewed. Design criteria and possible strategies for...
Ductile Connections for Precast Concrete Frame Systems
This paper describes a research program to investigate the behavior of ductile connections between precast beam-column elements. The objectives of the program are to provide rational design...
Simulated Earthquake Ground Motions for Design Purpose
In this paper, firstly, it was clarified that there is a case where in the long-period range there is seen a tendency to follow the ?+-2$/ model approximately while in the short-period...
Safety Enhancement of Bridges with Seismic Isolation Bearings
This paper summarizes the experimental and analytical studies done at Dept. of Civil Eng., Kyoto Univ., on application of base isolation bearings to highway bridges and the Menshin (base...
Buildings with Response Control Systems in Japan
Today, there are more than 30 buildings with response control systems. The system is defined as one that suppresses or controls the response to the vibrational motion input of the buildings,...
Inelastic Behavior and Seismic Design of a Highway Shield Tunnel
Nonlinear behavior of shield tunnels required for seismic design by means of Seismic Deformation Method is presented based on dynamic loading tests. Application of the test results to...
Rocking Behavior and Retrofit of Tall Bridge Piers
In the aftermath of the damage to the San Francisco Oakland Bay bridge, due to the 1989 earthquake, a comprehensive study of the seismic behavior of the bridge was undertaken. This paper...
Seismic Performance and Retrofit of the Golden Gate Bridge
The Golden Gate Bridge has served for over fifty years as a vital transportation link connecting San Francisco with the area to the north. The Bridge is owned, operated, and maintained...
Seismic Design Considerations for Uplifted Tanks
An evaluation of the most commonly used seismic design procedures for unanchored tanks is presented. It is noted that current standards are inconsistent in predicting the behavior of unanchored...
Input for Seismic Design of Major Structures
Effective seismic input considering the soil-structure interaction or soil-pile-structure interaction is presented. This approach takes the seismic wave as primitive input and considers...
Nonlienar Seismic Response Analysis of Shanghai Yangpu Bridge
The Yangpu Bridge is a long-span composite cable-stayed Bridge in which the superstructures is designed as a floating system to withstand the strong earthquakes. The nonlinear seismic...
Response of Isolated Structures to Recent California Earthquakes
A significant amount of research and development, shake table testing computer modelling and real world applications have been performed with the seismic isolation design concept in the...
Response of Base Isolated Buildings in Japan to Recent Earthquakes
On February 2nd in 1992, more than 20 base isolated buildings in Tokyo experienced an earthquake of JMA seismic intensity 5. In this event, many acceleration records of isolated buildings...
Evaluation of Code Accidental-Torsion Provisions Using Earthquake Records from Buildings
Building code provisions for accidental torsion are evaluated from analysis of earthquake-induced motions of three nominally-symmetric-plan buildings. The results demonstrate that the...
