A Multiple Presence Load Model for Bridges
This paper utilises weigh-in-motion data to simulate multi-lane traffic crossing short span multiple-lane bridges. In this manner the reduction factors for a multiple lane bridge are derived....
Metrication of Construction?A Message to the American Society of Civil Engineers
The author discusses the reasons for metrication of the U.S. construction industry, describes the Canadian experience in this area, and outlines the necessary steps to alleviate the metrication...
Taming Tornado Alley
Some structures�such as nuclear power plants�need complete protection from tornadoes regardless of the high costs of design and construction. Public facilities need protection too, but...
Design of Marina Replacement Facilities
A majority of the waterfront design projects within the State of California are for the replacement of existing facilities since the densely populated shoreline areas are already heavily...
Proposed Seismic Design Method for Piers and Wharves
Current seismic provisions of the 1991 Uniform Building Code (UBC-91) and the 1983 AASHTO Seismic Design Specifications (AASHTO) are compared as they relate to piers and wharves. An alternate...
Container Terminal Gates Flexible Design for a Dynamic Environment
A paper entitled 'Container Terminal Gate Efficiency Hinges on Flexibility' was presented at ASCE Ports '89 by Larry Nye of Cash & Associates Engineers. The paper summarized the...
Fingerprint Identification of Groundwater Petroleum Contamination Using Synchronous Scanning Fluorescence
Synchronous scanning fluorescence spectroscopy, SSF, is a simple, cost effective method for the fingerprint analysis of many petroleum contaminates in groundwater and soil samples. The...
Identifying the Critical Path and Building Coalitions for Restoring Degraded Areas of the Great Lakes
Since 1985, eight Great Lakes States, the Province of Ontario, and the governments of Canada and the United States have led the development and implementation of remedial action plans...

Design-Build Goes Public
Public owners of civil works get paid to avoid risk. It's their job. Why try some experimental technique for building offices when safe, proven methods exist? But times have...
Aerogel?A Transparent, Porous Superinsulator
Silica aerogel is an unusual, transparent, low density, thermally insulating solid useful for a variety of applications. We have been investigating silica aerogel for use in transparent...
Implementation of Material Requirements in Specifications
This paper focuses on where to find information on materials, their compatibility, minimum standards and specifying of materials and their use. The paper also presents case histories on...
The Crown and the Curtain Wall
Crowning the complex curtainwall of an 870 ft concrete tower with a 150 ft high crown of aluminum masts in concentric rings above the 60th floor required ingenuity and extraordinary cooperation...
Minipile Milestone in Memphis
The maintenance/administration facility for Memphis, Tennessee's 300-bus fleet began displaying structural problems before it even opened for service in 1979. The 23 acre...
Engineering Pre-engineered Buildings
Pre-engineered buildings have become more sophisticated. There are several manuals and guides on how to engineer the so-called pre-engineered structures, but none are complete. There are...
The Mother of All Resilient Structures: Fixed-Base Tower in 3000-Foot Water and Some Outstanding Issues
This paper describes design and development work for 40- to 80-well fixed- base - yet compliant - towers for 2000- to 3000-foot water depths. Technical issues which are covered include:...
Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...
Measured to the Max
Engineers looking to model the behavior of a structure under seismic conditions often ignore the best source of data available: the building itself. Full-scale measurements of vibrations...
The Great Chicago Flood of 1992
In April of 1992, a breach in a freight tunnel caused the river that flows through Chicago to pour into city building basements, causing the city to shut down. Critical utility systems...
Perils of Point Loma
Rupture of the Point Loma sewage outfall in San Diego on Feb. 2, 1992, sent 180 mgd of primary-treated sewage coursing into shallow waters off the city's coastline. The article...
