Brooklyn Bridge
To commemorate the 100th anniversary of opening of New York City's Brooklyn Bridge in 1883, the Smithsonian Institute has mounted, and opened to the public in the anniversary...
The Quiet Revolution in Skyscraper Design
Since the 1960's, there has been a major change in the philosophy for designing high-rise buildings. Up to that time, most buildings were designed to resist wind forces by...
Geotechnical Practice in Offshore Engineering
The offshore industry as it exists today is just 30 years old. In that period the depth of water where structures are built has increased from a few feet to over 1000 feet. The performance...
Behavior of Metal Structures
This technical symposium illustrates the various aspects of transfer of information from research results to engineering practice. The papers cover historical technical background, current...
West Coast High-Rise Condo Opts for Ductile Concrete Frame
In the past, the vast majority of high-rise buildings constructed in earthquake prone areas of the West Coast have employed a steel frame. However, recent advances have made it feasible...
Innovations Cut Costs of a Power Plant's Water System
A two-unit (660 MW each) coal-fired power plant in St. Clair, MI, requires 660,000 gallons of water for condenser cooling. A once through cooling system from the St. Clair River (one mile...
Steel Beats Concrete for Idaho Bridge
As an alternative to prestressed concrete design, the State of Idaho and the Federal Highway Administration encouraged the use of cable-stressed steel girder design for the Bonners Ferry...
Design of Prefabricated Offshore Structures for Ice Forces
The design of fixed offshore structures to resist forces from sea ice features is reviewed. The emphasis is on prefabricated structures constructed elsewhere, towed to location and installed,...
Structural Steel Details: Is Responsibility a Problem?
Because structural engineers are leaving design of structural steel connections to fabricators, the problem of responsibility for those details has arisen. This article explores a variety...
Rehabbing Historic Buildings
Historic buildings often require structural upgrading before the cosmetics of restoration can be applied. Two case studies are presented here. The Four Seasons Hotel in Seattle required...
Frame Program
A plane frame program for structural analysis that is short to program and easy to understand is presented. Included inl article is a complete print-out of the program with a step-by-step...
Oil Rigs Designed to Combat Arctic Ice
Exploration and drilling rigs now being designed for use in the Beaufort Sea must withstand ice forces never before encountered. Design approaches include using the geometry of these structures...
Structural Analysis of Light-Frame Subassemblies
Conventional light-frame subassemblies have a long history of good performance. Until recently this performance could not be quantified adequately because of the complex ways in which...
Structural Analysis of Light-Frame Wood Buildings
This paper reviews the information currently available and lacking that is needed for improving design procedures. Some initial attempts at theoretical analysis of entire wood buildings...
Grouting in Geotechnical Engineering
The 63 pages included in these proceedings came from 12 different countries and deal with the pertinent advances in grouting materials and technology that have occurred throughout the...
World's Largest Installation of Fabric-Formed Pile Jackets
One major feature of fabric forming is permeability. One application of this technique is protective encasement of steel H and pipe piles at a major pier in Chile. The Huachipato Pier...
Engineer's Notebook: One-step Formula for R/C Tension Steel
In the design of reinforced concrete beams, after loadings and materials are defined, the first step is to assume a beam depth. Then the required steel area and beam width are determined....
Causes and Preventions of Lamellar Tearing: Engineer's Notebook
Within the past 10 years, a steel cracking problem, lamellar tearing, has arisen after welding of thicker sections and higher-strength steels. A separation underlying a weld joining plate...
Steel Cable-Stayed Bridges: Can They Compete in the U.S.?
During the past decade, concrete bridge designs have been winning more bids for contracts than steel cable-stayed bridges. Reasons for this trend are examined. A brief evolution of bridge...
Trouble Shooting ChemicaLly Resistant Masonry
This paper is a series of case histories showing specifically how lack of understanding of the nature of the materials and their proper uses has caused failure in design, specification,...
