Domesticating Steel
Residential contractors, nervous about fluctuations in lumber prices and quality, would welcome steel framing into the housing market if the necessary infrastructure were in place. Despite...
Balancing Act
The cable-stayed $69 million Glebe Island Bridge in Sydney was built using a combination of one rolling frame and one form traveler instead of a more orthodox two or four form traveler...
Framing a Work of Art
One of the most visually unique building designs of the twentieth century, the Guggenheim Museum project in Bilbao, Spain, required an innovative structural engineering solution and pioneering...
Concrete Colossus
After finding 120 million cubic meters of oil and 30 billion standard cubic meters of natural gas 175 kilometers off the Norwegian coast, Houston-based Conoco, Inc. was faced with a second...
A Dual Answer to Seismic Stress (Available only in the Structural Engineering Special Issue)
Are two systems better than one? When it comes to high-rise seismic design post-Northridge, the answer may be yes, based on studies conducted by CBM Engineers, Inc., Houston. The aftermath...
Advances in Structural Optimization
A compilation of twenty papers,
Braced for Failure (Available only in Structural Engineering Special Issue)
Investigations into the collapse of steel-framed structures often focus on minor, insignificant design flaws, only to ignore the real culprit: inadequate temporary bracing. The collapse...
Guidelines for the Design of Double-Layer Grids
Prepared by the Task Committee on Double-Layer Grids of the Committee on Special Structures of the Structural Engineering Institute of ASCE. This report...
Dampers Do the Job at Davis (Available only in Structural Engineering Special Issue)
Three recent earthquakes�the Kobe earthquake in Japan and the Loma Prieta and Northridge earthquakes in California�have caused engineers to take a much more serious approach to seismic...
Forensic Engineering
This proceedings contains the papers resented at the First Forensic Engineering Congress, a special part of the American Society of Civil Engineers Annual Convention held in Minneapolis,...
Comparison of Blast and Earthquake Effects on Reinforced Concrete Frame Structures
This chapter compares the damage done by an explosive blast and an earthquake....
Evaluating Earthquake Hazards
Earthquake hazards vary considerably in different parts of the country. The effect of an earthquake on telecommunication systems is influenced by the magnitude of the earthquake, the proximity...
Guyed Structures Configurations
This section considers guyed structure configurations, such as single poles or masts, stub poles, H-frames, rigid frames, and masted towers....
Analysis
This section presents theoretical and practical concepts for the analysis of guyed transmission structures. The concepts are further illustrated in the examples of Section 8. The term...
Design
This chapter discusses guyed structure design. Topics include loadings and design restrictions; guy clearances; guy design; guy anchorage; connections; structural design of poles and H-frames;...
Seismic Solutions for Steel Frame Buildings
After the Northridge Earthquake, damage in steel moment resisting frame connections stunned engineers. Now those engineers are scrambling to find and test new kinds of connections. This...
Spotlight on Steel Moment Frames
Engineers' confidence in moment connections was shattered when damage was discovered after the 1994 Northridge earthquake. Such connections are now a hot subject for U.S....
Project Control
The project work plan, as originally written and modified during the course of projects, sets up specific schedule and budget yardsticks; each project task is to be completed in a specific...
The Northridge Fractures: Are We Learning the Right Lessons?
After the Northridge earthquake in January 1994, engineers found problems with special moment-resisting frames. There were multiple facture modes, and typical damage involved primary crack...
Northridge Postscript: Lesson on Steel Connections
Immediately after the Northridge earthquake in January 1994, the general concensus was that steel-framed buildings performed extremely well. Later, inspectors were surprised to find weld...
