Dynamic Response of Tall Buildings to Wind Loads
The purpose of this study is to perform a probabilistic analysis of tall buildings subjected to wind excitation. A time domain simulation is first applied to the nonlinear problem. After...
Resolving Reliability Issues for an Offshore Platform Code
A fixed steel offshore platform design specification based on reliability concepts has been developed which could become an alternate to the existing working stress code, American Petroleum...
Steel Pipe Foundations for Deep Water
Four innovations are helping to make steel pipe piles more popular for foundations in deep water in Southeast Asia. Until recently steel was usually rejected for these applications, because...

Cables in Trouble
Having inspected more than half of the world's cable stayed bridges, the authors conclude that many are in danger of sudden collapse unless corrosion problems can be stopped....
Design/Construct Contract Speeds Bridge Job
In the name of time and money savings, Pennsylvania DOT is building a bridge using a modified turnkey contract. In contrast, the standard approach is first to design the bridge, then ask...
Rehabbing the Underground Railroad
The Park Ave. Railroad Tunnel brings three commuter rail lines into New York City's Grand Central Station. The four tracks occupy three tubes from 97th St. to 57th St., where...
Cable Stayed Bridges
Two of these five papers on cable-stayed bridges deal with wind analysis. One develops the theory for motion due to flutter and reaches the conclusion that the vibrations are, in general,...
Kissimmee River: Engineering Approaches for Restoration
The Kissimmee River, located in central Florida, was channelized for flood control during the 1960s. Movements by environmental interest groups have produced strong sentiment to restore...
Composite Construction in Steel and Concrete
Composite steel-concrete systems are used extensively for buildings, bridges, and other civil engineering structures. Research and development related to composite construction are in...
Guide for Design of Steel Transmission Towers

Tied Arch Substitute
When the Minnesota DOT decided to build a new bridge to replace St. Paul's historic High Bridge over the Mississippi, a citizen's advisory group insisted that...
Weathering Steel: Industry's Stepchild
Improper location and poor detailing are two reasons why some weathering steel bridges are not living up to their early promise. That was the consensus reached during a July 1988 forum...
A Safe Skyscraper For the Seismic City
When completed in late 1989, the 73-story First International World Center will be the tallest office building in Los Angeles. The steel structure of the building was designed to be ductile...
