Applied P-Delta Methods in the Design Office
At first glance some axioms of a P-Delta analysis appear to be paradoxical. First, the P-Delta effects are a direct function of the depth of the structure parallel to the wind direction....
Practical Application of PR Connections and Second Order Analysis
In the present LRFD Specifications type PR (Partially Restrained) connections are described as those where the connections of beams and girders possess an insufficient rigidity to hold...
Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...
Second Order Analysis of a 47-Story Building
A modern day second order analysis and ultimate strength review is made of a hypothetical 47-story unbraced frame designed under the 1969 AISC Specification. The original design is part...
Tall Building Stability -- Practical Considerations
Simple techniques for including lateral stability effects in the design of tall buildings are proposed. The application of these techniques in the design of a 66-story building is described....
Frame Stability - A Canadian Designer's Approach
The deficiencies and fallacies of the simplistic effective column length approach to frame stability are demonstrated through its application to a 57-story rigidly framed building structure....
Dioxin and Resource Recovery
The 1987 ASCE Dioxin and Resource Recovery Symposium was held at the New York Hilton Hotel, New York on February 10, 1987. The conference served as an opportunity to assess the issue of...
Building High Tech in China
The tallest steel structure in the People's Republic of China is being built by an international complement of designers, suppliers, vendors and contractors. It is the 42...
Treating Expansive Soils
Damage that expansive soils do to light buildings can often be prevented or mitigated by preconstruction soil treatment. Treatments of three kinds are described�reworking the soil, controlling...
Activity Center Development Impact Analysis
A flexible microcomputer spreadsheet analysis method is described for analyzing area-wide and localized impacts of new development in urban or suburban activity centers. The analysis approach...
Computerization of Transit Performance Evaluatio
The Virginia Transit Performance Evaluation Package (VATPEP) has reduced the state's effort in processing information for its annual report on public transportation from over...
Running Rucus II on a Microcomputer
Since the preliminary version of the RUCUS II (Run Cutting and Scheduling System) was released by UMTA in 1982, the system has achieved considerable acceptance by transit properties. These...
Using Microcomputers for Maintenance Management in a Small Transit Agency
The Wisconsin Department of Transportation, (WISDOT) Bureau of Transit asked a small transit agency to join an UMTA funded project that would perform a needs assessment, locate or develop...
Cost-Effective Sizing of the Transit Extraboard
In 1983, the Urban Mass Transportation Administration (UMTA) provided funds to develop manual procedures known as the User's Guide to Optimizing the Transit Operator Work...
Building Structures
This volume contains over forty papers from thirteen sessions of Structures Congress '87. The papers include a variety of topics on the overall behavior and design of buildings...
Computer Applications in Structural Engineering
The papers in this book deal with the development or application of software systems to the design, analysis, and drafting activities associated with engineered structures. A number of...
Save the Walls
A rehabilitation job in name only, the 75 year old Army and Navy Club, a landmark located in Washington D.C.'s Golden Triangle, retained only two of its 80 ft high exterior...
Concrete Strength Record Jumps 36%
A Seattle building now going up has 19,000 psi concrete, the strongest ever in conventional structures. It costs three times as much as conventional concrete, so will not be widely used....
Can Urban Transportation Be Managed as a Business?
There are many managerial tools and techniques available to the transportation professional that have been tested, tried and perfected in the private sector, and in a limited way in the...
The Business of Urban Mass Transportation
