Substitute Wind Concept for Elastic Stability of Cooling Tower Shells
The influence of the nonaxisymmetric wind distribution on the stability behavior of cooling tower shells is examined. It is demonstrated, considering about 50 cooling tower shells, that...
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....
Application of a Hybrid Strategy for Structural System Reliability Analysis
The authors have attempted to explain a strategy for structural systems reliability calculations. In essence, it involves the use of different methods at appropriate times in the search...
Reinforced Concrete Column Reliability
A method is proposed whereby the reliability is obtained using the stable configuration approach of structural system reliability. The configurations are defined based on imposed strains...
Reliability of Structural Systems With Multiple Limit States
The purpose of this paper is to present a systematic treatment of the reliability of structural systems with multiple limit states. Several performance criteria (e. g. , excessive deflection,...
Fishing the Four-Lane
Recent changes in one Montana canyon have shown that even highways and freshwater fish can happily coexist with the proper planning. Twenty years ago, the Montana Department of Highways...
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...
A Microcomputer Storm Sewer Program for Highway Drainage Design
This paper presents results and findings of an ongoing research project on highway drainage sponsored by the Federal Highway Administration through the Virginia Transportation Research...
Highway Statistics Summary on Microcomputers
Oak Ridge National Laboratory (ORNL) is under an interagency agreement with the Federal Highway Administration, Department of Transportation, to prepare the necessary historical highway...
Materials and Member Behavior
Each of the papers in this book covers some aspect of material properties. New developments in cold formed steel are reviewed. The strength, stiffness, and ductility of steel connections...
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...
Dynamics of Structures
This volume includes the papers presented at the 6th Structures Congress of ASCE which deal with the analysis, design, and behavior of civil engineering structures and facilities subjected...
Harbor Revived
In Racine, Wis., officials' plans to turn a defunct commercial harbor into a recreational boaters' paradise have signaled an economic turn-around for a depressed...
Tunnel Saved by Flyash
When inspection early in 1986 showed that Detroit's Northeast Raw Water Tunnel was near collapse at one location, quick action and a unique use of flyash-cement grout or fill...
