The Ultimate Load Design Method of R/C and P/C Shell
Based on the testing results of 20 full size shells and models, the ultimate load analysis method is proposed to design four different kinds of reinforced concrete shallow shell structures....
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....
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,...
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...
Highway Safety Analysis and Monitoring
The Highway Safety Analysis and Monitoring (HISAM) software was developed under a Federal Highway Administration research contract and is designed to aid local agencies with data base...
Transportation Network Building Using a CAD Interface
This paper illustrates how Barton-Aschman Associates, Inc, has made use of AutoCAD(TRADEMARK) on the microcomputer to digitize an existing highway network and to create a new network from...
NEDS?Network Editing and Display for TRANPLAN
This paper explores some of the current and possible future applications of interactive graphics packages to the tasks of analyzing and planning transportation systems. The source of the...
Applications of the General Network Editor
The General Network Editor is a graphical, data base manager for computer-aided design of transportation networks. Its principal use is for entering network data into the computer: drawing...
County-Level Planning Model in Atlanta Region
Gwinnett County is working with the Atlanta Regional Commission (ARC) and Barton-Ashman Associates to download the ARC trip tables for use in a microcomputer transportation planning model...
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...
Roadway Geometric Design Applications
'Road Design, Version 2. 0,' an improved version of the original introduced at the National Conference on Microcomputers in Urban Transportation in San Diego...
Microcomputer Applications for Pavements
The Federal Highway Administration (FHWA) has been active in exploring expanded microcomputer applications with the goal of improving efficiency and benefits to the public through reducing...
Automated Pavement Management Systems for Agencies
