Stability and Limit Loads of Steel Space Trusses
An investigation of the behavior of cold-formed steel space truss structures, under the interaction of local, member, and overall buckling is described. A Finite Element computer program...

Buckling of Thin-Walled Members by p-Version of FEM
P-Version of the finite element method (FEM) is used for one-D and three-D modeling of thin-walled open sections and axial compressive load. Equal angle and channel sections are used for...

Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...

Frame Stability
The Chapter on Frame Stability of the Fourth Edition of the SSRC Guide provides guidance on use of several stability design procedures. These include Critical Load Concept, Second-Order...

Dynamic Fracture Toughness of Rail Steels
As new premium alloy rail steels exhibit increased wear resistance and as track lubrication is used, the failure mode for rails is shifting from wear to fatigue. Elastodynamic finite element...

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...

Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...

GTRAF: The Netsim Graphics System
This paper describes the development of an interactive computer graphics (ICG) system, named GTRAF, which will provide users with a new and highly efficient methodology for analyzing results...

Development of Graphics Displays for the Integrated Traffic Data System
This paper describes the development of interactive graphics displays for the Integrated Traffic Data System (ITDS) and provides technical details on the hardware and software considerations...

Highway Accident Collision Diagrams on a Microcomputer
Collision diagrams of highway accidents are schematic exhibits that illustrate the location of each accident with respect to the highway geometric features. The types of accidents; such...

A Model for Analyzing Large Transportation Networks on a Microcomputer
The Pedestrian Level of Service (PEDLS) model combines the best features of spreadsheet programs - their ease of use for inputting data and producing printed output reports - with the...

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...

Distributed Graphical Transit Scheduling System
The Graphical Scheduler is the latest of software products developed by SAGE for the transit industry. It was specifically designed to run on a micro-computer taking advantage of the latest...

Simulation of Intersections During Reconstruction
In order to make computer simulation of intersections more appealing and easier to use, and interactive, menu-driven micro-computer program, called INTERCON (Michalopoulos and Plum, 1986),...

A Simulation/Animation of an Inland Railway Container Terminal
The Container Terminal Model (CTM) comprises a batch computer simulation model and interactive graphics animation package. The model has been developed to aid engineers and transportation...

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...

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...

Strategic Human Resources Management
This paper discusses progressive human resources management strategies for improving the productivity and service performance of urban transportation organizations. The paper attributes...

Evolving Strategic Management Processes at State and Regional Transportation Agencies
Recent progress and accomplishments in strategic planning/management at four transportation agencies: the Pennsylvania Department of Transportation, New Jersey Transit Corporation, New...
