Applying an Automated Storage and Retrieval System to a Centralized Bus Maintenance Facility
Gannett Fleming recently completed the design of a new Central Maintenance Facility for the Southern California Rapid Transit District. An integral part of this facility is an automated...

Advances in High Strength Concrete,
The technology for producing field placeable concrete with a 28 day compressive strength of 10,000 psi has been available for many years. With the recent use of microsilica as an additive...

The Transit Industry Microcomputer Exchange Support Center
The Transit Industry Microcomputer Exchange Support Center has been in existence for nearly three years. This paper describes the reasons for establishing the center, its current activities,...

Using QRS For Corridor Technology Assessment
This paper discusses the application of the Quick Response System (QRS) for testing the feasibility of light rail transit for a mid-sized city. The authors used data available from local...

Structural Design, Cementitious Products, and Case Histories
The papers in this book represent deverse topics in structural engineering. In design of beam-columns by the AISC interaction equations, it is demonstrated that an inadequacy exists when...

Tunneling a Bridge
Linking an addition to the Georgia World Congress Center in Atlanta required a pedestrian tunnel through a railroad embankment 100 ft wide and 40 ft high, with no disruption of train service...

Rail Planning�Texas Style
The Dallas Area Rapid Transit (DART) Authority has a 25 year plan to build a 147 mile rail network�all without federal funds. When DART hits its 2010 target date for completing the rail...

Abstracts
Abstract only. The abstracts are presented of the papers presented at the 16 Sessions of the Conference, Transportation 85. The papers relate to the following session topics: CAD (ADS,...

Structures Congress Honors Fazlur Khan
Speakers at a session of the 1983 ASCE Structures Congress paid tribute to the late Fazlur R. Kahn by describing his work in developing structural systems for highrise buildings that were...

Establishing Patterns of Building Failures
Establishing statistical patterns of building failures can help engineers and architects prevent similar failures in the future and also reduce litigation. The Architecture and Engineering...

Peer Review: A Management Tool for Public Sector Projects
If done correctly, peer review can be an effective tool in managing public sector projects by reducing costs through careful weighing of design alternatives by experts in the field. The...

Curved Sewers: Yes or No?
A study of curved sewer use in Southern California examines sewer design and maintenance of curved versus straight sewers. A telephone survey of personnel in design and maintenance of...

Rail and Road Traffic Continue During Bridge Modification
The crossing of Route 15 under the Bangor and Aroostook Railroad Bridge, Bangor, Maine had limited sight distance and marginal clearances. Maine Department of Transportation, therefore,...

Trends in Small Computer Utilization
In an effort to determine the extent to which micro and minicomputers have been successfully implemented by construction contractors, the authors compiled a comprehensive questionnaire...

High Rise Design: Accounting for Column Length Changes
In the late 1950's and early 1960's, the height of concrete buildings jumped from 20 to 60 stories. During the same period, architects introduced the use of exposed...

Seismic Design for Sacramento Light Rail Transit System
The Sacramento Light Rail Transit Project is an 18. 5 mile system which provides the trunk line service for an integrated Bus/LRT public transportation system. Seismic design utilized...

Seismic Design of Underground Structures Southern California Metro Rail Project
The effect of earthquakes on underground structures is the imposition of an arbitrary deformation which cannot be changed by strengthening the structure. The structural design goal is...

Coupled Vertical-Rocking Response of Base-Isolated Structures
A base-isolated building can have a small horizontal eccentricity between the center of mass of the superstructure and the center of rigidity of the supporting bearings. The structure...

Planning of CAE and CADD Centers
