Knowledge Bases for Multistory Concrete Buildings
Heuristics are used in the concrete building industry. A knowledge base is developed with heuristics used in the selection of the floor framing system of a concrete building....

Expert System Integrity Maintenance for the Retrieval of Data From Engineering Databases
This paper describes a mechanism that enables one to automatically monitor and evaluate engineering design data retrieval. It presents a framework, associated with a relational database...

A Knowledge Based Technique for Structural Component Design Programs
Traditionally, computer programs written for the purpose of sizing and checking standards compliance of individual structural members have been authored in high level compiled languages...

Computer Errors?Who's Responsible
This paper proposes that both the program developer and the program user share the responsibility for preventing errors in the use of computer programs for engineering design and analysis....

The Engineering Workstation at Skidmore, Owings & Merrill
The computer group at Skidmore, Owings & Merrill has developed a unique workstation environment which aids both the generation of information in the design phase, as well as the...

Computers in Structural Engineering Practice The Issue of Quality
The dilemma of affordable and easy access to computing versus uncertain and dangerous pitfalls will be a continuing one for the profession. Since the pitfalls include problems associate...

How Do I Find the Information I Needed Yesterday?
One reason that the professional has not been more effective in learning from failures is that the information disseminated has not always reached the right people. The Architecture and...

A Power Planning Model for Seismic Risk Zones
We present a model to configure a nuclear power system consisting of plants and the distribution network. In the model, we quantify seismic risk as comprehensively as possible in terms...

The Charles River Project
The Charles River Project received the 1984 Presidential Award for Design Excellence in Architecture, Engineering, and Urban Planning. Sited between Charlestown and Boston's...

Solving Complex Urban Design Problems
Waterfront redevelopment projects under construction today should be a designer's dream. They offer an opportunity to apply a unified, large-scale vision to unusually large...

Design and Effectiveness of Urban Retention Basins
Retention basins are recommended by practicing engineers and regulatory agencies for stormwater management in new land developments. They may require considerable space which limits their...

Techniques for Rapid Assessment of Seismic Vulnerability
Under the impetus of a growing awareness of seismic hazards, there is an increasing effort being devoted to assessing the seismic vulnerability of existing buildings. For many professionals...

Modeling Human Error in Structural Design and Construction
Human error is recognized as the major cause of structural failure. Moreover, it may greatly exacerbate the damaging effect of other hazards, such as earthquakes. The objectives of this...

Stability Under Seismic Loading
This publication includes five papers that cover the p- ? effect on seismic structures with semi-rigid connections, the effect of panel zone deformations on the structural response behavior,...

Recent Developments in Structural Optimization
This publication contains seven papers that emphasize the recent findings of mathematical formulations, numerical results, and algorithms in structural optimization. Among them, two deal...

Bridging the Joints in Bridges
Most bridges are designed with gaps in them. The cracks allow bridges to expand and contract as the temperature changes. But water can enter these gaps and foul bearings and structural...

Building on Water
During the last century, innovations in concrete have paved the way for the evolution of marine concrete structures. Oakland's proposed Carnation Container Terminal is using...

Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...

Designing for Shock Resistance
If a product or structure is subject to shock loadings, and is unable to take them without unacceptable damage, it must be insulated from the shock. The decision may be to redesign the...

Spreadsheets: A New Design Tool
New techniques are developing which make computer programming easier. One new technique is spreadsheet programming for microcomputers. Two programs are presented which give a quick overall...
