Success Syndrome: The Collapse of the Dee Bridge
Scaling up existing successful designs can cause latent weaknesses to become dominant, leading to catastrophe. By studying past failures where this has happened--for example, the 1847...
Locking Into Success
In 1961, at Wheeler Lock in Alabama, crews with the Tennessee Valley Authority tried to incorporate an existing lock wall into a new cofferdam. A major portion of the land wall slid about...
Road to Recovery
The effect of the Loma Prieta earthquake on San Francisco's elevated viaduct system is still being felt more than four years later. Immediately after the quake, the entire...
Coastal Groins and Nearshore Breakwaters
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers No. 6. This book provides guidance for the design and placement...

Modular Evolution
The construction industry typically thinks of modular steel bridges in terms of the World War II vintage Bailey Bridge. The Bailey Bridge was designed to be quickly deployed to replace...
Solar Stretch
Extrapolating from structural work with textile or metal membrane roofs to cover silos, assembly halls and sports stadia, Schlaich, Bergermann and Partners, a structural engineering firm...
Functional Analysis of the Envelope Design Process for Integrated Building Design
Building envelope failures account for a great portion of building failures. The number of envelope deficiencies would be reduced if the design process was integrated. Integration would...
The Context?Oriented Model: An improved Modeling Approach for Representing and Processing Design Standards
Current electronic design evaluators employ one of three primary computational models to represent a design standard: the Condition/Consequent, Object-Oriented and hybrid models. The problems...
Object-Oriented Structural Analysis with Substructures
Computer-aided structural analysis is a mature field. However, recent research has produced advances in the areas of automated modeling, multi-processing, and programming techniques. The...
An Object-Oriented Approach for Reinforced Concrete Design
The use of the object-oriented programming approach in developing applications for the analysis and design of reinforced concrete members is discussed. Two object oriented programming...
Concurrent E-I Algorithm in Structural Dynamics
A concurrent explicit-implicit algorithm for time integration of the differential equations arising from a finite element discretization is described. The first step of the method consists...
Nonlinear Analysis of Structural Frameworks Using Supercomputing Techniques
Applications of vectorization and the parallel processing technique of multitasking in the elastic nonlinear analysis of building frameworks are presented. The proposed algorithm is implemented...
Representing Design Cases Based on Methods
This paper discusses an approach to representing design cases using the methods used in solving specific design problems. This differs from the conventional representation of design cases...
Representation of Case Memory for Structural Design
One of the major issues to be addressed in the application of case-based reasoning to structural design is the representation of design projects in case memory. The content of the information...
Advances and Challenges in Case Based Design
The application of the case-based design (CBD) method to preliminary building design provides an opportunity to overcome problems associated with traditional computer-based design methods....
Modeling to Generate Alternatives in Discrete Structural Optimization
Structural design, like other complex decision problems, involves many trade-offs among competing criteria. While mathematical programming models are increasingly realistic, there are...
Multicriteria Optimization in Engineering Design
An engineering design optimization problem can be formulated as a search of the solution space for which the relationships among various groups of attributes are given. The search can...
Representation of Vertical Constraints Knowledge for Scheduling Multi-Story Projects
Multi-story projects are characterized by many repetitive units or typical floors that involve identical activities repeated consecutively from one floor to the next. Horizontal logic...
