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...

Selecting Precast Concrete Building Systems
The development of an integrated computer system to assist in the selection of precast concrete (PC) building systems is described. StructNet, a neural network program, identifies possible...

Selection of Earth Retention Systems Using Expert System
The development of the selection module in a knowledge-based expert system REtaining STructure EXpert (RESTEX) for automated selection, design and analysis of earth retention systems is...

Quality Management of Earthwork Using Knowledge-based Systems
Earthwork is an integral part of many construction projects. It involves cleaning of the site, loading and spreading of soil, and soil compaction and leveling. Heterogeneous orientation...

Scaling Up is Hard to Do: Experiences in Preparing a Case-Based Design Aid Prototype for Field Trial
We seek to improve the conceptual design process for complex artifacts such as buildings by offering designers access, through an on-line hypermedia library, to documentation and evaluations...

Case-Based Design in the SEED System
We present the requirements for case-based design in a software environment to support the early phases in building design and outline an approach to satisfy them. We briefly discuss implementation...

FEM in a Design Code Environment
The results obtained from the use of finite element based analysis tools have created a new problem for designer: Which numbers do we use to check against Code limits? Most of the commonly...
