Design practice of the preloading method, which is one of the ground improvement techniques, applied for the hydraulic fill area includes quite complicated problems, especially when draining...

Integrating Qualitative and Quantitative Reasoning in Structural Engineering
Qualitative reasoning has applications in engineering problem solving and the development of intelligent computer-aided engineering tools. Most applications in structural engineering have...

Deriving Alternative Structural Modifications Based on Qualitative Interpretation at the Conceptual Design Stage
Current computer tools provide little support in deriving alternative modifications based on qualitative structural interpretation of a conceptual design. This paper presents a behavior-based...

Implementing Qualitative Reasoning for Structural Design Using Constraint Propagation
All designs begin with qualitative reasoning and therefore, this activity has an important influence upon subsequent quantitative stages. In structural design, qualitative reasoning starts...

Reducing Ambiguity in Qualitative Reasoning
Qualitative reasoning derives the behavior of a physical system using a representation of the fundamental principles for the domain. In qualitative reasoning parameters are mapped into...

Integrated Slab Design Automation System Using Knowledge-based Approach
There has been a strong trend towards the integration of computer aided design and engineering during recent years. But all the systems can not provide the completely integrated functions,...

Interference Detection with 3-D Computer Models
Interferences between building components during construction is an inherent byproduct of multiple disciplines designing their components separately. Manual solution techniques for detecting...

Three-Dimensional FEM Analysis with Graphical Interface
We have developed a Three-Dimensional FEM Program with an extended graphical interface aimed at analyzing buildings. This program is linked with our CAD system, which can easily produce...

Editing Existing Paper Drawings
