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...
A Simulation of the Quake-response on the Frame with Large Basement-box under the Earthquake from Deep Soil Layer
This paper treats a study of computing vibratory analysis and its comparison with measurements for the earthquake-responses on an actual 19 storied pure frame-structure with its height...
Nonlinear Earthquake Response Analysis with Partial Uplift of a Building on a 3D Layered Half-Space Using Dynamic Stiffness in Frequency Domain
Buildings...
Editing Existing Paper Drawings
In the last five years, developments in creating and managing engineering drawings completely, within a computer environment, have been phenomenal. Computer Aided Design continues to make...
Modular Software for Editing Paper Drawings
Revising, tracking and storing large format engineering drawings has always been an expensive and complex problem for large industries. The management problem became much more complex...
Maintaining Engineering Drawings in the '90s
With the technologies available today, it is possible to begin a scanning system at a rather small or limited scale - and still realize a quantifiable return on investment. In the 90's,...
Your Paper Drawings in the World of Organized Information
A comprehensive discussion of available hybrid raster-vector techniques and tools is provided. The author uses a sample project to clarify the most common misjudgements that result from...
A Comparison of Two AI Based Design Systems
Two applications of Civil Engineering based, AI systems are described. Although both systems are intended as design aids they have substantially different structures and methods of achieving...
Adapting Conceptual Clustering for Preliminary Structural Design
The use of conceptual clustering for knowledge acquisition can facilitate the development of a knowledge base in a domain where little formalized knowledge is really available. The limitations...
Neural Network Learning in Structural Engineering Applications
Neural networks based on the backpropagation learning algorithm have been used in a number of structural engineering applications. The paper classifies the different types of relationships...
Competitive Advantage of Using Computers in Structural Design
More and more structural analysis and design work is done using computers. The trend will continue because the software is becoming more powerful and the cost of computers is falling....
Computer Aided Experiments for Truss Structures
It is quite difficult to investigate structural mechanical properties by full scaled structure experiments. Consequently, an experiment using a reduced scale model is generally performed....
Linking CAD and Expert Systems for Constructibility Reasoning
This paper describes the prototype expert system COKE (Construction Knowledge Expert) that was recently developed at the Center for Integrated Facility Engineering (CIFE) at Stanford University....
Nonlinear Trial Load Method of Arch Dams
The trial load method is still an important method for the stress analysis of arch dams at present. However, the trial load method can be used only for the linear elastic analysis of arch...
Foundation Uniform Pressure and Soil Structure Interaction
The enclosed paper was presented in the ASCE, 8th Conference on Computing in Civil Engineering and published in its proceedings. One of its main assumptions was considering the foundation...
Creative Engineering Design Using Analogy
Designs in different domains vary in structure, performance and in many other aspects. However, their design purposes can be achieved in a limited number of ways. In this paper, we classify...
A Shape Annealing Approach to Creative Design of Structures
This paper shows how shape grammars can be used to model structural engineering problems. The shape annealing algorithm is then used to synthesize component topologies by bringing analysis...
Computer-Supported Creative Structural Design
In this paper, a model for creative engineering design using a network-based design prototype representation and a mutation technique is presented. The model distinguishes between a domain-dependent...
Optimal Adaptive and Predictive Control System of Buildings by Neural Network and Fuzzy Theory
This paper describes an optimal adaptive and predictive control system and its digital simulations for a single-degree-of-freedom system subjected to earthquake loading. In this system,...
