Total Optimization of Truss Considering Shape, Material and Sizing Variables
A total optimum design method is developed for truss structures in which the shape of the structure, discrete material kinds and cross-sectional areas of member elements are optimized...

Plates and Shells with Crack-Like Flaws
The formulation of new hierarchial finite elements for the analysis of laminated plates and shells in the presence of flaws are discussed. The performance of the elements is evaluated...

p-Version of FEM and Shape Optimal Design
This paper presents some research results obtained recently in using the p-version of the finite element method (FEM) for shape optimal design. It is shown that the p-version 2-D elastic...

Buckling of Tapered Columns by P-Version of F.E.M.
The local, distortional, overall, and interactive buckling of tapered, thin-walled members under axial compression and flexure are considered by using three-dimensional models based on...

An Object-Oriented Model for Building Design and Construction
This paper describes the initial work done in developing a modelling environment which captures both functional and spatial aspects of a building, abstract and detailed descriptions, and...

Discrete Optimization of 3D Steel Frames
The purpose of this paper is to report the results of the application of a general discrete optimization procedure to the design of a realistic, three-dimensional steel building frame....

Vector Optimization of Structural Systems
In this paper the basic ideas of vector optimization are presented, and both the weighting and constraint methods are applied to vector optimization of truss systems by minimizing the...
