Superquadric Object Representation for Dynamics of Multi-Body Structures
While the finite element representation of an object in terms of nodal coordinates and shape functions is ideal for representing the stress and energy state, it is not well suited to the...

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....

Optimizing the Design of High-Rise Steel Buildings
The approximate stiffness method is utilized for a proposed procedure to evaluate the stiffness of the various frames and the stiffness of the members within the frames to provide a drift-controlled...

Optimal Design of Tall RC Tube Buildings
The analysis and design of reinforced concrete framed tube buildings is formulated as a nonlinear optimization problem and solved using modern design optimization software. The influence...

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...

Optimization of Structures Subjected to Vibrations
A minimum cost optimization procedure is presented for the analysis of multi-degree freedom structures subjected to steady, transient and random vibration environment. The procedure is...

Methodology in ODSEWS-2D-II for Optimum Design of Structures to Seismic and Wind Forces
