Stress Computations for Nearly Incompressible Materials
Computation of stresses by the finite element method (FEM) in the case of nearly incompressible isotropic elastic materials is discussed. It is shown that for moderately high Poisson's...

Experience with the p-Version Program PROBE
The conventional approach in the FEM is known as the h-version, in which the solution accuracy depends on the size h of elements. The alternative approach is the p-version, in which the...

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...

Some Interactive Graphics and Parallel Processing for Earthquake Engineering
Ongoing research at Cornell University on computer-aided earthquake engineering of building structures is exploiting innovations in computing in several areas. Although some of the approaches...

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...

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...
