This thesis is concerned with the use and development of mass matrices. A literature study is performed to determine the role of the mass matrix in the current state of the art of dynamic structural analysis. For simplicity ...

This study compares energy minimization with direct stiffness for linear structural analysis. The energy minimization approach locates the generalized displacement vector by minimizing the total potential energy of the ...

One of the most critical urban problems is the ever-increasing demand for transportation facilities. An alternative for reducing the degree of peak-hour congestion is to increase the passenger movement capability of a ...

An objective function that is suitable for both stable and unstable equilibrium states since it is guaranteed to assume a relative minimum at any equilibrium state is presented. The objective function, which is the inner ...

An experimental and finite element investigation of the behavior of single-span, simply-supported folded plate structures containing rectangular openings is summarized. A seven-plate aluminum model was tested under a ...

The primary purpose of this thesis is to investigate stability boundaries, or load interaction curves, of a reticulated dome. An elastic, geometrically nonlinear model with 21 degrees of freedom is considered. The nonlinear ...

The results obtained from the nonlinearly elastic, geometrically linear beam-column are almost identical to the results obtained by the method of Gurfinkel and Robinson [6] within the linear range of the stress-strain ...

A numerical solution technique was developed to solve the one-dimensional, partial differential equations of unsteady flow for an upstream solution. The x-t, distance-time, plane was replaced by a rectangular grid of points ...

It is the intent of this paper to investigate how the convergence rate of a fully stressed design method using a stress-ratio algorithm may be affected by manipulating various parameters. The parameters studied are: (1) ...
