The mass matrix in dynamic structural analysis
(Virginia Polytechnic Institute and State University, 1978)
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 ...
Comparison of energy minimization with direct stiffness for linear structural analysis
(Virginia Polytechnic Institute and State University, 1979)
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 ...
An analysis of the Shirley Highway Express-Bus-on-Freeway Demonstration Project
(Virginia Polytechnic Institute and State University, 1972)
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 ...
Objective functions for nonlinear structural analysis
(Virginia Tech, 1978-07-05)
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 ...
A solution of the two parameter gamma model to relate unit hydrograph features to basin characteristics
(Virginia Tech, 1977-11-15)

Experimental and finite element analysis of a folded plate structure containing rectangular openings
(Virginia Polytechnic Institute and State University, 1970)
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 ...
Stability of a reticulated dome under multiple independent loads
(Virginia Polytechnic Institute and State University, 1978)
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 ...
Nonlinear analysis of plane frames
(Virginia Tech, 1975-05-05)
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 ...
Development of a reverse flood routing technique using the implicit method
(Virginia Polytechnic Institute and State University, 1972)
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 ...
Convergence characteristics of the fully stressed design method for plane frames
(Virginia Polytechnic Institute and State University, 1979)
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) ...
