An Analysis Of The Behavior Of Steel Liner Anchorages, Daryl R. Armentrout

Doctoral Dissertations

The purpose of this study was to analyze the load-deflection behavior of liner anchorage systems used in the design and construction of steel-lined concrete containment structures in nuclear power plants. Both and angle, 3 x 3 x 1/4 inch, and structural tee, WT 4X7.5, embedded in concrete were analyzed using two dimensional plane stress finite element models. Specifically the PAFEC 75 computer program with its bilinear stress-strain capability was used. The intent of this investigation was to produce analytically similar results to those measured in anchorage tests conducted by The University of Tennessee, Knoxville.

These tests produced curves of the …

The Development, Implementation, And Evaluation Of Depletion Perturbation Theory In A Light Water Reactor Nodal Code, Stephen M. Bowman

Masters Theses

A generalized depletion perturbation (DPT) theory formulation for light water reactor (LWR) depletion problems is developed and implemented into the three-dimensional LWR nodal code SIMULATE. This development applies the principles of the original derivation by M. L. Williams to the nodal equations solved by SIMULATE. The present formulation is first described in detail, and the nodal coupling methodology in SIMULATE is used to determine partial derivatives of the coupling coefficients. The modifications to the original code and the new DPT options available to the user are discussed. Finally, the accuracy and the applicability of the new DPT capability to LWR …

A General Solution For Wind Tunnel Boundary-Induced Interference In Two-Dimensional Subsonic Flow, Werner Johann Anton Dahm

Masters Theses

A general solution is presented for determination of wind tunnel boundary-induced interference in two-dimensional subsonic flow. The solution requires no a priori knowledge of the model geometry or tunnel wall characteristics, and instead, relates the interference to velocity measurements at a selected control surface within the tunnel. The solutions for the tunnel, free-air and interference fields are obtained using linearized subsonic theory with the Fourier transform technique. An analytical example dealing with the case of the wavy wall in the presence of a generalized tunnel wall boundary condition demonstrates the validity of the solutions in closed form. Numerical examples dealing …
