Analysis and Full-Scale Testing of an Aircraft Shelter
Abstract
The objective of this research was to determine the response of a semicircular orthotropic steel shell aircraft shelter when subjected to symmetric and unsymmetric static load conditions. A numerical technique is presented which is capable of treating the problems of nonlinear material properties, nonlinear geometry, flexure and axial compression, and the orthotropic nature of the structure. Basically, a mathematical model is developed which exhibits the same characteristics (moment-rotation, load- deformation, and ultimate strength) as a finite portion of the actual structure. This information is then used as input to a digital computer program for proper assembly of the stiffness coefficients and subsequent solution. The method of analysis is based on a differential approach to the basic displacement method, and a fourth-order Runge-Kutta integration technique is employed to integrate the differential equations. To verify the analysis, 22 tests were conducted on a full-scale structure which compared favorably to the numerical analysis.
