Analysis of Stresses and Deflections in Frame Supported Tents

Abstract

A finite element computer code has been developed for predicting the stress and deflection in frame-supported tents under static load. The code can accept geometric nonlinearities due to large deflections and nonlinear biaxial stress/strain fabric properties. The predictions of the computer code are validated by tests performed on two 1/8-scale model tents that approximately model two existing Army tents, the tent maintenance shelter and the Fritche shelter. The 2.6-oz cotton typewriter ribbon cloth used in the models was tested on a biaxial testing machine to obtain its biaxial stress/strain behavior for input to the computer code.
