Abstract:

The details of a study to experimentally measure the stresses induced in a portable rigid wall shelter by loadings typical of the transportation environment are documented. In the transportation configuration the shelter measures 6.1 m long x 2.4 m wide x 2.4 m high 20 ft x 8 ft x 8 ft and is designed to the requirements of the International Organization for Standardization ISO. In the deployed configuration the width expands to 6.4 m. The primary construction material is an aluminum faced paper honeycomb core sandwich panel. The shelter was instrumented with accelerometers and strain gages and subjected to loadings typical of the ISO and military transportation environment. The strain and acceleration data generated during the tests and details of several structural failures are presented. Author
