Structural Analysis of the Two-Side Expandable ISO Shelter: A Floor Vibrations Mitigation Study

摘要

The TwoSide Expandable ISO S-786 Shelter is a tactical shelter fitted for 100-A electrical service that can be adapted for numerous civilian and military operations. Users of the surgical versions of these shelters, namely, the U.S. Army Medical Materiel Development Agency, have reported undesirable bounce or springing effects when personnel traverse the floor regions. This report documents the structural analysis of the S-786 shelter in the fully deployed position that was conducted to determine if the shelter floor vibrations could be mitigated.
