Lateral strength of corrugated walls with trapezoidal geometry of transoceanic shipping containers

Refurbished, transoceanic shipping containers are an option for permanent housing. As a structural system, the primary lateral force resisting components are corrugated walls with trapezoidal geometries. Due to the lateral force demands from wind and seismic loads, the shear capacity of the walls must be investigated. This paper analyzes three conditions of stacked double wide container homes under lateral loads from wind and seismic in both directions. A range of seismic parameters is considered in order to simulate difference geographic regions. Equations describing required shear wall lengths as a function of geographic region are developed. From this analytical study, the corrugated walls of transoceanic shipping containers are considered adequate as the lateral force resisting system.
