Proposed Container Home

Project Details

This project involves the structural analysis and engineering design for a multi-story residential structure utilizing repurposed 8’x20′ shipping containers integrated with modern steel and timber framing. The comprehensive scope required engineering solutions for a complex assembly of existing container frames, new HSS 2.25″x2.25″x0.25″ steel posts (A500 Gr. B), and structural knee braces to ensure stability. The secondary framing incorporates Douglas Fir No. 2 timber for ceiling joists, floor blocking, and stair stringers to provide a durable interior living space. The design process utilized 3D finite element modeling to perform a rigorous structural analysis, ensuring the assembly can safely withstand regional environmental loads. The structure was engineered in accordance with the International Building Code (IBC 2021), the Oregon Building Code, and ASCE 7-16 provisions.
Specialized attention was directed toward lateral load resistance, with the structure designed to withstand wind speeds of 97 MPH and seismic requirements defined by a Spectral Response Acceleration (SDS) of 0.742. The foundation system is a hybrid design featuring an existing 6″ thick concrete slab, reinforced concrete pad footings, and 2-7/8″ diameter helical piles equipped with Tru-Lift brackets, all designed for a soil bearing capacity of 1,500 psf.

Role

Structural Engineer/Designer

Services Provided

The scope of services includes the preparation of structural analysis and structural plans for the proposed structure. Structural analysis shall include complete gravity load analysis, including live loads, dead loads, snow loads, and other applicable vertical loads, as well as lateral load analysis for wind and earthquake forces in accordance with the governing building code and site conditions. The work shall involve determining the calculated loads and corresponding capacities of structural members identified in the plans to ensure that all structural elements are capable of safely resisting both gravity and lateral demands. The analysis shall verify that the structure maintains a continuous and code-compliant load path while meeting strength and serviceability requirements.

The services shall also include the preparation of structural plans identifying all required structural members and framing systems. The drawings will clearly indicate the location and designation of structural elements, along with structural connection details and sections as required to communicate the design intent and construction requirements. Where applicable, the scope shall also include design recommendations and plans for retrofit modifications, if necessary, to ensure the structure meets applicable safety and performance standards. All documents shall be prepared to facilitate plan review, coordination, and accurate implementation during construction.
