Proposed Main House (The Marilyn) and Garage

Project Details

This project involves the structural design and engineering of a two-story residential farmhouse, “The Marilyn,” and an accompanying detached garage. The comprehensive scope required modern engineering solutions for the entire structural assembly, including cold-formed steel (CFS) wall studs, floor trusses, and roof trusses. The primary structural system utilizes high-strength structural steel beams (W8X15 and W10X30) and hollow structural section (HSS) columns integrated with CFS framing to ensure a durable and lightweight assembly.The design process included a rigorous structural analysis using Tekla TEDDS and STAAD.Pro Connect Edition to ensure the building could safely withstand environmental loads. The structural elements were engineered in accordance with the Florida Building Code (2023 Ed.), IBC 2021, and ASCE 7-22 provisions. Special attention was given to lateral load resistance through the implementation of roof and floor diaphragms utilizing 15/32″ plywood sheathing and Simpson Strong-Tie holdowns (S/HDU6 and S/HDU9). These systems provide essential stability against wind speeds of 146 MPH and meet the requirements for Seismic Design Category A. The foundation system features a 4″ thick reinforced slab-on-grade supported by concrete wall and pad footings designed to perform reliably under a soil bearing capacity of 2,000 psf.

Role

Structural Engineer/Designer

Services Provided

The scope of services includes the preparation of comprehensive structural calculations and structural drawings for the proposed Main House and Garage. Structural calculations shall include complete loading analyses for wind, seismic, dead, and live loads, in accordance with the governing building codes and project site conditions. The work shall encompass the analysis and design calculations for all new structural elements, including foundations, shear walls, load-bearing walls, columns, beams, floor joists, trusses, connectors, and other related structural components required to safely support and transfer gravity and lateral loads. The calculations shall verify that all structural members and systems provide a continuous and code-compliant load path from the roof and floor systems down to the foundation.

Structural drawings shall include a Foundation Plan indicating the layout and sizing of footings and foundation elements; a Second Floor Framing Plan identifying framing configuration and member sizes; and a Roof Framing Plan showing trusses, beams, and roof diaphragm components. The drawing set will also include First Floor and Second Floor Shear Wall Layout Plans defining the lateral force-resisting system, as well as structural sections to clearly illustrate framing relationships and vertical load paths. In addition, the structural documents shall include typical structural details, general structural notes, and specifications necessary to communicate design intent, support plan review, and facilitate accurate construction while ensuring compliance with applicable codes and engineering standards.
