Zuni Solid Waste Complex

Project Details

This project involves the structural design and engineering of the cold-formed metal framing (CFS) for the Zuni Solid Waste Complex, a facility measuring approximately 116′-4″ by 44′-0″. The comprehensive scope of work included structural analysis and design calculations for load-bearing walls, non-structural partitions, headers, jambs, and ceiling framing assemblies. The structure utilizes high-strength galvanized steel sections, primarily featuring 6-inch and 8-inch “S” stud profiles (20 GA and 18 GA) integrated with boxed headers and track systems to ensure a robust and durable assembly. The design process featured a rigorous structural analysis, including finite element modeling for the ceiling framing and detailed wind loading analysis using the directional design method. Structural elements were engineered in strict accordance with the International Building Code (IBC 2021), ASCE 7-22, and AISI S100-16 provisions. Special consideration was given to lateral and environmental load resistance, with the framing designed to withstand wind speeds of 103 MPH (Exposure Category C) and meet requirements for Seismic Design Category B. The design further incorporates specialized Simpson Strong-Tie connection solutions, such as slide-clips and rigid connector angles, to manage axial and shear forces reliably under a defined soil bearing capacity of 1,500 psf.

Structural Engineer/Designer

Services Provided

The scope of services included the preparation of delegated cold-formed metal framing (CFMF) structural calculations and drawings for the project in accordance with IBC 2021, AISI S100, AISI S240, and applicable New Mexico amendments. The work involved the analysis and design of loadbearing and non-loadbearing CFMF wall studs, tracks, and headers as indicated on the architectural drawings, including anchorage to slab-on-grade, foundations, and structural steel framing where required. Deflection and drift compatibility evaluations were performed to coordinate CFMF partitions with the primary structural steel framing and braced frame systems, and slip tracks and movement joints were designed to accommodate anticipated floor and roof deflections. The design also considered coordination requirements for fire-rated, acoustic-rated, and impact-resistant wall assemblies. Structural drawings were prepared to illustrate the CFMF framing layout, elevations, stud sizes, gauges, spacing, bracing requirements, connection details, head-of-wall and slip-track conditions, and other typical construction details. Structural notes and specifications, including details for rated partitions, control joints, and coordination with architectural assemblies, were included to support permitting, coordination, fabrication, and installation of the framing system.
