3225 Firestone – Proposed Convenience Store & Trash Enclosure
Project Details
This project involves the structural analysis and engineering design for a proposed convenience store and a detached trash enclosure. The comprehensive scope required modern engineering solutions for the entire structural assembly, including the design of load-bearing cold-formed steel (CFS) wall studs (350S162-43) and primary structural steel beams (HSS 10x6x3/8 and HSS 8x3x3/8) to support gravity and lateral loads. The detached trash enclosure utilizes a steel framing system consisting of HSS 4×2 purlins and beams supported by HSS 4×4 columns and gate posts. he design process included a rigorous loading analysis performed in accordance with the International Building Code (IBC 2021), the 2022 California Building Code, and ASCE 7-16 provisions. Structural elements were engineered to withstand a roof dead load and live load of 20 psf each. Special attention was given to lateral load resistance, with the convenience store engineered for high-seismic requirements (Seismic Design Category D) and stability against wind speeds of 95 MPH. Lateral stability is provided by steel shear walls utilizing 0.018” and 0.027” steel sheeting integrated with Simpson Strong-Tie S/HDU4 and S/HDU6 hold-downs. The foundation system features independent reinforced concrete pad footings (PF-1 and PF-2) designed to perform reliably under an allowable soil bearing capacity of 1.5 ksf.
Role
Structural Engineer/Designer
Services Provided
The scope of services includes the preparation of comprehensive structural calculations and structural drawings for the main structure and the associated trash enclosure. Structural calculations shall include complete loading analyses covering wind, seismic, dead, and live loads in accordance with the applicable codes and site conditions. The work shall encompass the structural analysis and design of all structural elements of the main structure and trash enclosure, including but not limited to foundations, slabs, columns, beams, roof framing members, and lateral load-resisting systems such as shear walls, ensuring a stable, continuous, and code-compliant load path.
Structural drawings shall include the Main Structure Foundation Plan and Roof Framing Plan based on existing conditions, as well as the Shear Wall Layout Plan and corresponding Structural Sections to clearly define the lateral and vertical systems. For the trash enclosure, drawings shall include the Foundation Plan, Roof Framing Plan, Framing Elevations per gridline, and Sections to fully illustrate the structural configuration. The drawing set will be supplemented with typical structural details, general notes, and technical specifications necessary for permitting, coordination, and construction, ensuring clarity, constructability, and compliance with applicable engineering standards.
