AISC 360 Structural Design in the USA

AISC 360-22 member design under IBC 2021 and ASCE 7-22 — including delivered Florida waterslide steel supports under FBC + AISC 360 — PE-review-ready packages from senior engineer Mubashir.

AISC 360 Structural Design for US Projects

The United States building construction market operates on a mature, well-documented code system centred on the International Building Code (IBC), ASCE 7 for loads, and AISC 360 for structural steel member design. For US clients seeking structural engineering support for steel-framed buildings, entertainment structures, industrial platforms, or specialty steel frames, the engineering deliverable must satisfy the IBC framework and be packageable for review by a US-licensed Professional Engineer who will serve as engineer of record for local authority submission.

Sixteens Consultancy Services provides complete AISC 360-22 structural design packages for US clients. We have delivered built US work — the Florida waterslide steel supports project, designed to Florida Building Code (FBC) 2023 and ASCE 7-22 wind provisions, is a direct deliverable reference. Our calculation packages are structured for straightforward PE review and AHJ (Authority Having Jurisdiction) submission.

Code Framework in the USA

US structural steel design requires competency across a layered set of interlocked standards:

  • AISC 360-22 (16th Edition) — The primary specification for structural steel buildings. Governs all member strength checks: Chapter D (tension), Chapter E (compression with column buckling curves), Chapter F (flexure including lateral-torsional buckling), Chapter G (shear), and Chapter H (combined loading). Load combinations use ASCE 7-22 Section 2.3 (LRFD) or Section 2.4 (ASD).
  • ASCE 7-22 — Minimum Design Loads and Associated Criteria. The load standard that feeds into AISC 360. Chapter 26–31 cover wind loads using updated wind speed maps from the 2022 edition. Chapter 11–22 cover seismic, with significant revisions to risk-targeted Maximum Considered Earthquake (MCER) mapping versus the 2016 edition.
  • IBC 2021 — International Building Code adopted (with state amendments) across most US jurisdictions. Establishes occupancy categories, fire ratings, and the code compliance pathway that links ASCE 7 and AISC 360 into an enforceable regulatory framework.
  • FBC 2023 (Florida Building Code) — Florida's adoption of IBC with substantial amendments. Most critically, HVHZ (High-Velocity Hurricane Zone) provisions in Southeast Florida require wind pressures derived from 185 mph (3-second gust) speed maps, applied to both structural systems and components and cladding. Our Florida waterslide project navigated these requirements successfully.
  • AISC 341-22 / AISC 358-22 — Seismic provisions and prequalified connections apply to structures in seismic zones, including California, Pacific Northwest, New Madrid zone, and parts of the Southeast. AISC 341-22 prescribes special moment frame (SMF), intermediate moment frame (IMF), and special concentrically braced frame (SCBF) systems with specific ductility detailing.

SCS Track Record in the USA

The Florida waterslide steel supports project is our completed US reference. This project involved designing the structural steel support framework for a waterslide attraction — a structure type that combines high live loads, dynamic loading from water and riders, fatigue considerations, and FBC wind requirements for an outdoor recreational installation in Florida's hurricane exposure zone. The design required ASCE 7-22 wind load determination with FBC HVHZ adjustments, AISC 360-22 member design for tubular steel sections under combined axial, bending, and torsion, and bolted connection design to AISC 360-22 Chapter J. The structure was completed and is in operation.

The project demonstrates our ability to work within US-specific code requirements, produce calculation packages formatted for US PE review, and deliver work for structures subject to demanding environmental loads.

How to Engage SCS for AISC 360 Design in the USA

Email [email protected] with: project state and county (to identify applicable building code amendments and wind/seismic data), structure type and occupancy category, approximate size and height, any existing architectural or preliminary drawings, and your PE of record relationship (or ask us to recommend a review model). Mubashir responds personally within one business day. Our deliverables are PDF calculation packages with full code references, AutoCAD drawings, and a connection force schedule — all structured for straightforward PE review and AHJ submission.

AISC 360 Design in the USA
— Common Questions

Can a structural engineering firm outside the US design to AISC 360 for US projects?

Yes. AISC 360 is a published standard available to engineers worldwide. SCS provides the full AISC 360-22 design package; US clients arrange the PE stamp through their local engineer of record, who reviews and signs our calculations for AHJ submission. This is a standard model for international design consultants working on US projects.

What makes Florida structural design different from other US states?

Florida uses the FBC with IBC amendments. The most significant difference is HVHZ requirements in Miami-Dade and Broward Counties, where wind pressures reach up to 185 mph (3-second gust) and structural, cladding, and impact resistance requirements exceed ASCE 7 minimums. SCS has delivered structural work under FBC HVHZ conditions on the Florida waterslide supports project.

Which AISC design guides apply to recreational and entertainment steel structures?

Relevant references include AISC Design Guide 1 (Column Base Plates), Design Guide 9 (Torsional Analysis), and Design Guide 21 (Welded Connections). AISC 360-22 Chapter H governs combined loading on columns — critical for tower and frame structures — and Chapter J covers bolted and welded connection design. AISC 360-22 Appendix 3 covers fatigue for cyclically loaded structures.
