Why StructSuite Exists

Traditional engineering software hasn't kept pace with modern construction demands. Engineers and reviewers still struggle with:

• Slow, outdated desktop workflows
• Black-box calculations with limited transparency
• Fragmented alignment across NDS 2024, 2024 IBC, and ASCE 7-22
• Time-consuming plan check revisions
• Inconsistent documentation and unclear assumptions in calc packages

StructSuite addresses these with a unified, cloud-based platform built for speed, clarity, and approval efficiency.

A Modern Engineering Platform Built for Real-World Practice

Built on adopted code editions

StructSuite targets wood and related structural work using adopted code editions, including:

• NDS 2024 (National Design Specification for Wood Construction) for wood member design
• 2024 IBC structural provisions where the modules apply them (e.g., wood, deflection limits)
• ASCE 7-22 for wind loads, seismic loads, snow, and load combinations as implemented in each workflow
• SDPWS 2021 (Special Design Provisions for Wind and Seismic) and NDS 2024 for wood-frame shear wall design where applicable
• ACI 318-25 for concrete foundation modules where the tool cites that edition

Available today

• Cover Sheet — Create professional cover sheets for structural calculation reports. Add project title, address, client info, engineer stamp, and company branding per standard practice.
• Dead and Live Loads — Build dead and live loads per ASCE 7-22. Assemble dead loads from material and assembly weights (Table C3.1-1a) for roofs, floors, walls, and ceilings; assign live loads by occupancy (Table 4.3-1) with roof live loads (Lr) and live-load reduction — summarized for gravity load combinations.
• Seismic Loads — Calculate seismic base shear and story forces per ASCE 7-22 Chapter 12 (Equivalent Lateral Force). Site class and spectral parameters, risk category and importance factor, seismic force-resisting system (R, Cd, Ω0), period, response coefficient Cs, vertical and horizontal force distribution, and diaphragm design forces (Fpx).
• Wind Loads — Calculate wind loads per ASCE 7-22. Exposure category, topographic, and velocity-pressure parameters, then design wind pressures on the Main Wind Force Resisting System by both the Directional (Chapter 27) and Envelope (Chapter 28) procedures, including the wind load cases.
• Wood & Steel Beam — Design wood beams per NDS 2024 — sawn lumber, glulam, I-joists (TJI, BCI), LVL, LSL, and PSL — or steel beams per AISC 360-22 (LRFD) with W-shapes, rectangular/square and round HSS, and pipe from the AISC Shapes Database. Build the load case from ASCE 7-22 load types (D, L, Lr, S, W, E, etc.) with uniform, point, and triangular/trapezoidal loads over single- or multi-support spans; checks moment, shear, and deflection — with full NDS adjustment factors for wood and compactness/lateral-torsional buckling per AISC Chapter F for steel. Switch between the wood and steel design of the same beam to compare sizes on screen.
• Floor/Ceiling Joist & Rafter — Prescriptive span tables for floor joists, ceiling joists, and rafters per 2024 IBC Chapter 23 (Tables 2308.8 and 2308.11), plus Trus Joist® TJI® engineered I-joist spans. Allowable spans by species, grade, size, spacing, and loading.
• Wood & Steel Column — Design wood columns per NDS 2024 — sawn lumber, glulam, LVL, LSL, and PSL with the column-stability factor CP — or steel columns per AISC 360-22 (LRFD) with W-shapes, rectangular/square and round HSS, and pipe from the AISC Shapes Database, including flexural buckling (Ch. E) and slender-element sections (E7). Effective-length (Ke) factors for pinned, fixed, and sway end conditions per axis; ASD combinations for wood, LRFD for steel. Switch between the wood and steel design of the same column to compare sizes on screen.
• Wood-Frame Shear Wall — Design wood-frame shear walls per SDPWS 2021 and NDS 2024 for wind and seismic. Distribute story shear to wall lines from the building plan, unit shear capacity by wood species and sheathing, hold-down (tie-down) forces, base shear transfer (anchor bolts and framing clips), with ASCE 7-22 load combinations.
• Isolated & Strip Footing — Design isolated (column) and strip footings per ACI 318-25 with ASCE 7-22 load combinations. Soil bearing, flexural reinforcement with minimum steel, and one-way and two-way (punching) shear.
• Cantilever Retaining Wall — Design cantilever concrete retaining walls per ACI 318-25, IBC 2024 and ASCE 7-22. Overturning and sliding stability (IBC 1807.2.3), soil bearing, stem/heel/toe strength design, and reinforcement development with IBC Table 1610.1 and ASCE Table 3.2-1 lateral soil loads.
• Simpson Strong-Tie connectors — Connector and hold-down selection built into the wood beam, joist/rafter, and shear wall workflows.
• Print-ready reports (Pro) — Assemble modules into a professional PDF report with a public plan-check verification link.
• Cloud-saved projects (Pro) — Save projects and revisions to the cloud and access them from any device.

Coming soon

• Steel beam design
• Steel column design
• Simpson Strong-Wall and prefabricated wall systems — Additional Simpson Strong-Tie wall systems in the shear wall workflow.
• Simpson Strong-Tie connectors for wood columns
• Additional design modules, rolled out continuously — see the release notes

Calculations are presented with traceable formulas, intermediate values, and citations to the relevant code sections (for example, NDS 2024, ASCE 7-22).

Simpson Strong-Tie Integration

StructSuite integrates Simpson Strong-Tie connectors directly into the workflow — available today in the wood beam, joist/rafter, and shear wall modules — so engineers can select and verify connectors inside the tool, reduce manual lookups, and stay aligned with NDS 2024 and manufacturer criteria. Wood column connector support and Simpson Strong-Wall prefabricated wall systems are next on the roadmap.

Cloud-Native by Design

StructSuite is built for modern engineering teams:

• No installation or local updates to run the web application
• Access from any device with a browser
• High-performance, responsive interface
• Code logic and reference libraries maintained in the cloud
• Cloud-saved projects and revisions stored centrally (Pro)

Firms gain a standardized workflow that works anywhere you can reach the app.

Plan-Check-Ready Documentation

StructSuite produces professional, reviewer-friendly reports designed to reduce comments and accelerate approvals.

Each report includes:

• Step-by-step engineering calculations
• Clear assumptions and criteria
• Code references to NDS 2024, 2024 IBC, ASCE 7-22, and related standards as cited in the module output
• Transparent engineering logic
• Organized, easy-to-review formatting

Plan check engineers get clarity. Designers get fewer revisions. Firms get faster turnaround.
