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• Slow, outdated desktop workflows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), including the roof live load L_r, at the tabulated values — a reduced live load is entered if one is taken — and summarize them as the project's gravity loads.
• 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, C_d, Ω₀), period, response coefficient C_s, base shear, the vertical distribution of story forces with story shears and overturning moments, and diaphragm design forces (F_px).
• 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, LPI), 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, L_r, S, W, E, etc.) with uniform, point, and triangular/trapezoidal loads over single- or multi-support spans; checks moment, shear, deflection and bearing — with the 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, with the ceiling-height rafter adjustment and optional Simpson Strong-Tie hanger selection.
• Wood & Steel Column — Design wood columns per NDS 2024 — sawn lumber, glulam, LVL, LSL, and PSL with the column-stability factor C_P — 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 (K_e) 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. Model the walls on a building plan and distribute the story shear to the wall lines by tributary area and length, unit shear capacity by wood species and sheathing (Table 4.3A), hold-down (tie-down) tension and end-post (compression chord) forces from overturning, Simpson Strong-Tie hold-down and SABR anchor-bolt selection, end-post design per NDS 2024 and collector (drag strut) forces, 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 (kern-aware or biaxial with partial contact), overturning and sliding, flexural reinforcement with minimum steel, one-way and two-way (punching) shear, bearing at the support and development length.
• 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 and shear-key strength design, and reinforcement development — with IBC Table 1610.1, ASCE Table 3.2-1 or a geotechnical equivalent fluid pressure, sloped backfill, seismic earth pressure (Mononobe-Okabe, Seed-Whitman or the report's own ΔP_AE), groundwater, a footing behind the wall, wind on the stem and on a fence, a stepped stem, and a stem of solid-grouted concrete masonry (CMU) designed by TMS 402-22 allowable stress design on the same concrete footing.
• 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 — Save projects to the cloud and open them from any device: one project with a free account, unlimited with Pro.

Coming soon

• 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
