SBCP runs NDS ASD and AISC 360‑22 LRFD beam checks with every adjustment factor, load combination, and governing case in plain sight — then prints a calculation package worth putting your stamp on.
One-time license — no subscription. Includes 12 months of updates & support.
Subscription calc suites print a summary and keep the derivation to themselves. SBCP was built the other way around: the adjusted allowable stress equations, the factor chain behind each one, and the governing ASCE 7 combination are first-class output — in the app and in the report.
SBCP does beams thoroughly instead of sixty modules shallowly. Additional calculation packs are in development.
Sawn lumber, glulam, and structural composite lumber with bending, shear, bearing, and deflection DCRs, self-weight handling, and sloped-roof members.
Flexure, shear, and deflection checks with LTB from effective unbraced length, compactness, blocking/joist or L-angle bracing, and Appendix 6 brace forces.
Two-span continuous analysis with optional free-end cantilever spans, per-span DCR envelopes, reactions, and full diagram output.
NDS Supplement species/grade tables, glulam layups and sizes, and ESR-based LVL, PSL, and LSL products — with provenance and review status on every record.
Uniform, trapezoidal, and point loads; psf × tributary width conversion; dead, live, roof live, snow, wind, and seismic cases; reactions carried between members.
A project file holds every member. Re-run the entire calc set with one click, see pass/fail and governing DCR per row, and import calcs from previous projects.
Pass/fail banner, DCR summary grid, beam and envelope diagrams, and a tabulated calculation trace appendix — under your firm's logo and the EOR's license number.
Live diagrams with labeled extremes as you edit, Vmax and Vdesign at d from supports, and SVG export.
A native C++ Windows app: instant startup, no browser, no cloud round-trips. Client and project data never leave your machine.
From a real SBCP project: a residential addition with a floor beam, LVL ridge, steel garage header, and a continuous hallway beam.
Every report is generated from structured results — never hand-formatted text — with a project summary page, per-member detail pages, diagrams, and a tabulated trace appendix a reviewer can audit line by line.
SBCP is in early access with a working group of practicing structural engineers. Request a seat, get a license within a business day, and put real project beams through it.
