Deterministic, Peer-Auditable
Structural Engineering Mechanics
StructLogic was founded to eliminate opacity in civil and structural engineering computation. By combining classical continuum mechanics with governing building codes, our platform delivers open-access, verifiable, client-side engineering tools with absolute mathematical transparency.
Four Pillars of the StructLogic Platform
Deterministic Mechanics
Every calculation is grounded in closed-form analytical solutions: fourth-order Euler-Bernoulli elastic curve differential equations for flexure, Rankine and Coulomb earth pressure formulations for retaining structures, and ACI 318 equivalent stress block equilibrium. There are no stochastic approximations or undisclosed empirical factors.
Governing Code Harmonization
Algorithms are explicitly cross-referenced to the current standard editions: ACI 318-19 (Reinforced Concrete), AWC NDS-2024 (Wood Construction), AISC 360-22 (Structural Steel Buildings), IBC 2024, and ASCE 7-22 (Design Loads). All adjustment factors ($C_D, C_M, C_t, C_L, \phi, \Omega$) are made fully visible to the practitioner.
Zero Telemetry & 100% Client Memory
Engineering proprietary specifications, span dimensions, and project coordinates belong exclusively to you. Calculations execute entirely inside client browser memory using static web delivery. No user tracking daemons, analytics scripts, or third-party tracking cookies are installed or permitted.
Peer-Auditable Intermediate Proofs
Black-box software produces unverified answers that invite catastrophic blind spots. StructLogic exposes intermediate algebraic derivations, shear matrices, and moment diagrams, empowering licensed Professional Engineers (PE/SE) to perform step-by-step audits prior to permit submission.
Algorithmic Benchmark Validation
Every numerical routine in StructLogic undergoes automated regression testing against published, peer-reviewed engineering benchmarks:
Douglas Fir-Larch #2 (2x10 @ 16" o.c., 40 psf Live, 10 psf Dead, L/360 deflection limit) clear span exactly verified at 16'-1" against AWC Residential Span Tables Table 1A.
Whitney rectangular stress distribution (β1 = 0.85 for f'c ≤ 4,000 psi) and nominal flexural capacity (Mn = As fy(d - a/2)) verified against PCA Notes on ACI 318.
Active earth coefficient $K_a = \tan^2(45^\circ - \phi/2) = (1 - \sin\phi)/(1 + \sin\phi)$ tested against Bowles Foundation Analysis standards across internal friction angles $\phi \in [24^\circ, 42^\circ]$.
The StructLogic Engineering Consortium
StructLogic operates as an independent technical consortium dedicated to advancing open engineering knowledge. Our computational suite is built with modern static web standards (TypeScript 5 strict mode, Next.js static export, and zero telemetry) to provide a resilient, perpetual public reference for licensed structural engineers, civil engineers, architects, plan reviewers, and engineering students worldwide.
For technical audits, errata submissions, or inquiries regarding equation derivations, please review our governing proofs on the main portal or refer to our published verification documentation.
