Structural Engineering Calcs

Structural Evaluator is a fast, modern screening tool for engineers, students, inspectors, and technically-minded homeowners who need quick preliminary checks on houses, bridges, buildings, and retaining walls. Pick a structure type, enter its key properties, and get an instant summary of the numbers that matter — total gravity load, midspan moment, earth pressure, slenderness ratio, and automatic warnings for age, seismic zone, and geometry limits. KEY FEATURES Structure Assessment — Four structure types with type-specific inputs. Houses, bridges per AASHTO HL-93, multi-story buildings with lateral systems, and retaining walls with Rankine earth pressure. Beam Analysis — Simply-supported beam checks under uniform or point loads. Maximum moment, shear, deflection, bending stress, and pass/fail demand/capacity ratio with L/360 serviceability check. Column Analysis — Euler buckling plus yield-cutoff capacity with four end-condition options. Slenderness-ratio warnings and clear pass/fail verdicts. Photo Capture — Take photos or pick from your library for visual condition documentation, with a Core ML-ready pipeline for future defect detection. Material Library — Built-in reference for A36 and A992 steel, 3000 and 4000 psi concrete, Douglas Fir-Larch and Southern Pine wood, and 6061-T6 aluminum. Cross-Sections — Rectangular, circular, and I-beam sections with automatic computation of area, moment of inertia, section modulus, and radius of gyration. Clean Modern UI — Dark navy gradient backgrounds, amber accents, glass-style cards, and large pass/fail result seals optimized for at-a-glance reading in the field. IMPORTANT DISCLAIMER Structural Evaluator is a preliminary screening and educational tool. Results are not a substitute for analysis, design, or certification by a licensed Professional Engineer. Always consult a qualified engineer before making safety-critical decisions about any real structure. What's New (for v1.0 launch, 4000 char max) Initial release.
