Structural Engineering Studio
LRFD Calc - Simulate - Learn
£5.99 · Designed for iPad. Not verified for macOS.
Eight professional LRFD calculators, eight animated structural simulations, and a full curriculum — built for engineers and engineering students.
Structural Engineering Studio is a comprehensive learning and reference platform for structural engineering students, engineers-in-training, and practicing professionals. It combines professional-grade design code calculators, animated structural simulations, a structured curriculum, personal study notes, and a searchable reference library in a single focused app.
Calc Hub — 8 Professional Calculators
The Calc Hub tab delivers real engineering computations based on current design codes. Calculators include AISC 360 LRFD beam flexure checks (φMn with utilization ratio), AISC 360 LRFD column capacity (Euler buckling, KL/r, Fcr, φPn), beam reaction diagrams for three support conditions, deflection-to-span ratio verification for live and total loads, ASCE 7 seismic base shear using the Equivalent Lateral Force procedure, ASCE 7 wind velocity pressure and net cladding pressure, ACI 318-19 reinforced concrete section flexure (depth of stress block, φMn, reinforcement ratio checks), and a five-category SI/Imperial unit converter covering force, stress, length, moment, and mass. Every calculator displays intermediate values, utilization ratios, and pass/fail status.
Interactive Simulations
Eight animated Canvas-based simulations let you explore structural behavior in real time. Adjust parameters with sliders and watch physics-accurate results update instantly. Simulations cover beam deflection under point and distributed loads with three support conditions, Euler column buckling with adjustable end conditions and slenderness ratio, gravity and lateral load path tracing through diaphragms and shear walls, stress-strain curves for steel, concrete, and timber, single-degree-of-freedom seismic response spectra, ASCE 7 wind pressure on building envelopes, cross-section property visualization for W-shapes and HSS, and foundation settlement estimation for shallow footings.
Structured Curriculum
A seven-module learning path covers statics fundamentals, structural materials, beams and bending, columns and compression, lateral load systems, connections and detailing, and advanced topics including finite element analysis concepts. Eighteen lessons include written content, worked examples with embedded code, and quiz questions with instant feedback.
Personal Study Notes
Every lesson includes a dedicated notes panel. Write, edit, and save your own annotations directly within the app. Notes persist between sessions and are stored locally on your device — ideal for exam preparation and professional reference.
Bookmarks
Bookmark any lesson and access it instantly from the Home tab via a horizontal quick-access strip. Return to saved content without navigating through the full curriculum.
Reference Library
A searchable and filterable library of structural engineering formulas, code citations, material properties, and design aids covering steel, concrete, timber, and masonry design.
Gallery
Thirty-plus annotated engineering illustrations organized into six categories: structural fundamentals, component types, lateral and seismic systems, structural health monitoring, finite element analysis, and applied case studies.
Guided Projects
Five design projects walk through a multi-story steel frame, a reinforced concrete beam, a lateral bracing system, a truss bridge, and a foundation system — with step-by-step instructions and embedded design code references.
