Staircase Calculator is a professional structural engineering app designed for calculating advanced staircase geometry, structural steel design, and code compliance. It is the ultimate digital tool for civil engineers, structural engineers, architects, steel fabricators, and construction professionals.

Quickly calculate precise dimensions, optimize member sizing, and analyze load layouts directly from your mobile device using both Imperial (Ft + In + Fractions) and Metric measurement systems across global standards.

Key Features & Engineering Tools:

• ADVANCED GEOMETRY CALCULATOR
Input dimensions cleanly with full Imperial fraction or Metric unit support. Automatically calculates precise staircase layouts, riser heights, tread depths, and generates a detailed side-view diagram.

• STRUCTURAL STEEL DESIGN & DATABASES
Fully integrated with the AISC 16th Edition steel standards. Design and optimize structural stair frames using both LRFD and ASD design methods. Features comprehensive, built-in databases for C-Channel, W-Section, and MC-Channel profiles, plus a custom section library.

• COMPLIANCE & SAFETY VERIFICATION
Built-in automated checks for International Building Code (IBC) and International Residential Code (IRC) compliance. Features a 3-rules stair comfort verification system to ensure optimal, safe footing ergonomics.

• LOAD ANALYSIS & ESTIMATION
Perform rigorous engineering analysis with custom or code-based load inputs, including dedicated Wind and Seismic load analysis modules. Instantly estimate project material costs in both USD and INR.

• PROFESSIONAL REPORTS
Keep track of your projects with a local calculation history log and export comprehensive, print-ready PDF engineering reports to share with your clients or building inspectors.

Supported Steel Grades:
A36, A572 Gr.50, A992, and global equivalents.
