App Description
Precision Engineering on the go.
RC Designer is a mobile tool built specifically for structural engineers, consultants, and students working within the Hong Kong construction industry. Designed strictly according to the Code of Practice for Structural Use of Concrete 2013 (HK COP 2013), this app streamlines the complex process of reinforced concrete member design.
KEY FEATURES:
Comprehensive Beam Design:
Flexure Design: Supports both Singly and Doubly reinforced sections.
Automatic Detailing: Intelligent rebar arrangement based on section width (Width/100 - 1) or manual override.
Shear Links: Calculate required links (S.S, D.S, T.S, or Multi-leg) based on V/vc limits.
Deflection Check: Real-time Span/Effective Depth ratio verification with modification factors.
Detailed Traceability: View full calculation steps with direct references to HK COP 2013 Clauses.
Advanced Column Design:
Biaxial Bending: Interactive M-N Interaction Curves for both X and Y axes.
Slenderness Effects: Calculation of additional moments based on effective height.
Visual Detailing: Dynamic cross-section sketches showing rebar layout.
Rectangular and circular columns supported.
Multiple load cases from ETABS outputs supported.
Disclaimer:
This app is intended for use by qualified structural engineers for preliminary design and checking purposes. All final designs must be verified against official code documents and independent calculations.
