is a highly specialized structural engineering software developed by Hussein Rida, PE, designed specifically for the analysis and design of reinforced concrete elements. The application automates complex cross-sectional calculations by strictly enforcing the American Concrete Institute (ACI) design criteria, primarily focusing on the ACI 318 code series. Unlike generic finite element analysis (FEA) suites, version 17.8.5 acts as a dedicated section designer that processes specific load demands to generate code-compliant geometry, reinforcement detailing, and comprehensive step-by-step engineering calculation notes. Core Engineering Capabilities
The ability to generate detailed design reports makes reviewing calculations straightforward, simplifying the approval process for structural drawings. 4. Educational Utility
: Includes tools to manage immediate and long-term deflection for beams and slabs, as well as an enhanced algorithm for calculating flexural crack width. Rcm Aci Builder V17.8.5
Generates full P-M (Axial Force vs. Bending Moment) interaction diagrams. It evaluates slenderness effects, determines unbraced lengths, and designs optimal tie or spiral configurations for seismic and non-seismic zones.
Generates step-by-step mathematical proof documents. These reports display formulas, code section references, and final pass/fail statuses, which are ideal for submission to municipal plan checkers. 4. Step-by-Step Design Workflow Generates full P-M (Axial Force vs
The software strictly adheres to modern ACI 318 code requirements (including provisions from ACI 318-19). It accurately applies code-mandated strength reduction factors (
Computes shear reinforcement requirements based on applied loads. code section references
Disclaimer: Always verify structural design calculations using independent methods, as software outputs are dependent on input accuracy and interpretation of design codes.
The platform is primarily recognized for its "open book" design philosophy, providing detailed reports that include full formulas and illustrative figures similar to manual hand calculations. : Analyzes rectangular and T-shape sections.
