Method — Screening-level estimate
Element geometry with declared section sizes and a wastage margin. NOT a structural design: no reinforcement design, no code verification, no member sizing check.
Every result below is produced by the same engineering engine that feeds the High-Rise reference project, so a quantity taken from this page and a quantity taken from the workflow cannot disagree.
Governing Formula
Governing Formula
V_beams = n_lines x L x levels x b x d Where:
-
n= Beam lines per floor -
L= Beam length per line [m] -
b x d= Beam cross-section [m2]
Derived Equations:
Core / shear wall volume:
V_core = A_core x t x levels Stair volume:
V_stair = risers x going x width x flights Formwork area:
A_form = vertical faces + (A_plate x levels x multiplier) Assumptions & Limitations
- No reinforcement is produced here; add it from a bar schedule or a dedicated rebar calculator.
- No structural capacity, deflection, crack-width or code-compliance check is performed.
- Assumes a regular frame; transfer structures, openings and irregular cores are out of scope.
