Calculations
Interactive calculators for reinforced-concrete and steel design.
In-browser calculators: bending resistance of reinforced-concrete beams per EN 1992-1-1, stiffness modification of an RC beam integrated into a slab, and stabilizing forces per EN 1993-1-1.
Beam — Bending Resistance
Design bending resistance Mᵣd of a singly reinforced rectangular RC cross-section using the rectangular stress block.
Stiffness Modification
Simplified stiffness modification of a reinforced-concrete beam integrated into a slab, for FEM analysis of slab-beam systems.
Bracing Imperfection
Equivalent horizontal force from initial sway / bow imperfections for bracing and stabilising members per EN 1993-1-1.
