π 3D Section Resultants & Forces Integrator (cutres)
Integrates Cauchy stress traction across a planar intersection with 3D solid elements to evaluate resultant beam action effects (N, V, M, T) and Eurocode design parameters.

Click 'Detect' to auto-fit soil block to existing building nodes and detect support elevation.
ποΈ Foundation Embedment in Terrain
Structural supports can be located in some depth of terrain (e.g. frost depth, basement footing level). Specify the embedment depth to vertically align the subsoil terrain with the building.

π Frame Dimensions & Member Discretization
βοΈ Arbitrary Member Discretization (In-Span Hinge Capture)
Plastic hinges under distributed gravity load or wind often occur within member spans rather than at joints. Configure intermediate finite element divisions to detect in-span field yield points.
Default: 16 elements (fine in-span plastic hinge capture)
π‘ Strong Column - Weak Beam Design: Columns typically utilize wider flange sections (e.g. HEB/HEA) to resist combined axial compression + bending without early hinge formation, guiding ductility to beam spans.
β Boundary Supports & Reference Load Pattern
βΉοΈ The incremental plastic solver multiplies this reference load set by a proportional multiplier $\lambda$:
$\mathbf{F}(\lambda) = \lambda \cdot [q_{ref}, H_{ref}]^T$.

βοΈ Loading & Time-Dependent Concrete Creep
Implements the Age-Adjusted Effective Modulus Method (AEMM): E_c,eff = E_c / (1 + χ φ), accounting for long-term creep strain accumulation and stress relaxation.
