Analysis setup

Analysis type Elastic modulus, E (MPa) Member area, A (mm²) Second moment, Iz (mm⁴) Lateral load per floor (kN)

Analysis has not been run.

Materials & section properties

Material preset Elastic modulus E (MPa) Density (kg/m³) Section shape Width b (mm) Depth h (mm)

Rectangular A and Iz are calculated for a solid rectangle. These are global screening inputs; they do not yet assign different properties to individual members or constitute a complete section library.

Load patterns

Load-pattern and combination definitions are saved with the project. The current prototype solver applies the lateral floor-load input as a single global-X load case; the editable pattern/combination factors are not yet assembled into separate solver cases.

Engineering status: Version 1.2.0 adds a sparse direct-stiffness assembly and iterative solution for a 3D spatial frame model with six degrees of freedom per node. This is still not an ETABS-equivalent solver: shell/wall/slab elements, diaphragms, modal/seismic analysis, nonlinear/P-Delta analysis, code design, load-combination solution cases and independently validated production-grade reporting are not implemented. Do not use this prototype for construction, safety-critical decisions or regulatory submissions.
