Steel Frame — Self-Weight + UDL

Symmetric rectangular portal frame (4 m columns, 6 m beam) with column self-weights, beam self-weight, and a 10 N/m UDL; symmetric loading splits reactions 380/380 N, and columns carry pure axial compression with zero shear.

All reaction values are computed by the StatIQ structural engine, not generated text. Signs follow the solver's convention: a positive R_y acts upward, a negative R_y downward; a positive M is counter-clockwise.
