Structural Sizing Sanity Checker

Run preliminary structural sizing and sanity checks on beams, columns, and simple members: estimate loads, check span/depth, bending, shear, deflection, and member capacity to catch obvious problems early - for concept design and reviewing someone else's numbers. Use when the user wants to "size a beam/column", "is this member big enough", "rough structural check", "load takedown", "deflection check", or "sanity- check this design". Preliminary only; a licensed PE stamps all real structures.
