SecProps can calculate more than 50 section properties for Standard, Custom, Built-Up and General sections. It, also, can analyze a section for set of forces (forces & Moments along/around coordinate axes) and displays most of the stresses under that set of forces.
Steel Matrix: Calculating design capacities for a section. This includes the calculation of axial, bending, combined axial & bending, composite axial and composite bending capacities. Possibility of including web opening design, as well.
TribAreas: Calculated Tributary Areas for any irregular layout of Columns and Walls. Grouping is possible
