calculation of nearly all 2d structures (we calculated systems with more than 30 elements) global moment and shear hinges different supports (fixed, hinged and moveable in various directions) global node loads local and global trapezoidal element loads fast calculation routine graphic input via dialog boxes graphic output of the results for the whole structure graphic and numerical output of the results for each element
