Geometric data of cross-sections of beams

ABSTRACT

This paper describes a program which calculates the geometrical characteristic values of cross-sections of beams with complex shapes (bars or thin-walled profiles with any number of holes in the profiles).After a short introduction describing the calculations involved for moments of area, we will introduce the capabilities of every component of this program and we will make a survey of the whole system via flow chart.At the end of the paper we will summarize the main features of the program and mention some possible extensions.
