Visual C++-Based Algorithm Research and Software Development for Cold-Formed Thin-Wall Steel Sectional Properties of Arbitrary Section

Abstract:

Current steel structure design software cannot calculate sectional properties of user-defined section of cold-formed thin-wall steel accurately. Since the sectional properties data given by design code has been implanted into corresponding modules of these software and the software disregard the radian of corner of steel, erroneous results will be generated if the user-defined sectional size doesn't match the sectional size of the data file implanted. According to Green's theorem, the author derived precise formulas for sectional properties of arbitrary section and developed software for calculation based on Visual C++ platform. The software which can calculate exact solution of sectional properties of arbitrary section has been verified by comparing results from various methods. This software can be used independently as a calculating tool and the calculation module can be implanted into other steel structure design software to make calculation for sectional properties of arbitrary section possible.
