In order to calculate the section geometric properties of corrugated steel plate accurately and conveniently, the accurate calculation formulas of the section area, inertia moment, section modulus and turning radius of the corrugated steel plate per unit length are deduced through the definition of every geometric property. And the formulas are written as a "counter for section geometric properties of corrugated steel plate" program. Taking two corrugating forms as the calculation example, the calculation result of programming is compared with that of the existing literatures and CAD software. The results show that the calculation result is completely consistent with that of CAD software, and there are errors with that of the existing literatures which are the approximate values. It is concluded that the derived calculation formulas and the written "counter for section geometric properties of corrugated steel plate" program can accurately calculate the section geometric properties of corrugated steel plate.
