Outline

• This web site provides the service to calculate section properties for I-section commonly used for beam structure.
• Japanese version and English version are available.
• As well as symmetric I-section, asymmetric I-section can be calculated too. However, web must be vertical and flange must be horizontal.
• Section properties for horizontal axis, vertical axis and main axis can be calculated at once.
• Section properties are calculated by input data of size of upper and lower flanges and web, in addition its cross section is drown. The cross section can be taken out as an image file.
• As calculation sheet of section properties can also be outputed as a text file, it is very useful to use as a part of the structure calculation sheet with a image file of cross section.
• Following section properties can be calculated.
• sectional area
• centroid
• moment of inertia
• section modulus
• incrinate angle of main axis
• radius of gyration
• Polar moment of inertia and shear center cannot be calculated. I expect to be able to calculate them in the future.
• Now, calculable shape is only the above I-section. But I will develop the program which can calculate the section properties of complex shape which has no limit in the number of components and can be contained shaped steels(by JIS Standard) as components. Perhaps after one year(or more?), I wish to open it in fee-based.
• Screen resolution to 1280 x 1080 or more is recommended.
