Steel Design: GEOMETRICAL PROPERTIES

 

 

The geometrical properties, as detailed in Cl. 3.6 of IS 800:2007, of the gross and the effective cross-sections of a member or part thereof, shall be calculated on the following basis: a) the properties of the gross cross-section shall be calculated from the specified size of the member or part thereof or read from appropriate table b) The properties of the effective cross-section shall be calculated by deducting from the area of the gross cross-section, the following:

 

     The sectional area in excess of effective plate width, in case of slender sections.

 

         The sectional areas of all holes in the section except for parts in compression. In case of punched holes, hole size 2 mm in excess of the actual diameter may be deducted.
