Properties of ISHB

Dear Readers,

This is continuation with my earlier post unit weight of ISHB, self would like to post the sectional properties of ISHB. My earlier post, Unit weight of ISMB has been one of the popular posts. In the same way, I am expecting this post would be a next popular post and also helpful to all engineers.

Properties of beams are having two parts. One part is Physical dimensions and another part is sectional properties of Beam. Basically dimensional part contains depth and width of section, Thickness of Web and Flange and Root Radius. Where as sectional properties contains Moment of Inertia, Radius of Gyration and Section Modulus. These are useful for design engineers.

Unit Weight of ISSC

SC Series is called Column Sections

      In continuation with my earlier posts ISMB, ISJB, ISLB, ISWB & ISHB this is also one of the standardized categories of hot-rolled steel, shaped H-beams.

1. ISSC 100 X 100 - 20.00

2. ISSC 120 X 120 - 26.20

3. ISSC 140 X 140 - 33.30

4. ISSC 150 X 150 - 37.10

5. ISSC 160 X 160 - 41.90

6. ISSC 180 X 180 - 50.50

7. ISSC 200 X 200 - 60.30

8. ISSC 220 X 220 - 70.40

9. ISSC 250 X 250 - 85.60

        When Comparing with ISHB & ISSC the main difference is Height & Width of beam is equal.  In addition to above sizes some special sizes also available in market. ISSC 152 X 152 - having unit weight 23 Kg & 30 Kg per Meter. Another is ISSC 204 X 204 having unit weight 49.9Kg per Meter

Difference Between "I" Beam & "H" Beam

From the previous posts, all you may be familier with "I" Beam & "H" Beam. Let us see what is the difference between them.

Both are structural beam of rolled steel having a shape whose cross section resembles the letter H; and Letter I (an ‘H’ Turned through 90 degree). The H-beam has relatively wider flanges than the I beam, however an "I" beam has tapered edges towards the centre rib called Web.

 
It is the difference between the widths (Flange) by height (Web) ratio. In the case of H beams the width of the flange would be equal to or more than the height of the cross section. In the case of I section, the height of the cross section would be higher than the width of the flange.

In general H-beams are better than I-beams are very subjective. Since they are usually heavier and weight per running meter also more.


However it is most important to use the optimal beam configuration for the application. While selecting the beam, the thickness of the centre web is most important since this is what takes the brunt of the force. Good construction demands structural beams that more than carry maximum loads including factor of safety while using the minimum weight of steel.

Unit Weight of ISHB

Indian Standard Heavy Weight Beams / Columns

In continuation with my earlier posts ISMB, ISJB, ISLB & ISWB this is also one of the standardized categories of hot-rolled steel, having a shape whose cross section resembles the letter H.

It is having the sizes from 150 to 450mm. Usually they are heavier sections.It is available in two weights (Type-I & Type-II). Please refer the table below.
       In addition to above ISHB 150 X 150 is available for unit weight of 27.1kg Web thickness is further lesser than type-II

       For Type-I & II, these heavier beam sections in each size are obtained from the same set of rolls. The width of flanges and Height of Beams are same , However the difference is between the thicknesses of the webs. Therefore, while ordering these heavier sections, mass should be mentioned. Please note that ISHB sections are also used as column sections.
