IS 800 is a code of practice for general construction in steel. It provides guidelines for the design, fabrication, and erection of steel structures. In the case of a plate girder with vertical and horizontal stiffeners, the unsupported clear dimension of the web thickness tw should not exceed certain limits.

Guidelines for unsupported clear dimension of web thickness tw

The greater and lesser unsupported clear dimension of a web thickness tw should not exceed respectively:

- 270 tw: This is the maximum unsupported clear dimension for the greater dimension of the web thickness tw.
- 180 tw: This is the maximum unsupported clear dimension for the lesser dimension of the web thickness tw.

Explanation

The unsupported clear dimension of the web thickness tw is the distance between the stiffeners on either side of the web. The maximum unsupported clear dimension for the greater and lesser dimensions of the web thickness tw is specified in IS 800 to ensure that the web does not buckle under compression.

The limits specified in the code are based on the thickness of the web. The greater dimension of the web thickness tw is the longer dimension, and the lesser dimension of the web thickness tw is the shorter dimension.

Conclusion

In summary, according to IS 800, the greater and lesser unsupported clear dimension of a web thickness tw should not exceed 270 tw and 180 tw, respectively, for a plate girder with vertical and horizontal stiffeners. These limits are important to ensure the safety and stability of the structure.
