Reasons for Failure of a Web Plate
There are several reasons why a web plate may fail, one of which is yielding. Yielding occurs when the ratio of the clear depth to thickness of the web is less than a certain value.

Explanation of Yielding Failure
When the ratio of the clear depth to thickness of the web is less than a certain value, the web plate is more susceptible to yielding. This means that the web plate is more likely to deform plastically under the applied loads, leading to failure.

Clear Depth to Thickness Ratio
The clear depth to thickness ratio is an important factor in determining the stability and strength of a web plate. If this ratio is too small, the web plate may not be able to resist the applied loads effectively, resulting in yielding failure.

Consequences of Yielding Failure
Yielding failure of a web plate can have serious consequences, such as structural instability and potential collapse. It is important to design web plates with the appropriate clear depth to thickness ratio to prevent yielding failure.
In conclusion, the failure of a web plate by yielding is a critical issue that needs to be addressed in structural design. By ensuring that the clear depth to thickness ratio is adequate, the risk of yielding failure can be minimized, leading to a safer and more stable structure.
