Minimum Thickness of Web in a Plate Girder:

Plate girders are commonly used in construction for building bridges, buildings, and other structures. The web of the plate girder is an important component that resists the shear forces and provides stability to the structure. The minimum thickness of the web in a plate girder depends on various factors such as the load, span, and the environment in which it is exposed.

Factors Affecting the Minimum Thickness of Web:

The following factors affect the minimum thickness of the web in a plate girder:

1. Load: The thickness of the web should be designed to withstand the maximum load that the structure will be subjected to during its lifetime.

2. Span: The span of the plate girder also affects the minimum thickness of the web. Longer spans require thicker webs to provide adequate stability.

3. Environment: The environment in which the plate girder is exposed also affects the minimum thickness of the web. If the plate is exposed to weather and other harsh conditions, it requires a thicker web to prevent corrosion and other damage.

Minimum Thickness of Web in a Plate Girder:

Based on the above factors, the minimum thickness of the web in a plate girder when the plate is accessible and also exposed to weather is 6 mm. This thickness provides adequate strength and stability to the structure while also resisting corrosion and damage from harsh environmental conditions.

Conclusion:

The minimum thickness of the web in a plate girder depends on various factors such as load, span, and environment. When the plate is accessible and also exposed to weather, the minimum thickness of the web is 6 mm. It is essential to consider these factors while designing a plate girder to ensure the safety and stability of the structure.
