In summary, the conversation is about calculating the required thickness of a PVC false ceiling to prevent plastic deformation due to point loads distributed on it. It is recommended to seek guidance from a local Mentor for safety and learning purposes.

A false ceiling made of PVC is fixed around the edges. The ceiling has several point loads distributed on it. Given the ceiling dimensions, yield strength of PVC and the weights and locations of the loads, how do I calculate the required thickness of the ceiling to prevent it deforming plastically? (ignore thermal creep)
See attached sketch.

This type of thread is problematical because it involves the safety of the people who are standing under the ceiling, and because we cannot know everything about the situation. In general, if you have to ask these types of questions on the Internet, you probably should not be doing the project.

It is much better to find a local Mentor who can help you learn how to design and build such structures. They will be able to help you do the project safely, and learn how to do it on your own the next time.

Thread will remain closed.
 

1. What is the purpose of determining the thickness of supporting ceiling required?

Determining the thickness of supporting ceiling required is important for ensuring the structural integrity and safety of a building. It helps to determine the appropriate materials and construction methods needed to support the weight of the ceiling and any additional loads, such as furniture or equipment.

2. How is the thickness of supporting ceiling required calculated?

The thickness of supporting ceiling required can be calculated by taking into account the weight of the ceiling materials, any additional loads, and the span of the ceiling. Structural engineers use mathematical formulas and building codes to determine the minimum required thickness for different types of ceilings.

3. What factors can affect the thickness of supporting ceiling required?

The type of building, location, and intended use of the ceiling can all affect the required thickness. For example, a commercial building with a large open space may require a thicker ceiling to support the weight of heavy equipment or machinery, while a residential home may only need a standard thickness for the weight of furniture and occupants.

4. How can I ensure that the supporting ceiling is thick enough for safety?

To ensure the safety of a supporting ceiling, it is important to consult with a structural engineer or building code expert. They can assess the specific needs of your building and provide recommendations for the appropriate thickness of the supporting ceiling. It is also important to regularly inspect and maintain the ceiling for any signs of damage or wear.

5. Are there any building codes or regulations that dictate the thickness of supporting ceiling required?

Yes, there are building codes and regulations that dictate the minimum required thickness of supporting ceilings for different types of buildings. These codes are put in place to ensure the safety and structural integrity of buildings. It is important to consult these codes and regulations when determining the thickness of supporting ceiling required for a specific building.
