Floor Loading - Bending Moment?

In summary, the person is trying to find the bending moment on beam CE in a problem with loading from three floor slabs. They are struggling to calculate the maximum bending moment at mid-span due to the non-uniform distribution of the two smaller slabs. They have attempted to use the equation M=(FxL)/2, but have not been successful in finding the bending moment.

Homework Statement



I'm trying to find the bending moment on beam CE in the attached problem. There is loading from all 3 floor slabs. I'm struggling to figure out the maximum bending moment at mid-span because the 2 distributed loads from the 2 smaller slabs are not uniform as such

Obviously there is the reaction force minus the udl from the top slab, just struggling to work out what the BM is from the triangular load.: +(152×4)-(20×4×2)-?

Homework Equations M=(FxL)/2 The Attempt at a Solution I tried to add the two distributions together, as well as break it down into individual forces, but I just couldn't figure out how to calculate the BM
 

1. What is floor loading and how does it affect bending moment?

Floor loading refers to the amount of weight or load that is placed on a floor surface. This load can affect the bending moment of a floor, which is the amount of force applied to a floor that causes it to bend or deform. The greater the floor loading, the greater the bending moment will be.

2. How is floor loading calculated?

Floor loading is typically calculated by dividing the total weight or load on a floor by the total area of the floor. This will give you the amount of weight per unit area, also known as the floor load capacity. It is important to consider the type of flooring material and its maximum load capacity when calculating floor loading.

3. What factors can affect floor loading?

There are several factors that can affect floor loading, including the type of flooring material, the design and construction of the floor, the distribution of weight, and the type of load being applied. Other factors such as vibrations, temperature changes, and moisture can also impact floor loading and should be taken into account.

4. What are the implications of exceeding the floor load capacity?

If the floor load capacity is exceeded, it can lead to structural damage or failure of the floor. This can result in costly repairs, safety hazards, and potential collapse of the floor. It is important to always stay within the recommended floor load capacity to ensure the structural integrity and safety of the floor.

5. How can floor loading be measured and monitored?

Floor loading can be measured using specialized equipment such as load cells, pressure sensors, or strain gauges. These devices can provide real-time data on the amount of weight being applied to a floor. Regular monitoring of floor loading is important to ensure that it does not exceed the recommended capacity and to identify any potential issues before they become major problems.
