Total Weight of the Tower
Unlock Audio Lesson
Let's start by discussing the total weight of the Eiffel Tower, which is an impressive 18,800 k. This weight is crucial for understanding how the tower is designed to support loads effectively.
What do you mean by total weight? Does it include everything in the tower?
Great question, Student_1! The total weight includes the actual structure of the tower itself and any additional loads like furniture and people. This total must be supported right from the base.
How does this total weight affect the design of the supports?
The supports must be strong enough to handle the total weight. We use a formula to calculate the stress and strain on those supports, ensuring they can carry the load without failing.
What happens if the weight is not properly calculated?
If the weight isn't calculated accurately, it can lead to structural failure. This is why engineers must adhere to strict design calculations.
In summary, we learned that the total weight of the Eiffel Tower is 18,800 k, which is fundamental in determining structural integrity and support design.
Distribution of Dead Load
Unlock Audio Lesson
In this session, let's dive into the distribution of the dead load. Not all parts of the tower experience the same load due to varying structures and designs.
How is the dead load actually distributed?
The dead load distribution can be illustrated using diagrams. For example, as we go higher, the load changes because it's based on the height and width at each section of the tower.
What does that mean for the lower parts of the tower?
Excellent point, Student_1! The lower sections endure more load since they support the entire structure above. Thus, they need to be more robust.
Why is it important to know this distribution?
Understanding this distribution allows engineers to optimize the material used, ensuring safety and stability. Even small changes can have significant impacts.
In summary, we covered how dead loads aren't uniformly distributed and how engineers account for varying loads at different heights.
Support Structures
Unlock Audio Lesson
Now, let's focus on the support structures that carry these loads. The Eiffel Tower has four inclined supports, each with a substantial cross-section.
What is the significance of having inclined supports?
Inclined supports help distribute the weight more evenly across the structure, preventing undue stress at any single point. This design enhances stability.
Does that change how we calculate loads?
Absolutely! The incline of the supports means that we need to take their angles into account when calculating load distributions and stresses.
So if one support failed, what would happen?
If one support were to fail, it could cause significant structural issues since the load would then need to be redistributed to the remaining supports.
In summary, we learned about the four inclined supports of the tower and their critical role in load distribution and structural integrity.

Quick Overview
Standard
The Eiffel Tower, with a total weight of 18,800 k, experiences different types of loads. This section describes the dead load distribution, emphasizing how the load varies across various heights of the tower and its supporting structure.
Detailed
Loads
The Eiffel Tower is a feat of engineering that supports a total weight of 18,800 k. It is essential to understand that the distribution of loads, particularly the dead loads, is not uniform. The varying diameters and heights of the structural components contribute to how the weight is supported. As illustrated in figures and calculations, the load distribution changes at different points of the tower.
For instance, the heights of the key platforms of the tower dictate how much load is acknowledged at those levels. The distribution must be calculated accurately to ensure the stability and integrity of the structure. Furthermore, the tower is supported by four inclined supports with a significant cross-section, designed to handle these loads efficiently, ensuring that the tower remains stable against various forces acting upon it.

The total weight of the tower is 18;800 k.
Detailed Explanation
This statement encapsulates the overall mass of the Eiffel Tower, measured in kilonewtons (k). The weight is a crucial factor in structural engineering, as it helps in determining how much load the supporting structures, like pillars and beams, need to bear.
Examples & Analogies
Think of the Eiffel Tower's weight like a stack of heavy books on a shelf. If the stack becomes too heavy for the shelf to support, the shelf may collapse. Similarly, engineers must ensure that the supports of the Eiffel Tower are strong enough to hold the tower's total weight.
Understanding Dead Load

The dead load is not uniformly distributed, and is approximated as follows, Fig. 30.3:
Detailed Explanation
A dead load refers to the static weight of the structure itself. In engineering terms, this weight does not change and includes the materials used in construction, such as iron and any other fixed installations. The phrase 'not uniformly distributed' implies that this weight is heavier in some areas than others, meaning that different parts of the tower will bear different amounts of weight, which is important to consider in the design phase.
Examples & Analogies
Imagine a backpack that has books placed unevenly. If all heavy books are concentrated in one part of the backpack, that area will sag more than other parts. Engineers must design the Eiffel Tower to ensure balanced distribution of weight to maintain stability, just like adjusting items in the backpack to carry it comfortably.
