Explanation:
The foundation of a structure plays a crucial role in ensuring its stability and longevity. When designing the foundation of a structure, it is essential to take into account the total live and dead load that it will be subjected to over its lifetime. Here are some key points to understand why the settlement of exterior columns will be more than interior columns if the foundations of all the columns of a structure are designed on the total live and dead load basis:
1. Definition of total live and dead load: The total load that a structure will be subjected to over its lifetime can be divided into two categories - dead load and live load. Dead load refers to the weight of the structure itself and any permanent fixtures, such as walls, floors, and roofs. Live load refers to the weight of people, furniture, and other movable objects that will be present in the structure.
2. Designing foundation on total live and dead load basis: When designing the foundation of a structure, engineers typically take into account both the dead load and live load that the structure will be subjected to. This ensures that the foundation is strong enough to support the weight of the structure and any additional weight that may be added over time.
3. Settlement of columns: Settlement refers to the sinking of a structure or its components into the ground over time. Settlement can occur due to a variety of factors, including soil conditions, water content, and the weight of the structure itself.
4. Differential settlement: Differential settlement refers to the uneven sinking of different parts of a structure. This can occur when one part of the structure is subjected to more weight or pressure than another part.
5. Exterior vs interior columns: Exterior columns are typically subjected to more weight and pressure than interior columns. This is because exterior columns have to support the weight of the structure as well as any additional weight from wind, rain, and other environmental factors. Interior columns, on the other hand, only have to support the weight of the structure itself.
6. Conclusion: If the foundations of all the columns of a structure are designed on the total live and dead load basis, the settlement of exterior columns will be more than interior columns. This is because exterior columns are subjected to more weight and pressure, which can cause them to sink more quickly than interior columns.
