If the foundations of all the columns of a structure are designed on the total live and dead load basis, then A. There will be no settlement of columns B. There will be no differential settlement C. The settlement of exterior columns will be more than interior columns D. The settlement of interior columns will be more than exterior columns

The correct answer is: B. There will be no differential settlement.

Differential settlement is the uneven sinking of a structure’s foundation. It can cause cracks in the walls and floors of a building, and can even lead to the collapse of the structure.

When the foundations of all the columns of a structure are designed on the total live and dead load basis, the columns will be able to support the weight of the structure evenly. This will prevent differential settlement and ensure the safety of the structure.

Option A is incorrect because even if the foundations of all the columns are designed on the total live and dead load basis, there is still a possibility that the columns will settle due to other factors such as soil conditions.

Option C is incorrect because the settlement of exterior columns is not necessarily more than the settlement of interior columns. The settlement of columns depends on a number of factors, including the type of foundation, the soil conditions, and the load on the column.

Option D is incorrect because the settlement of interior columns is not necessarily more than the settlement of exterior columns. The settlement of columns depends on a number of factors, including the type of foundation, the soil conditions, and the load on the column.
