5.1. CROSS SECTION OF MASONRY WALL FOUNDATION, RCC COLUMNS WITH ISOLATED AND COMBINED FOOTINGS

Try these first

1. 1.

   What materials are used in masonry walls?

   Hint

   Think about the common building materials.

2. 2.

   Why do we use footings?

   Hint

   How would heavy weight affect the ground?

3. 3.

   What is an isolated footing?

   • Footing for multiple columns
   • Footing for a single column
   • Footing used in bridges

   Hint

   Remember what type of footing supports one structure.

4. 4.

   True or False: Combined footings are more economical when multiple columns are close together.

   • True
   • False

   Hint

   Consider the efficiency of material usage.

5. 5.

   Design a combined footing for two adjacent columns with different loads of 80kN and 120kN. Consider soil bearing capacity in your calculations.

   Hint

   Add the column loads and ensure footing dimensions are sufficient.

6. 6.

   Prepare a detailed AutoCAD drawing of an isolated footing based on given dimensions and reinforcement details.

   Hint

   Refer to your previous drafts on AutoCAD for guidance.
