Types of foundations include shallow, deep, and special foundations.

• Shallow foundations: spread footings, mat foundations

• Deep foundations: piles, drilled shafts

• Special foundations: caissons, cofferdams

Shear and bending moment diagrams show the variation of internal forces along a beam.

• Shear diagram shows the variation of shear force along the length of the beam.

• Bending moment diagram shows the variation of bending moment along the length of the beam.

• Shear force changes sign at point of concentrated load or reaction.

• Bending moment is zero at points of concentrated load or reaction.

Yes, DPC (damp proof course) is required in boundary walls to prevent rising damp.

• DPC is necessary to prevent moisture from rising up through the walls.

• It helps in protecting the structure from dampness and water penetration.

• Common materials used for DPC include bitumen, plastic sheets, and chemical compounds.

• Proper installation of DPC is essential to ensure its effectiveness in preventing dampness.
