In Nepal, the type of footing used in building construction depends on various factors such as soil type, structural design, and local construction practices. However, some common types of footings used in building construction in Nepal include:
A). Spread Footings: Also known as pad footings, these are shallow foundations that distribute the building load over a larger area of soil. They are commonly used for individual columns or wall foundations.B). Strip Footings: These footings are continuous concrete strips that support a load-bearing wall or line of columns. They are suitable for buildings with continuous walls or columns.
c). Combined Footings: These footings are used when columns are closely spaced and individual footings would overlap. Combined footings support multiple columns and distribute loads to the soil.
D). Raft or Mat Foundations: Raft foundations are large, solid slabs that cover the entire footprint of a building. They distribute the building loads evenly to the underlying soil and are suitable for areas with poor soil bearing capacity or where differential settlement may occur.
E).Pile Foundations: In areas with weak or compressible soil, pile foundations are used. These consist of long, slender columns driven deep into the ground to transfer building loads to deeper, more stable soil layers or bedrock.
The choice of footing type in Nepal is influenced by factors such as seismic activity, soil conditions, and structural requirements. Builders and engineers typically assess these factors during the design phase to determine the most appropriate footing type for a specific building project.
