Foundation Design
The engineering discipline focused on creating stable structural supports that transfer building loads safely to the ground while accounting for soil conditions, environmental factors, and construction requirements.
Foundation Design
Foundation design is the critical engineering process of developing load-bearing structures that serve as the interface between buildings and the earth beneath them. This fundamental aspect of construction requires careful consideration of multiple factors to ensure structural integrity and longevity.
Core Principles
The primary objectives of foundation design include:
- Load distribution and transfer
- Settlement control
- Stability assurance
- Environmental adaptation
- Cost effectiveness
Types of Foundations
Shallow Foundations
- Spread Footings - Individual column or wall supports
- Strip Foundations - Continuous support under walls
- Raft Foundations - Single continuous foundation supporting entire structure
Deep Foundations
- Pile Foundations - Transfer loads to deeper, stable soil layers
- Caisson Foundations - Large diameter deep foundations
- Pier Foundations - Intermediate depth solutions
