Why you have to use raft foundation?
A raft foundation, also known as a mat foundation, is a type of shallow foundation that is used in construction to distribute the weight of a building or structure evenly across a large area of soil. It is typically used when the soil's load-bearing capacity is relatively low, or when the building's loads are heavy and spread over a wide footprint. Here are some reasons why a raft foundation might be used: **Uniform Load Distribution**: Raft foundations are designed to distribute the load of a building uniformly over a larger area of soil. This helps prevent localized settlement that could occur with point loads or strip foundations. **Poor Soil Conditions**: If the soil at a construction site has low bearing capacity, meaning it can't support heavy loads without excessive settlement or deformation, a raft foundation can help distribute the loads over a larger area, reducing the pressure on the soil. **Variability in Soil**: In some cases, the soil properties might vary across the construction site. A raft foundation can help mitigate the effects of differential settlement, where one part of the building's foundation settles more than another due to varying soil conditions. **Heavily Loaded Structures**: Raft foundations are commonly used for buildings with heavy loads, such as multistory buildings, warehouses, or industrial facilities. The broad contact area with the soil helps prevent excessive stress on the ground. **Reduced Foundation Depth**: Raft foundations are shallow foundations, meaning they are located closer to the ground surface compared to deep foundations like piles or caissons. This can save excavation costs and make construction more efficient. **Economical Solution**: In some cases, a raft foundation might be more cost-effective compared to using deep foundations, especially when the structure's loads are spread out over a large area. **Stability in Poor Soil**: If the soil has a potential for lateral movement (such as in areas with high groundwater or seismic activity), a raft foundation can provide stability by distributing lateral forces over a larger area. **Preventing Differential Settlement**: In situations where multiple structures are built close to each other, a raft foundation can help prevent differential settlement that might occur if different structures have different foundation systems. It's important to note that while raft foundations offer several advantages, they might not be suitable for all construction scenarios. Factors such as soil type, building loads, local climate, groundwater levels, and structural design will all influence whether a raft foundation is the appropriate choice. Engineering professionals, including structural and geotechnical engineers, play a crucial role in determining the most suitable foundation type for a specific project based on site conditions and building requirements.
What is a downstand beam?
A downstand beam is a raft that consists of a supporting stand that takes the load of column or walls. The downstand beams is spread to the monolithically cast slab.
Locations of compression and tension in footing rebars?
Compression and tension occur in opposite side of the footing relative to position. So, at a spread ftg or pile cap, the top reinforcing will be in tension and the bottom compression. At the midspan, between spread ftgs or pile caps, the tension will occur in the bottom and compression in the top. Rebar lap splices usually occur in the compression points, so bottom lap at spread ftgs and top at midspans. Also, details will typical have additional rebar at the points of maximum tension so at the top over supports and bottom at midspans. This though should be confirmed with the Engineer of Record on any project, as assumptions can change project to project. But this is the general concept.
