For steel works, the design of the foundation dictates the rest of the planning and construction process, and is therefore committed before the actual engineering building is built. During the planning process, it is important to note the following important factors affecting the foundation design.
1. Land Survey
Before the construction process begins, the land must be professionally surveyed and marked for levelling. Also need to know the boundaries of the plot. The measurement of the land will greatly affect the design of the foundation, as will the soil quality. The soil is graded according to the height and conformation of the land as marked by the surveyor's stake. Regardless of foundation design, loose soil can cause steel buildings to move and sink. It is necessary to carry out foundation treatment such as vibrating method, sand pile compaction method, and dynamic compaction method.
2. Air Suction
Columnar uplift occurs when strong winds create a suction effect that pulls steel structures up from their foundations. The columnar uplift of the steel structure is very dangerous, and the prevention of the columnar uplift should start from the foundation. Higher density foundations or deeper foundations are options to reduce columnar uplift in steel structures.
3. Load
Steel structures tend to have higher horizontal loads, which means they are more susceptible to lateral forces such as strong winds and earthquakes. Forces like this can even cause entire engineering structures to overturn or slip from their foundations. The foundation can help distribute or resist the high level of column reaction of steel engineering buildings by connecting steel tie rods with high-strength bolts to the foundation or increasing the size of the foundation, but the latter may result in higher costs.
Conclusion
As mentioned above, it can be known that the design of the foundation is determined by the land, the load and the wind lift of the steel structure engineering building. Usually a freestanding foundation is used. As mentioned above, it can be known that the design of the foundation is determined by the land, the load and the wind lift of the steel structure engineering building. Usually more free-standing foundations and pile foundations are used. The role of the foundation is to serve as a pillar for anchoring engineering buildings and to provide stability and strength. Then when these factors are taken into account and there are many pile foundations, the role of the foundation is to serve as a pillar to anchor the engineering building, and to provide stability and strength. Then, considering these factors, it should be based on the foundation. It is crucial to design a suitable foundation accordingly for the steel structure project.
