What Types of Foundations Are There for Steel Buildings?

There is an old saying in China that a tall building starts from the ground, and the foundation plays a decisive role in the building, especially for steel structures. The selection of steel structure foundations should be comprehensively considered from the following aspects.

1. Land survey

The steel structure foundation should be professionally measured on the land before construction, mark the level and check the soil quality. If the soil is relatively poor, it may cause the steel structure building to shift or sink. , It is recommended that you replace it with high-quality soil.

2. Load

Steel structure buildings have higher horizontal load requirements, that is to say, if the load is not good, the impact of natural disasters will be relatively large. For example, lateral forces such as strong winds and earthquakes may damage their structures, so steel structures Structural foundations need to consider the load problem.

3. Requirements

The steel structure foundation also needs to consider its basic requirements. Everyone knows that the foundation is divided into artificial and natural foundations. The steel structure foundation requires that one part of the building structure should not use artificial foundations, and the other part should use natural foundations. At the same time, it is not suitable to use two types or more. Large soil layer properties. If the soil condition is not good, the foundation should be deepened or the pile length should be increased to avoid uneven settlement.

The following are some common foundations types

1: Independent foundation, reinforced concrete structure, consisting of column base, cap, column body, column top plus embedded bolts or embedded steel plates.

2: Strip foundation, which is mostly suitable for large-span steel structure workshops, such as arched silos, etc. Strip foundation: Strip foundation is the most commonly used foundation form. When the previous independent foundation under the column cannot meet the requirements, You can use strip foundations.

3: The box-shaped foundation is composed of a reinforced concrete bottom slab, a top slab, and criss-cross internal and external partition walls. It is suitable for multi-storey steel structure factory buildings with heavy load and many equipment.

4: Raft foundation, suitable for high-rise steel structure workshops with larger loads.

5: Shell foundation, this kind of foundation is less, suitable for workshops with special equipment. This foundation is mainly used for the foundation of cylindrical structures at this stage.

6: Independent foundation: also known as "independent foundation", the most commonly used one is the foundation under the column.

7: Raft foundation: According to its structure, it can be divided into "beam type" and "slab type".

The help of a good concrete engineer is crucial when it comes to laying the foundation for your metal building.
