steel structure workshop is widely used in coal engineering because of its light weight, excellent seismic performance, sensitive structure layout, fast processing and installation speed.When the construction of the steel structure workshop is finished, and the initial investment is not done well, then how can we prevent the steel structure workshop from sinking

　　The steel structure workshop foundation is generally selected as a separate foundation, which is planned according to the pressure of the migraine.Simply speaking, it is reinforcement. All steel structural columns are enclosed with I-beam or channel steel to form a network.

For the portal rigid frame steel structure workshop with low height and without crane, the connection between column base and base is generally planned as hinge joint.The top surface of the root is only subjected to the vertical pressure and the horizontal force caused by the wind load of the upper structure.The additional bending moment of the root bottom caused by horizontal wind load is small, and the root planning is relatively simple.

In order to effectively improve the lateral stiffness of the structure in order to control the lateral displacement, the column base is generally planned to be horizontally rigid and vertically hinged.

The longitudinal horizontal load of the powerhouse is transmitted to the top surface of the root bottom through the support between columns.In the transverse direction, because of the light weight of the steel structure, the long natural vibration period of the structure, and the relatively small horizontal seismic effect, the horizontal horizontal load for the control effect is generally the horizontal brake load plus wind formula of the crane, and the axial force of the two poles can not be equal.Based on the theory of elastic stability, the formula can be applied to two diagonal bars with the same length and section.

When we are in the construction of underground steel structure factory building, the steel structure manufacturer will do a good job to think about the countermeasures to prevent the factory building from sinking. Meanwhile, the construction personnel will timely find out the problems according to the environment and other factors, make rectification and ensure the construction quality.
