1. The frame column is composed of longitudinal frame to ensure the longitudinal stiffness of the steel structure workshop. Because the stiffness of the column outside the frame plane is much lower than the stiffness in the frame, the lateral stiffness of the column support is about 20 times times larger than that of the single column, so it is very effective to set up the column support to strengthen the longitudinal stiffness of the steel plant.
2. Bearing the longitudinal force of the Steel Structure workshop, the longitudinal braking force of the crane, the gable wind load, the longitudinal temperature effect and the earthquake effect are transmitted to the foundation.
3. To provide a reliable support for the frame column outside the frame plane, and to reduce the calculation length of the column outside the frame plane.
