A simple personal understanding is to transfer load and connect, usually expressed as KFZ, and generally made of H-shaped steel.

‌Wind columns are usually installed in the gables at both ends of the house structure and are mainly used to resist horizontal wind loads‌. This kind of structural column is generally used for high-rise brick-concrete structures with large internal spaces and few horizontal walls, such as industrial plants and large warehouses.

The main function of the wind-resistant column is to resist horizontal wind loads, and is connected to the steel beams through hinge nodes to transfer the wind load to the roof system and then to the entire rack load-bearing structure. The connection method between the wind-resistant column and the foundation can be rigid connection or hinged connection. The specific arrangement will affect its stress state and the type of load transmitted.
