What are the beam frame, barrel frame, dry column frame and dry well frame? How to distinguish?

Lifting beam frame: (stoplog) is a beam frame structure system, in which horizontal members are beams, vertical members are columns and beams are flexural members, and the building is stabilized by its own weight.

Barrel frame: ① Also called upright frame. (2) This structure is directly supported by short columns with dense column spacing and small column diameter, and the columns are connected by several purlins without beams, and the eaves are supported by cantilever purlins. (3) This structure is widely used in southern China, with the advantages of less materials and good wind resistance on the mountain surface. The disadvantage is that the indoor columns are dense and the space is not open. (4) Therefore, it is sometimes mixed with stoplog frames, which is suitable for different terrains, foundation members and column purlins.

Gan Lan style architecture: The stilts of Miao and Shui people in Guizhou belong to Gan Lan style architecture.

Dry frame: A building structure without columns and girders. In this structure, logs or rectangular and hexagonal wood are stacked in parallel on the upper floor, and the two ends of the wood cross at the corner to form four walls of the house, which are like wooden fences on ancient wells, and then short columns are erected on the left and right walls to form the house.
