Building structure can be divided into several categories?

Building construction can be divided into several categories?

First, based on the characteristics of the building constructed in the shape classification
(1) single-layer structure (1 to 3 layers, and more for single plant, canteens, theaters, warehouses);
(2) multi-layer structure (2 to 6 layers);
(3) high-level structure (typically 7 or more layers);
(4) large-span structures (a span of 40 ~ 50m).
Second, the material structure according to the classification used
(1) reinforced concrete structure;
(2) masonry construction (brick, stone masonry, small block, big block, brick masonry);
(3) steel structure Foshan Steel;
(4) wooden structure;
(5) plastic construction;
(6) film inflatable structure.
Third, the main structure of the building constructed in accordance with the classification of the form
(1) wall structure (to the wall as a support level and assume a horizontal force component structure);
(2) frame structure (beams and columns rigidly connected by a skeleton structure);
(3) Frame - shear (shear wall) structure;
(4) shear structure (wall Jicheng came when the horizontal component of vertical load, but also bear the force of wind and seismic horizontal load coming);
(5) cylinder structure (composed by the shear wall or frame tube composed of dense columns);
(6) truss structure;
(7) vaulted structure;
(8) grid structure (to do the roof truss);
(9) space thin-walled structures (including the shell, folded plate, episodic structure);
(10) cable structure (suspension structure to cable or steel rod as the main load-bearing components).
