Several principles to choose which type building structure
(1)To meet the requirements of building function
For some public or commercial buildings, the function of visual requirements, such as: the stadium to ensure good visual effect,no column can be set in the game hall, must used large span structure; large supermarket to meet the shopping needs of indoor space with mobility and flexibility, it should adopt the steel frame structure.
(2)To meet the needs of building modeling
If the plane and elevation of the building structure is a special type of selection,or building modeling complex,according to the actual need,we should set the appropriate parts of the earthquake proof joints,then come into being a more regular structural units.
(3)To give full play to the advantages of the structure itself
Each structure has its own characteristics and shortcomings, has its own scope of application, so to combine the specific circumstances of architectural design for structural selection.
(4)To consider the conditions of materials and construction
Because of the different materials and construction technology, the structure forms is also different. For example: masonry structure materials used as materials, the construction is simple, suitable for low layer, multilayer steel structure. When the steel supply shortage or unperfect steel processing and construction technology, can not be used in a large number of steel structure.
(5)To reduce the cost as much as possible
When several structural forms are possible to meet the architectural design conditions, the economic conditions are the decisive factors, as far as possible to reduce the cost of the structure of the structure.
