Public buildings Outdoor space environment art
Public buildings The form and space of the building are two contradictory aspects in the architectural plastic arts. They are interdependent and inseparable. The artistic form of the external form of public buildings cannot be separated from the principle of unity and change in composition. In composition, attention should be paid to the relationship between "principal and subordinate relationship, contrast and coordination, balance and stability, rhythm and rhythm". Common prosodic techniques include continuous rhythm, gradual rhythm, undulating rhythm, staggered rhythm (Germany Pavilion of Barcelona Expo), etc.
Technical and economic problems of public buildings
The composition of building space and shape should be based on certain engineering and technical conditions. The space requirements of architecture and the development of architectural technology are mutually reinforcing. The selection of technical form shall meet the functional requirements and conform to the economic principle.
Public building and structural technology
There are three common structural forms of public buildings: hybrid structure, frame structure and spatial structure.
Hybrid structure
Public buildings It is usually a brick wall and reinforced concrete beam slab system. The beam slab span is small, and the plane of the load-bearing wall is arranged in a rectangular grid. It is suitable for buildings with small rooms and few floors (such as schools, office buildings, hospitals). The load-bearing wall shall be as uniform and circular as possible, with upper and lower layers aligned. The size of the opening is limited, and the height thickness ratio of the wall shall be reasonable. The large room shall be on the top and the small room shall be on the bottom.
