structural analysis of shanghai himalaya art center abstract: zenda himalayan art center is composed with some unique bionic(tree-imitating) buildings that are rarely built in china. some analysis methods and seismic measurement based on the specialties of the structural design are introduced in the article. they introduce construction technology of tube reinforced concrete structures with bionic space variation abnormal surface from location , formwork and support system selection and concrete construction. the structural design of the project could provide certain reference function to similar projects in the future.key words: bionic architecture; special shaped tube; fluid structures; seismic designdevelopment of building shows a complex contradictory forms of exercise. the basic purpose of the building - the use of space which has a function determines the materiality of the building, must be tangible. the building material, structure became necessary means to achieve this purpose. the relationship between means and ends, the form and content of this as the origin, staggered linked together. while part of the building also need to take spiritual metaphysical aesthetic needs, the three-level building technology aesthetics began.shanghai himalaya art center facadesshanghai himalaya art center renderingsshanghai zenda himalaya art center project is located in the plum intersection, fang dian road, pudong new area, shanghai, with a total construction area of about 160,000 square meters, 3 basements. building above ground is composed of three parts, the office, contemporary art center and a five-star hotel , with building length of 210m, a width of 60m. among them, the office is eight-storey, roof structure elevation 61.5m; the five-star hotel is 17 floors, with roof structure elevation 95.7m; contemporary art center roof structure elevates 31.5m, part elevation of 37.1m.shanghai himalaya art center takes a reinforced concrete structure. the most notable is the unique design of the central special shaped tube, including museum of contemporary art, childrens museum of art, the museum of art and experimental theater, an area more than twenty thousand square meters.this part of the unique organic shapes uses the optimization techniques structural evolution (eso method) to design. this computer-aided method uses a computer to control all forms of irregular space volume, automated form shape according to the conditions and mechanical design conditions and make adjustments. costing a minimum of material to form a reasonable structure can be achieved by it.seo methods ensure the implementation and use of the final design of the form completed on the construction drawings. eso method, as a design method, achieves the dual purpose of arts centers function features and spiritual aesthetic, is the bridge of the unity of the form and content.the final three-dimensional model by computer-aided design the final middle part , which is achieved combined with computer-aided design, has been a bionic building which is similar to roots and its vertical components consists of special cylinder-shaped .layout of planeelevations and sectionsits plane is made by a 29 fluid, of which 23 belong to art center and hotels and office buildings both have three of them. horizontal section of each seat fluid is irregular closed curve, for example as 3 floors underground, horizontal section 3.10 24.0m long, 1.70 9.30m wide, total height of 47.60 53.20m, which the 0.000 -16.100m part of is the underground part, 0.000 37.100m for the ground segment. in elevation 5.4,10.8m setting two mezzanine, which is a partial floor, is an art exhibition hall. elevation of 16.200m for the whole floor slab is 2,000-seats multi-function hall (and theater). the whole group was root-like fluid. covering the fluid group is curved arched roof, which is reinforced concrete shell structure. renderings details of art center art center interior renderingsconsidering the specific seismic load in the building design, bionic construction use 27 special shaped tube and the slab between them to form the inter-shaped shear wall system (bionic structure), with the shaped tube suffering the whole load and lateral pressure. and in the case of a constant earthquake , put relative deformation between layers under control by 1/1000 . for smaller barrel-shaped tube, they were reviewed by the seismic requirements for columns at the same time.to reduce twisting of structure, the thickness of special shaped tube varies depending on the distribution of the stiffness of the plane, taking 220 to 600. contact slab with barrel-shaped beam to form integral structural rigidity between special shaped tubes. set wide flat beams around the floor, within the floor mainly is flat slab structure, thickness of 250 to 400, the most of 600.roof is curved arched roof consisting of plate with a certain slope, span of 40 meters. it is designed to strengthen the reinforcement of slab surrounding arch, put amount of prestress to form the constraint of arch sheet. to alleviate the roof load, roof greening uses lightweight nutritive soil.setting up slab in special shaped tubes is by layer(used as equipment rooms), the interior of which can not set slab in is added internal haunched plates, which can provide a supporting and stabilizing effect for tubes.concrete construction diagram of fluid buildings conclusionthe bionic building gradually been widely adopted in modern urban construction. the shanghai zenda himalayas art center which has been finished, following the birds nest, water cube, is another architecture example of bionic art in our country. it has unique architectural style and the singular form, using group of reinforced concrete tube structure which surfaces is varied and shaped in space, fully expressing bionic image of clusters of roots. this bionic structures has not been reported in similar projects at home and abroad, and its successful completion shows that our level of construction and designing in the area has
