ABSTRACT
This project covers area of 1154.40 square meters and contains six floors. The total area of the building is 6155.34 square meters.Its total building height is 25.23 meters. the outdoor ground is -0.45 meters lower than the indoor. The column spacing is 6 meters.depth of the room are 7.2 meters.The storey of the first floor are 4.5 meters and the standard layer are 3.9 meters. The roof walls are 0.9meters height. The building are 54.65 meters total in length and 18.65 meters total in width. The design of this building is regular shape in exterior. With the outside wall ceramic tile porcelain.and the roof walls built by aerated concrete block. The structure is used with plastic-steel windows and doors except for bathroom.
The structural form of the civil project is the form of reinforced concrete frame structure and structural layout rules. Structural arrangement include main beam and secongary beam. The load path is reasonable .The strength degree of frame columns is C30.And the cross sections of the columns are 650mm×650mm.The strength degree and the cross sections of the frame columns have no change along the height. The strength degree of the frame beams is C30, and the main beam is 350mm ×700mm.secondary beam is 250mm ×500mm. the size of frame beam is same as main beam is 350mm ×700mm.Considering the basement raft foundation is adoptted, the strength degree of which is C30. The soil condition of the building site is good enough. Choose the independent under column foundation with the concret of C30.The stairs is designed plate stairs.
Structure calculation include internal force on braced frame seismic behavior;combination of internal forces ;section design of beams and columns;basis design and stairs design.At lsst draw the working drawing with the professional software.include architectural and structural drawing.
The design is strictly complied with the current code of our country . The calculation includes the load. the composition of internal forces. the design of foundation and the design of the stairs.
Key words： Architectural design；Structural arrangement ；
