This building is five layers, total height 22.8 meters, the elevation difference of inside and outside of 0.45 meters, 0.9 meters high parapet. Building a total length of 58.2 meters, a total width of 15 meters. The engineering structure design adopts multi-layer reinforced concrete frame structure, basic steps as follows: the determination of structure calculation diagram; The load calculation; The internal force analysis; Internal force combination; Beam and column section reinforcement, the board design, the design of stair, basic design and structure of the construction drawing, etc. Among them, the internal force calculation, consider the following four kinds of load is constant load and live load, wind load and earthquake action; The design of the column, the board by using elastic theory; Beam design adopts the theory of plasticity; Stair chooses plate stair; Selects the cross bar basis. When making section seismic design, following the strong shear weak bending, strong column weak beam, strong node weak component design principle, and satisfies the requirement of construction. This engineering structure form for reinforced concrete frame structure, design, strictly abide by the current specification including the ? building foundation design code ?, ? load code for the design of building structures reinforced concrete structu
