The project is a reinforced concrete frame construction office building, which contains 5 floors. Each floor's height is 3.6 meters . The whole elevation is 19.6 meters. In this area, the intensity of earthquake resistance is 7. The basic wind pressure is 0.75 kN/m2.The location type of the constructs is II. It has finished some assignments as follow : (1) the architectural design, (2) structure type choosing, (3) board structural design, (4) frame construction design, (5) foundation structural

... design, (6) staircase design and so on. Among them, It used the theory of plastic in the design of the floors and elasticity in the design of roof. When calculated the frame's cryogenic force under the vertical load function, It used the lamination calculation method. D method is used in the calculation of frame cryogenic force under the horizontal load function. In the design, the board's thick is 100mm, the beam's size is 250mm×450mm, the size of the calumniation is 500mm×500mm. It has used the reinforced concrete step-shape independent foundation, which is 0.6m height, and buried 1.5m depth. The analyzing process of some typical members of the structure were showed in the paper.
