It has all the merits of the office building in the aspects of product and service, as well as several advantages that the office buiding lacks. First, it can be used as either residence or office building,while an ordinary office buiding can only be used for business purpose. Additionaly,merceresidence building gains its advantage over office building in terms of price. It finds favour in the eyes of small and mediumsized enterprises with its price a little higher than resident building but lower than office building. This graduation project is an administration building , it was some of structural design that mainly carried on. The structural design expresses the thing that the engineer will express in structural language in brief. The structural language is structural elements simplified out refined from the building and other specialized drawings of structural engineer, including foundation, wall, column, roof beam, board, stair, fullpage proof detail picture, etc.. Then e to form the structural systems of the building or structures with these structural elements, including verticality and bearing and resist strength system of level, and then various load that situation produce in a most succinct way from transmission to foundation. The stage of the structural design can be divided into three stages on the whole: 1. Structural scheme stage: According to the importance of the building, providing fortification against earthquakes in the earthquake intensity, the geologic prospect
