【Abstract】 :The design for the main structure of the programme in the framework of 9 horizontal axis the structural design of the framework. When the directions of the frames is determined, firstly the weight of each floor is calculated . Then, D value method to calculate wind loads under the structure of internal forces (moment, shear, axis of). Then the internal force (bending moment, shearing force and axial force ) in the structure under the horizontal loads can be easily calculated. After the determination of the internal force under the dead and live loads, the combination of internal force can be made by using the Excel software, whose purpose is to find one or several sets of the most adverse internal force of the wall limbs and the coterminous girders, which will be the basis of protracting the reinforcing drawings of the components. The design of the stairs is also be approached by calculating the internal force and reinforcing such components as landing slab, step board and landing girder whose shop drawings are completed in the end.
