According to the requirements of the assignment and the functions of the building, after consulting the relevant materials, it is finally determined that the building is a five storey reinforced concrete frame structure. According to the requirements of the assignment, the plan, elevation, section and other drawings of the building are designed with Tianzheng architecture software, and the reasonable column grid is arranged; The building area is 4320m 2， The building height is 17.85m, and the non accessible roof is adopted; Through the analysis of the building standard floor, the ⑤ axis frame is selected for manual calculation. Firstly, the material grade of beam, slab and column is selected, and the section size of beam, slab and column is determined according to the span and seismic grade, so as to calculate the lateral stiffness of a frame; Secondly, the vertical dead load and live load of a frame are determined according to the building practice and building function; Thirdly, the internal forces of a frame under horizontal load and vertical load are calculated respectively, and the internal force diagram is drawn; Finally, the load combination of the internal force of a frame is carried out to calculate the control internal force, and the reinforcement design of beam, slab and column is carried out with the control internal force, and the corresponding reinforcement is calculated and analyzed for the stairs and foundation.
