ABSTRACT
This undergraduate project is a teaching building located in Nanjing Jiangsu. The total building area is 7345.8m2. The main structure is 7-storey framework. The height of 1st to 7th floor is 3.6m each layer. The height of ground floor is -0.6m.
This project consists of two parts. The first part is architectural design and another part is structural design. The main contents include graphic design, profile design, facade design of the building, structural arrangement, selection of the structures. The project also includes complete calculation of one unit of the building: load calculation, seismic force calculation, internal force calculation, combination of internal forces calculation, beam and column design calculation, reinforcement calculation. In addition to manual calculation, I also use PKPM series of structural design software to check.
Keywords: teaching building, reinforced concrete, frame structure

Chapter 1 Preface
This graduation design is the subject of teaching building in Nanjing, the structure form of the cast-in-situ reinforced concrete frame structure. This design aims to make use of most the professional knowledge through the four years stay in the University, making full use of the library, including a construction scheme and structure scheme of graduation design in modern network of existing resources to complete structure calculation, analysis of construction drawing, structure construction drawing and economic technology, a complete design task in English abstract content, so that we understand the general process of architectural design through the design, grasp all the content of architectural design, but also we can cultivate the comprehensive ability of using the basic theory and basic skills, ability of analyzing and solving practical problems and also learn a variety of graphics design software and office and other office software operation.
In the architectural design process, taking into account the fire safety requirements, to strictly comply with "fire standards" architectural design, consider building main function, practical, economical and aesthetic requirements, we must strictly comply with the requirements of "design of the building design standards"; in the structural design process, taking into account the earthquake we must strictly comply with the requirements, the structure arrangement “code for seismic design of buildings”, and take the calculation measures and some structure measures aiming at the structural characteristics of the design. Structural design is divided into two parts, one is the structure of the calculation part, the second part is the drawing.
The graduation project under the guidance of teachers, and combined with the characteristics of the design of the architectural design and structural design has been improved. In the calculation of the basic principles and concepts, to comply with the existing norms and engineering practice to complete.
More importantly, through this graduation project also allows us to study the knowledge of the University for a theoretical and practical integration, this is a specific application of the knowledge we have learned in the past four years, which will help us in the future.
Chapter 2 Structure selection and layout
This project is a practical application project of a teaching building in Nanjing, Jiangsu. The single-story building area of this building is about 1049.4, the main body is three spans and seven floors, and the building area is about 7345.8. Multi-layer reinforced concrete frame structure is required. Under normal circumstances, the reasonable design service life of this project is 50 years.
2.1 Geological conditions of the site
(1) The geotechnical engineering survey report was provided by a certain architectural design institute. According to the survey report, the proposed site has a flat terrain with a surface filled with miscellaneous soil, the following silty clay and clay; no liquefied soil layer distribution, stable groundwater level burial depth 1.65 -2.14m, non-corrosive to reinforced concrete.
(2) Detailed site investigation, Table 2-1
