A Design of library in A university in Hefei Abstract This graduation design topic is a design of library in a university in design consists of architectural design and structural design. The form of the main structure is the frame structure of cast-in-place reinforced concrete, with the total length of , the wedth of , the height of , and the total built-up area of . The building has five stories and the height of each story is . The size of memeber is first estimated, the gravity load is calculated, then the period of libraton is calculated with the vertex displacement method; the force of earthquake action is calculated with the base shearing force method; the structural internal force under horizontal load is estiamted with the D value method; the structure internal force under the vertical load is adopted to calculate with the bending moment secondary distribution method, and then the Endogenic force combination is carried in structural calculation. The most unfavorable combination of frame beam and column section of reinforcement is selected to calculat. Finally the calculation of reinforcement of Floor slab, Board type stair and Benched and detached foundation is carried.
