摘 要
本次毕业设计题目为博爱县第二中学办公楼设计，结构形式为钢筋混凝土框架结构。共8层，层高均为3.4m。建筑物总长度为57.6m，宽度为16.8m，高度为27.17m，建筑总面积约为7257.6m2。框架抗震等级为二级，抗震设防烈度为7度。本设计的主要内容：
建筑设计：根据使用功能不同，分别设置了卫生间和办公室宿舍。并设置两部电梯，电梯两侧布置两个防火楼梯，卫生间在楼梯间两侧，每层设置。该方案，结构布置合理，功能明确， 由于本建筑平面长度较长，故设置抗震缝。
结构设计：结构设计阶段进行了结构平面布置、估算截面尺寸、荷载计算、框架计算、侧移验算、内力计算、内力组合及构件设计等工作，并完成了标准层结构平面布置图、框架配筋图、楼板配筋图、楼梯配筋施工图。内力计算：采用底部剪力法进行水平地震作用下的楼层内力计算；采用D值法进行水平地震作用下框架内力计算；采用弯矩二次分配法进行竖向恒载、活载作用下的内力计算；内力组合：考虑恒载＋活荷载、恒载＋活荷载+水平地震作用两种内力组合方式进行框架梁、柱的最大弯矩及轴力计算；截面配筋及验算：对于框架梁柱进行控制截面的计算配筋，并进行框架节点的验算。双向板设计采用塑性理论的计算方法进行计算配筋。

Abstract
The design title is the Office Building design of the second middle school in Boai county , whose structural form is reinforced concrete and frame structure. The building has 8 layers and the height of each layer is 3.4 meters. The total length of the building is 57.6 meters and the width is 16.8 meters.. The total height of the building is 27.17 meters. The building area is more than 7257.6 m2. The structure can resist secondary earthquake. The earthquake intensity is 7 degrees. The primary design contents are as follows:
Architectural design: According to the functions of use，the building has some office rooms and toilets . There are two elevators in the hall, and there are two fire-escape stairs at the both sides of elevator. The bathrooms are at the both sides of fire-escape stair, they are set up in each floor. The structural layout of building is reasonable, and its functions are clear. Because this architectural plane length is long, the movement joint has been established.
Structural design: The structural plane layout, the preliminary estimation of section size, the computation of load, the computation of frame structure, the checking computations of sideway, the computation of internal force, the combination of internal force and member design and so on are done in the stage of structural design. The structural layout of typical floor, the reinforcing drawing of frame and the reinforcing drawing floor board and stair have been completed. Internal force computation: The internal forces of floor are calculated under the horizontal earthquake by the bottom shearing force method. The internal forces of frame are calculated under the horizontal earthquake by the “D” value method. The internal forces under vertical dead loading and live load are calculated by the allocating bending moment. Combination of internal force: Considering that combination of the dead load and live load, combination of the dead load and live load and horizontal earthquake function, we calculate the biggest bending moment and the axial force of beam and column. Section reinforcing and checking calculation: the control sections of the beam and column are reinforced, and the frame nodes are checked. The bidirectional boards are reinforced by the plastic theory.
Keywords: architectural design, frame structure, reinforcing design, earthquake-resistance design
