摘   要

本设计为5层框架结构教学楼，总建筑面积约4665m2,主体结构高度约19.8m。地处7度抗震设防区域，场地土类为2类。结构设计是本设计的重点。本设计的计算内容主要有：结构设计方面：先根据轴压比确定柱和墙的截面尺寸及梁跨度估算梁板截面，计算出各构件的几何特征值和结构体系刚度特征值；然后对单，双向楼板进行内力计算和配筋；其次是按其分配墙所受的水平荷载作用，计算建筑物的自重质量。用D值法计算水平风荷载和地震作用下的内力和位移（其中用底部剪力法计算地震作用，本建筑物的质量和刚度沿高度分布比较均匀、高度为17.7m<40m、以剪切变形为主，所以适用于底部剪力法计算地震作用）。计算出建筑物在竖向荷载作用下产生的内力。思路是计算结构横方向的总抗侧刚度，计算结构基本自振周期，计算在水平荷载下产生的内力。进行内力值调幅后计算内力组合，以最不利内力进行梁、柱的配筋计算。按弹性方法对楼梯和基础进行配筋。

Abstract
   The design for the 5-storey frame structure of school building, a total construction area of about 3962.88m2, the main structure of an altitude of about 17.7 m. 7 degrees seismic fortification is located in the region, soil type is a category 2. Structural design is the focus of this design. The design of the main terms: structural design aspects: first axial compression ratio determined in accordance with columns and walls of the section size and beam span estimates beam cross section, calculated the geometric characteristics of the various components of stiffness and structural characteristics of the value system and secondly walls suffered their distribution is the level of load, the calculation of the quality of building self-respect.The calculation of the basic structure of the natural cycle, the calculation of the level of wind loads and seismic shear wall under the internal forces and displacement (of which calculated using shear at the bottom of the earthquake, the building Stiffness along the high quality and relatively uniform distribution, the height of 17.7 m <40m, mainly to shear deformation, applied to the bottom of shear method earthquake). Calculated in the buildings under vertical load of the internal forces. Thinking is calculated structure of the horizontal direction of the lateral rigidity, in the calculation of the level load the internal forces. Internal force is calculated after a combination of internal forces, internal forces in the most unfavorable to beams and columns reinforced calculation. Reinforcement floor calculation: the flexible approach of the roof slab, a reinforced floor and staircases reinforcement.
