摘 要

本毕业设计结构为“常州市淹城初级中学综合楼设计”，根据最新建筑结构设计规范及行业其他相关标准，以安全性、适应性、耐久性为原则对常州市（7度区）淹城初级中学综合楼进行整体结构设计并手算一榀框架。上部结构根据建筑功能及其他因素采用钢筋混凝土框架结构体系，下部结构根据地勘报告采用独立基础。

结构设计通过手算对1/7号轴一榀框架进行受力分析，利用PKPM对结构整体进行建模电算分析。结构设计内容主要包括：结构方案确定、结构荷载确定、结构整体计算、构件内力计算、构件配筋计算及结构施工图绘制等。计算荷载与内力时，手算采用弯矩二次分配法、D值法与底部剪力法，电算采用有限元法和振型分解反应谱法；手算忽略楼梯对主体结构刚度的影响，电算采用楼梯参与整体计算与不参与计算的包络结果。对比一榀框架手算结果与电算结果发现，竖向荷载与水平荷载作用下框架内力计算结果有一定误差。

施工图至少有六张，其中要包括：结构平面布置图；基础平面布置；楼、屋盖梁配筋图；楼、屋盖板配筋图；框架柱配筋图；楼梯的结构布置图和配筋图；施工说明图

关键词：中学综合楼；框架结构；结构设计；独立基础；滑动支座楼梯

Abstract

The graduation design structure is "Changzhou Yancheng junior high school complex building design", according to the latest building structure design specifications and other relevant industry standards, taking safety, adaptability and durability as the principle, the overall structure design of Changzhou Yancheng junior high school complex building (7 degree District) is carried out, and a frame is calculated manually. The upper structure adopts the reinforced concrete frame structure system according to the building function and other factors, and the lower structure adopts the independent foundation according to the geological survey report.

In the structural design, a frame of 1 / 7 axis is analyzed by manual calculation, and the whole structure is modeled and analyzed by PKPM. The structure design content mainly includes: the structure scheme determination, the structure load determination, the structure overall calculation, the component internal force calculation, the component reinforcement calculation and the structure construction drawing drawing and so on. When calculating the load and internal force, the second distribution method of bending moment, the D value method and the bottom shear force method are used in the manual calculation, and the finite element method and the mode decomposition response spectrum method are used in the computer calculation; Manual calculation ignores the influence of stairs on the stiffness of the main structure, and computer calculation adopts the envelope results of stairs participating in the overall calculation and not participating in the calculation. By comparing the results of manual calculation with that of computer calculation, it is found that there are some errors in the calculation results of internal forces of the frame under vertical and horizontal loads.

There are at least six construction drawings, including: structural layout plan; Foundation layout; Floor and roof beam reinforcement drawing; Floor and roof slab reinforcement drawing; Reinforcement drawing of frame column; Structural layout and reinforcement drawing of stairs; Construction instruction drawing .

Key words: middle school complex building; Frame structure; Structural design; Independent foundation; Sliding bearing stair
