摘 要

这次毕业设计的课题为“江苏省赣榆新城高级中学学生宿舍结构设计”，本次结构设计一共包括两个部分，第一个部分为上部结构，采用现浇的钢筋混凝土框架结构，第二个部分为下部结构，采用独立基础。本工程的建筑面积约为7000平方米。建筑平面较为规则，结构主体一共有5层，底层的层高为4.2米，其余层高为3.6米。本建筑为丙类建筑，设计基准期为50年。抗震设防烈度为7度，设计地震基本加速度值为0.1g，设计地震分组为第二组，场地土类别为二类。

“江苏省赣榆新城高级中学学生宿舍结构设计”的设计内容有结构计算和绘制结构施工图。结构计算的顺序为先用PKPM进行电算，再手算并与电算结果比较，最后电脑出图。

电算的内容需要包括：首先用PKPM根据手算得到的构件尺寸和工程情况进行建模；然后运行SATWE来进行计算分析；接着查看SATWE得到的结果，并依此判断结构平面布置能否满足受力的要求，还需查看有无超筋或少筋情况，如有就进行调整；最后，再运行程序来绘制结构施工详图，包括板配筋图，梁柱配筋图等。

结构应当在保证充分安全的情况下，合理考虑更为经济的方案，既要做到“绿色”施工也要做到安全施工。要严格按照相关的专业规范、相关资料的要求和最新的国家发布的相关的设计规范和要求进行合理的设计计算。

关键词：钢筋混凝土结构设计；框架结构；内力计算；配筋。

Structural Design of Atudents' Dormitory in

Ganyu New Town High School of Jiangsu Province

Abstract

The topic of this graduation project is "structural design of students' dormitory of Ganyu new town high school in Jiangsu Province". This structural design consists of two parts. The first part is the upper structure, which adopts cast-in-place reinforced concrete frame structure, and the second part is the lower structure, which adopts independent foundation. The construction area of the project is about 7000 square meters. The plane of the building is relatively regular. There are five floors in the main structure. The floor height of the ground floor is 4.2 meters, and the other floors are 3.6 meters. The building is a class C building with a design reference period of 50 years. The seismic fortification intensity is 7 degrees, the design earthquake basic acceleration value is 0.1g, the design earthquake group is the second group, and the site soil type is the second group.

The design content of "structural design of students' dormitory in Ganyu new town high school in Jiangsu Province" includes structural calculation and drawing of structural construction drawings. The order of structural calculation is to use PKPM to calculate by computer first, then calculate by hand and compare with the result of computer, finally draw the drawing by computer.

The contents of computer calculation need to include: firstly, the PKPM is used to model according to the component size and engineering situation obtained by hand calculation; Then run SATWE to calculate and analyze; Then check the results of SATWE, and judge whether the plane layout of the structure can meet the stress requirements, and check whether there are excessive or less reinforcement, and adjust if there are any; Finally, run the program to draw the structural construction details, including plate reinforcement diagram, beam column reinforcement diagram, etc.

The structure should be in the case of ensuring full safety, reasonable consideration of more economical scheme, not only to achieve "green" construction, but also to achieve safe construction. The reasonable design calculation shall be carried out in strict accordance with the relevant professional specifications, the requirements of relevant data and the latest relevant design specifications and requirements issued by the state.

Key words: reinforced concrete structure design; Frame structure; Internal force calculation; Reinforcement.
