摘 要

本项目为某高校教学科研楼设计，工程地点位于南京市江北新区。该楼占地尺寸为60m×19m，总建筑面积约6500m²，为六层钢筋混凝土框架结构。建筑首层为4.2m，其余各层均为3.9m，室内外高差0.45m。主要人流通道为两部楼梯和两部电梯。建筑结构安全等级为二级，设计使用年限为50年，抗震设防烈度为7度，设计基本地震加速度值为0.10g，设计地震分组为第一组，工程所在场地类别为Ⅱ类，特征周期为0.35s。地基基础设计等级为丙级，框架的抗震等级为二级。根据工程地质勘察资料，本工程采用桩基础，基础持力层位于第3层密卵石层。

本工程在设计时考虑了建筑物的功能要求，不仅力求建筑美观大方，同时兼顾结构的平面布置。结构设计时，结合南京市当地情况，查找了《荷载规范》、《建筑抗震设计规范》等资料，确定设计所需的荷载及各种计算参数，并主要对结构方案中的第6轴进行了手算。根据所提供的设计资料，完成建筑初步方案设计、建筑施工图设计、框架结构计算、楼梯结构设计、现浇板设计、基础设计计算、构件设计、节点构造设计等，并完成结构施工图绘制、施工组织设计等。手工计算完毕后，用结构分析软件PKPM进行了整体框架计算，并与手算结果进行对比。

Abstract

This project is designed for a university's teaching and research building. The project site is located in Jiangbei New District, Nanjing. The building covers an area of 60m×19m, with a total building area of 6500m². It is a reinforced concrete frame structure with six floors. The first floor of the building is 4.2m, the other layers are 3.9m, and the indoor and outdoor height difference is 0.45m. There are two stairs and two elevators as the main flow channel of the building. The structural safety level is 2 and the designed service life is 50 years. Also, the seismic fortification intensity is 7 degrees and the design basic seismic acceleration value is 0.10g. According to the geological survey report, the design earthquakes are grouped into the first group and the site category is class II. Thus, design characteristic period can be calculated to be 0.35s. In addition, the foundation design level is Grade C and the structural seismic grade of the frame is Grade II. This project uses a pile foundation, the foundation bearing layer is located in the third layer full of pebbles.

When designing, the functional requirements of the building are taken into account. The aim of the design not only strives for the beautiful appearance of the building, but also gives thought to the layout of the structure. At the beginning of the structural design, relative codes such as code for building load, code for seismic design of buildings are searched. Combining with the local conditions in Nanjing, the load and various calculation parameters required for the design are determined. Based on this, the 6th axis in the structural scheme is carried out for manual calculation. According to the design data, preliminary scheme design and construction drawing design of the building are completed. The frame structure calculation, stair structure design, cast-in-place slab design, foundation design, component design and node design are also finished. At last, the project ends with the structural construction drawing and construction organization design. After the manual calculation, the overall framework calculation is carried out with the structural analysis software PKPM, which is compared with the hand calculation results.
