某五层框架办公楼毕业设计(4402.48平米+建筑+结构+计算书)

拓新办公楼设计

摘要

本工程为xxxx限公司的拟建办公楼，建筑设计为四层，建筑面积一共为4402.48平方米，楼房标高为19.8米。一层主要设计为大厅，接待室和设备用房，二至五层为标准办公用房。建筑采用比较规则的柱网设计，为办公空间的灵活组合划分提供条件，亦对工程造价提供了较为经济的的方案。本工程结构设计采用多层钢筋混凝土框架结构，基本步骤为：结构计算简图的确定；荷载计算；内力分析；内力组合；梁、柱截面配筋、板的设计、基础的设计以及结构施工图的绘制等。其中，内力计算只考虑恒荷载和活荷载；柱、板的设计采用弹性理论；梁的设计采用塑性理论；基础选用柱下独立基础。在进行截面设计时，遵循了强剪弱弯，强柱弱梁，强节点弱构件的设计原则，且满足构造要求，除对本框架进行手算外，还利用了PKPM 对本结构进行了电算。

本设计从建筑到结构是一个较为完整的设计过程，通过毕业设计复习和巩固了以前所学知识，把主要课程联系成一个完整的体系，并运用于设计中；本次毕业设计培养了我进行独立设计的基本能力，为毕业后的工作打下了坚实的基础。

Design of Office Building for TuoXin

ABSTRACT

The engineering is planned for a proposed office building for Tuoxin. which is divided into five stories. The building covers a total construction area of 4402.48 square meters and stands a ground elevation of 19.8 meters. The first storey includes the hall, reception room and spare room, while from the second storey to fifth storey are standard office. The building uses regular pillars net design, resulting in flexible combination and division for office space and a more economical scheme for the project .

The design of engineering structures using multi-storey reinforced concrete frame structure, the basic steps are: the determination of the structure of the calculation diagram; load calculation; internal force analysis; combination of internal forces; beams, reinforced concrete column cross section, board design, basic design and structural mapping, such as construction. Among them, the internal force calculation concerns the constant load and live load only. The column and board design use a flexible plate theory; beam design uses plastic theory; The basis uses column-under single foundation. Seismic design in cross section, follows the design principles of strong bent weak shear, weak beam strong column and strong node weak component, and meet the construction requirements meanwhile. Moreover, the structure computerization is shown by using PKPM.

From construction to the design of structure is a rather complete design process. Through design review and consolidation of the previous knowledge, the main courses are linked into a complete system and used in this design; The Graduation Project has trained me in the basic ability of independent design ,which lays down a solid foundation for the work after graduate.
