摘 要

本次设计主要是办公楼结构设计，铜峰电子公司办公楼是六层办公楼，主体为现浇钢筋混凝土框架结构，建筑面积5400㎡，建筑物共6层，底层层高3.3m，标准层层高3.30m，顶层层高3.30m，室内外高差0.450m。根据要求，设防烈度为7度。该设计一共由两个部分组成，分别是建筑设计和结构设计。

建筑设计是根据已有的面积、层高以及一些必需的有特定功能的空间条件结合房屋建筑设计规范进行合理的设计，例如，柱网的合理分布等。此部分运用的软件有天正建筑和Autocad2010 。建筑设计部分包括建筑设计总说明、建筑总平面布置图、底层和标准层平面图、正立面图、侧立面图、剖面图、建筑节点构造详图的绘制。

结构设计分为手算部分和电算部分，主要包括水平及竖向荷载统计、内力计算、构件配筋及施工图绘制等工作。电算主要运用的软件为PKPM2010，再结合《建筑抗震设计规范》、《建筑结构荷载规范》和《建筑地基基础设计规范》进行设计。手算部分在结构平面布置图的基础上一榀框架的计算，结合《建筑结构荷载规范》进行荷载计算、采用分配法和D值法，完成内力计算和位移验算、根据最不利原则进行内力组合、参考《建筑抗震设计规范》完成截面设计与配筋计算。

关键词：结构布置截面确定；荷载计算；内力计算；配筋设计

Abstract

The design of this project is mainly the structural design of office buildings. The office building of Tongfeng Electronics Company is a six-story office building with a cast-in-situ reinforced concrete frame structure, a building area of ​​5400m2, a total of 6 buildings, and a floor height of 3.3m. The height of the floor is 3.30m, the height of the top floor is 3.30m, and the height difference between indoor and outdoor is 0.450m. According to requirements, the fortification intensity is 7 degrees. The design consists of two parts, namely architectural design and structural design.

The architectural design is based on the existing area, floor height and some necessary spatial conditions with specific functions combined with the building design specifications for rational design, for example, the reasonable distribution of column nets. The software used in this part is Tianzheng Construction and Autocad2010. The architectural design part includes the general description of the architectural design, the general layout of the building, the floor plan of the ground floor and the standard floor, the drawing of the front facade, the side elevation, the section drawing, and the detailed construction of the construction node.

The structural design is divided into hand calculation part and computer calculation part, which mainly include horizontal and vertical load statistics, internal force calculation, component reinforcement and construction drawing. The software mainly used in the calculation is PKPM2010, which is combined with the "Code for Seismic Design of Buildings", "Load Code for Building Structure" and "Design Code for Foundation of Building Foundation". The hand calculation part calculates the frame based on the structural floor plan, combines the “Load Code for Building Structures” to calculate the load, adopts the distribution method and D value method, completes internal force calculation and displacement checking, and performs internal force combination according to the most unfavorable principle. Refer to "Code for Seismic Design of Buildings" to complete section design and reinforcement calculation.

Keywords: structural arrangement section determination; load calculation; internal force calculation; reinforcement design
