摘 要
本文的毕业设计主要讲述了综合楼设计。设计的内容主要为结构设计。毕业设计是土木工程专业的必修课程，我的设计是综合楼设计，设计采用钢筋混凝土现浇框架结构，建筑层数为七层，建筑总高度31.0m，总建筑面积5445㎡，底层占地面积为806.88㎡。根据设计要求，设防烈度为7度，抗震等级为三级，设计中要考虑抗震设计。设计包括结构部分、楼梯、基础等。根据任务书定出各层平面图及平面布置。本方案主体结构为双向承重框架，横向框架等跨。在进行荷载计算和构件截面估算后，选取了一榀框架进行计算，计算内容包括框架梁柱截面尺寸的选取及线刚度的计算；地震作用下梁端、柱端弯矩、剪力的计算；框架梁柱配筋计算；楼梯配筋计算及基础配筋计算。框架受力钢筋主要采用Ⅱ级钢筋，箍筋主要采用Ⅰ级钢筋，楼梯采用钢筋混凝土板式楼梯；由于柱网的限制，基础采用钢筋混凝土柱下独立基础。整个方案设计基本符合设计和结构要求，具有一定的合理性。
通过对综合楼楼层平面图、剖面图、构造图的绘制和结构的设计，熟悉了设计的全过程，掌握了结构设计计算的基本方法，创造性地完成了毕业设计任务。同时，对这些年所学的专业知识和基本概念有了更深的理解，从而提高了分析和解决实际问题的能力。

Abstract
The paper mainly presents the design of synthetical building． This design includes construction design ．Design project for graduation is civil engineering special field of study required course , It is that the synthetical building designs to originally design . This scheme adopts the cast-in-place frame structure of armored concrete . Structure rand order is three layer .Structure total height31.0 meter and surfarce area 5445 suquare meter, the floor space of ground floor is 806.88㎡. According to the designing requirement , the earthquake intensity is 7 degrees to set up defences, the grade of antidetonation is two grade, consider aseismatic design in the design. Design project include constructure part、staire and foundation ,according to assignment book define every layer blueprline and plare arrange. The agent structure is a two-way bearing frame , horizontal frame ,etc.are stepped. In is it is it calculate and component section after estimating , choose one Pin frame calculate to load to go on, consideration substarece include select frame column section measurement and thread rigidity ;calculate seismic action produce roof beam extremity and column extremity bending moment 、shear and axle power;Frame interral force make up; Mate steel;Stairs mate steel and foundation mate steel calcucate.This office building adoupt L model arragnge .Frame be subject to power steel adoptⅡleveland hoop steel adoptⅠlevel.Staire adopt steel concrete type of meter for chinese and foundation adopt linear leaf. The whole conceptual design accords with the design and structure demand basically, have certain creativity and rationality.
Through the design of synthetical building floor construction, and drawing floor plan ，constructed profile and constructional drawing, I am familiar with the principle design of construction, and controlled the basic methods of computation of the construction design,and my work is creative. at the same time, I have a deeper understanding of the first several years’ profession learning and the foundation knowledge. as a result, My ability that analyzing and solving the actual problems is increased.
