四层南京某科技园办公楼设计(含建筑图结构图)(开题报告,论文计算书19000字,CAD建筑图10张,CAD结构图9张)
摘要：本次毕业设计题目为南京某科技园C区2号办公楼设计。建筑面积约为540mm2，采用框架承重结构，主体结构层数为四层，底层层高为4.0m，其它层均为3.6m。抗震设防烈度为7度。设计分为建筑设计和结构设计两部分。
一、建筑设计阶段：根据建筑的使用功能要求，建筑的高度和层数，所属地区的设防烈度以及抗震等级来确定建筑的结构形式；绘制建筑平面图、剖面图、立面图、细部详图和总平面图。
二、结构计算阶段：以③轴线横向框架为计算分析对象。在确定框架布局之后，先计算了恒载，活载作用下的梁端内力，然后用分层法进行内力分配，然后各层叠加，进而求出在竖向荷载作用下的结构内力（弯矩、剪力、轴力）；而水平地震作用和风荷载作用下的框架内力则通过D值法求出。接着内力组合找出最不利的一组或几组内力组合。选取最安全的结果计算配筋并绘图；并进行地基设计。此外还进行了结构方案中的楼梯的设计。完成了踏步板，梯段斜梁，平台板，平台梁等构件的内力和配筋计算及施工图绘制。
此设计选用常用的框架结构形式，通过计算较简单的对称一榀框架，使我对所学的专业知识能够有机的结合起来，对结构设计有了基本的了解，我也相信这次毕业设计的过程能够对以后的学习打下一定的基础。

Abstract:The title of the graduation design is the design for a science and technology park area C of No.2 office building in Nanjing .Total construction area is about 540 sq.m, frame structure,4 floors.The height of the first floor is 4.0m and other layer is 3.6 m,the seismic fortification intensity is 7 degrees.
First,architectural design stage: According to the requirements of the building use function, building height and layers, and the district of fortification intensity and earthquake resistant level to determine the structure of building; Draw the floor plan, section and elevation, detail view details and the total floor plan;
Second, structure computation stage: The computational analysis object is ③ axis horizontal framework.After in determining the frame layout, first to calculate the dead load and live load under the action of the beam end of internal forces, and internal force distribution with the layered method, then each layer overlay, and then calculate the structural internal force under the vertical load (bending moment, shear force, axial force).And level of the framework of internal forces under earthquake and wind load through the D-value method.Then identify the most unfavorable combination of internal forces of a group or several groups combined forces.Select the safest results reinforcement and drawing; And for the foundation design.In addition, the program for the structural design of the staircases. Completed treads, bench inclined beams, platforms plate, platform beams and other components of internal forces and reinforcement calculation and construction drawings.
This design selects the commonly used portal frame construction form, by calculating a symmetrical specimens of relatively simple framework that I have learned expertise to organically combine the structural design of a basic understanding, I also believe that this
graduation design can lay a foundation for future learning process.
keywords: office buildings of architectural frame structure structural design combine inside the dint.
