【摘要】：朝鲜族是中国具有代表性的少数民族之一,主要分布在中国东北三省,本论文的工程位于吉林省延边朝鲜族自治州首府延吉市,项目用途为延边城市展示中心(延边朝鲜族青少年科技创新教育实践基地),项目外型为朝鲜族民族服饰中的帽子造型,结构设计的难点为大跨度楼面及三层大尺寸悬挑。本论文全面地展现了从方案阶段到主体封闭阶段完整的项目设计周期,并重点进行了结构计算和钢结构模型分析,给以后类似项目的结构计算和设计提供了宝贵经验。主要内容包括：(1)绪论：分析了国内类似工程及本工程的主要结构类型及特点,并系统地介绍了本工程结构设计所使用的软件及其特点；(2)建筑设计简介：对延边城市展示中心的建筑方案及建筑初处设计成果进行了简单介绍,并根据该建筑方案,提出了进行结构设计时的三个难点问题,即悬挑问题、结构超限问题和结构转换问题；(3)结构初步设计：确定了建筑分类等级、主要荷载(作用)取值及主要结构材料等,对地基基础、上部结构及地下室进行了初步设计,并提出了此阶段结构设计中的特殊做法及措施；(4)混凝土部分结构计算及施工图设计：利用盈建科软件对整个结构进行了建模分析,并重点对独立基础、挡土墙以及条形基础进行了计算,最后指出了施工图设计阶段,对原方案所做出的修改；(5)钢结构部分模型分析：对工程中的钢结构部分进行了建模分析,包括屋面中央网架应力分析和钢桁架节点有限元分析两部分,结果表明,在最不利荷载组合下,网架体系和钢桁架节点都处于安全状态；(6)结论：本工程出现的结构技术问题及解决汇总。
[Abstract]:Korean nationality is one of the representative ethnic minorities in China, mainly distributed in three provinces of Northeast China. The project of this paper is located in Yanji City, capital of Yanbian Korean Autonomous Prefecture, Jilin Province. The purpose of the project is the Yanbian city exhibition center (Yanbian Korean youth science and technology innovation education practice base), the appearance of the project is the hat shape in the Korean nationality national dress, the difficulty of structure design is long span floor and three stories large size cantilever. This paper presents a complete project design cycle from the project stage to the main body closure stage, and focuses on the structural calculation and steel structure model analysis, which provides valuable experience for the structure calculation and design of similar projects in the future. The main contents are as follows: (1) introduction: analyzing the main structure types and characteristics of similar projects in China and this project, and systematically introducing the software and its characteristics used in the structural design of this project; (2) Architectural design brief: the architectural scheme and the initial design results of Yanbian City Exhibition Center are briefly introduced. According to the architectural scheme, three difficult problems in structural design, that is, the cantilever problem, are put forward. (3) the preliminary design of the structure: the classification grade of the building, the value of the main load (action) and the main structural materials are determined, and the foundation, superstructure and basement are preliminarily designed. The special methods and measures in the structural design of this stage are put forward. (4) the calculation of concrete partial structure and the design of construction drawing: the whole structure is modeled and analyzed with the software of Yingjian Science, and the independent foundation is emphasized. The retaining wall and strip foundation are calculated. At last, the modification of the original scheme is pointed out in the design stage of the construction drawing. (5) partial model analysis of steel structure: modeling and analysis of the steel structure part in the project, It includes two parts: stress analysis of roof central truss and finite element analysis of steel truss joint. The results show that the grid system and steel truss joint are in safe condition under the most unfavorable load combination. (6) conclusion: the structural technical problems and solutions of this project are summarized.
