摘要  本次毕业设计为合肥地区加油站钢结构设计，此次设计主要进行的是结构设计部分。本次设计过程主要分为三个阶段：

首先，根据设计任务书对本次设计的要求，通过查阅资料和相关规范确定出结构设计的基本信息，其中包括荷载信息、工程地质条件等。

然后，根据设计信息和功能要求进行结构选型并利用空间结构分析设计软件MST2008进行初步设计。本次设计主体结构形式采用正放四角锥网架结构，节点形式采用焊接球节点，支撑形式采用四根钢柱下弦支撑，基础形式采用柱下混凝土独立基础。

最后，通过查阅相关规范和案例进行檩条、节点、支座等部分的设计，并通过整理分析得出的数据，进行了杆件、结构位移等的相关验算，最终确定了安全、可行、经济的结构模式。

关键词  结构设计，网架结构，构件验算

ABSTRACT and KEYWORDS

Abstract  The graduation project is the design of a steel structure of the gas station in Hefei City. And this design is mainly for structure design. The design process is mainly divided into three stages:

First, According to the requirement of the design specification for the design, through access to information and the relevant specification to determine the basic information of the structural design, including load information, engineering geological conditions, etc.

Second, According to the needs of design information and function structure selection and use of space structure analysis and design software MST2008 for preliminary design. The design of the main structure form using four square pyramid space truss structure, welding ball node form, adopt four pillar of steel bottom chord support, support form using concrete independent foundation under column.

Finally, through cases refer to the relevant specification and purlin, node, bearing and other parts of the design, and through the analysis of data, carried on the bar, the structure displacement, etc. The related calculation, finally determine the structure of a safe, feasible and economic mode.

Keywords  Structural design, bar and node calculation, component checking
