某一层钢结构厂房 建筑绪论_secret

1、装订线安徽工业大学 毕业设计（论文）报告纸六安先锋钢构公司轻钢结构厂房设计摘要本设计是单层双跨轻钢结构工业厂房，采用门式刚架结构：每跨18米，每跨中都设有一台10吨、A3级桥式吊车。设计主要依据钢结构设计规范（GB500172003）和门式刚架轻型房屋钢结构技术规程（CECS102：2002）等国家规范。确定刚架平面布置后，先进行各种的荷载标准值计算，利用PKPM软件估算选梁、柱截面进行内力分析及组合，忽略地震荷载等因素的影响。在此基础上确定梁、柱的截面，并且利用位移法求出在荷载组合作用下的结构内力（弯矩、剪力、轴力），验算了其平面内外的稳定性。梁柱均采用Q235钢，8.8级和10.9级摩擦型

2、高强螺栓连接，局部焊接采用E43型焊条。在计算内力组合中，只选用了一种最不利的组合，最安全的结果计算。此外还进行了地基基础的计算，由于厂房处的地质条件较好，故采用了安全的柱下独立基础的设计方案。完成了梁、柱和房屋墙面檩条等构件的内力和截面的计算，及绘制了建筑和结构施工图纸。关键词：轻型钢结构、门式刚架、桥式吊车、内力分析、位移法 、独立基础Design to light steel structural building of Lu AnAbstractThe design to the industrial factory building of steel construction ado

3、pts portal frame structure: Each span is 18 m and consists of 10 tons ,bridge type crane of A3 grade.The design is mainly according to the criterion of “CODE ROR DESIGN OF STEEL STRUCTURES” （GB500172003）and “TECHNICAL SPECIFICATION FOR STEEL STRUCTURE OF LIGHT-WEIGHT BUILDINGS WITH GABLE FRAMES”（CEC

4、S102：2002）etc. After decided the plane arrangement of frame,representative value of load is first caculated. The internal force is analyzed and combined in PKPM so as to choose the section of beam and column and neglectes the factor that earthquake is on the influence of loading etc. Based on these

5、analysis, the section of beam and columniation is decided. Then the vibrate cycle is calculated by the peak-displacement method for structural internal force (bending moment,shearing force and axial force ). Next, checking stability of the plane structure. The steel beam and column employs Q235 carb

6、on structural steel. Connection bolts are high strength of friction type with behavioral grade 8.8 and 10.9. Rod for manual welding usually adopts E43. And during calculate the internal force , a kind of most unfavorable association have been only selected,fetch the safest result to calculate. In ad

7、dition, foundation of the ground has been caculated.Because the geological condition of the place of factory building is better, the design plan is adopted on the individual footing under the post. Having finished the roof beam , internal force and the section of members have been caculated . Finally draw the building and structure.Key Words：Light-weight steel structures、portal frame、bridge type c
