摘 要

本设计工程为宜兴地区门式钢结构厂房，主要依据《钢结构设计规范})GB50017-2003和《门式刚架轻型房屋钢结构技术规程》GECS 102:2002等国家规范，综合考虑设计工程的规模、跨度、高度及用途，依据“适用、经济、在可能条件下注意美观”的原则，对各组成部分的选型、选材、连接和经济性作了比较，最终选用单层门式钢架的结构形式。梁、柱节点为刚性连接的门式钢架具有结构简洁、刚度良好、受力合理、使用空间大及施工方便等特点，便于工业化，商品化的制品生产，与轻型维护材料相配套的轻型钢结构框架体系己广泛应用于建筑结构中，本设计就是对轻型钢结构的实际工程进行建筑、结构设计与计算。主要对承重结构进行了内力分析和内力组合，在此基础上确定梁柱截面，对梁柱作了弯剪压计算，验算其平而内外的稳定性;梁柱均采用Q235钢，10. 9级摩擦型高强螺栓连接，局部焊接采用E43型焊条，柱脚刚性连接，梁与柱节点也刚性连接;屋面和墙面维护采用双层彩色聚苯乙烯夹芯板;另外特别注重了支撑设置、拉条设置，避免了一些常见的拉条设计错误。

关键词:轻型钢结构 门式钢架 内力分析 双层彩色聚苯乙烯夹芯板节点

ABSTRACT

This project in YiXing area is a portal frame structure,the project designed strictly complies with the relavant stipulations of the "CODE FOR DESIGN OF STEEL STRUCTURES (GF50017-2003)" and "TECHNICAL SPECIFICATION FOR STEEL STRUCTURE OF LIGHT WEIGHT BUILDINGS WITH GABLED FRAMES (CECS 102:2002)", and some others. Synthesize the scale of the consideration design engineering and across a principle for span and use, according as" applying, economy, under the possible term attention beautifully", Connecting method, structure type and material of each part which consist of a light-weight steel villa are analysed, then choose the construction form that use single layer a type steel. The beam, pillar node is a light steel construction frame system that rigid and copular a type steel a ware for having construction Simple, just degree goodly, suffering dint reasonablely, using space bigly and starting construction convenience etc. characteristics, and easy to industrialisation, commercializing produce, thinking with light maintenance material the kit the already extensive applying in the building construction inside, this design is to proceeds the building, construction design to the structural and actual engineering in light steel and calculation. The tractate includes the internal force analyzes and combines, based on these analyses; we can choose the section of beam and calumniation. Next, checking computatians of stability calculatian of the plane structure. The steel beam and column employs Q235 carbon structural steel. Connection bolts are high strength bolt of friction type with behavioral grade 10.9. Common bolts are rough type made by Q235-B.F steel. Rod for manual welding usually adopts E43..Rigid connections apply to the column leg and the connection of column and beam adopts hinged connection. The metope and roofage adopts the Bauble-decked colored polystyrene clamps the circuit board. otherwise, it is analysed that the forced state of the bracing system for a steel factor building under wind land, and the design of a bracing truss for a building with larger width. Avoid some errors in the design of brace, tension rod, and tension rod jpints.

Keywords:Lightweight steel structures; gabled frame; the internal force analyzes; The double-decked colored polystyrene clamps the circuit board;joint
