摘 要

在建筑结构设计中，排架结构一直都是大型工业厂房的的主要结构形式而被采用。排架结构具有形成高大的使用空间，容易满足生产工艺流程要求，内部交通运输组织方便，有利于较重生产设备和产品放置，可实现厂房建筑构配件生产工业化以及现场施工机械化等特点。因此，单层厂房在冶金、机械制造、电机制造、化工以及纺织等工业建筑中得到广泛的应用，而本例就是一个典型的排架结构工业厂房设计。

排架结构由屋架或屋面梁、柱和基础组成。通常，排架柱与屋架或屋面梁为铰接，而与其下基础为刚结。所以，排架结构受力机制明确，传力简单。按照厂房的生产工艺和使用要求不同，排架结构可设计为单跨或多跨、等高或不等高等多种形式，在实际设计中非常灵活。

而相较于传统的混凝土排架结构，钢排架自重轻、高度不受限制、并且施工方便，因此受到了越来越广泛的应用。通过钢排架和混凝土排架的对比，我们可以发现钢排架在工业厂房中越来越独特的优势。

Abstract

In the design of architectural buildings,the bent structure has been the most popular structure system for large industrial plant.The bent structure can easily form large space to meet the requirement of production process and the conveniention of internal transportation,and is conducive to the heavier production equipment and product placement.Also, it can complete plant construction accessories industrial production and field construction mechanization. Therefore, the single plant in the metallurgy, machinery manufacturing, motor manufacturing, chemical and textile and other industrial architecture has been widely used,this design is a typical structure of the frame structure of industrial plant design.

Bent structure is composed of roof or roof beam, column and foundation. Usually, bent column and roof or roof beam is hinged, and the foundation for the new. So, the structure of the frame is very clear, the transfer of force is simple..According to the factory production process and the use of different requirements, the structure can be designed single or multi - span, high - range and high – varietyIn the actual,the design is very flexible.

Compared with the traditional concrete frame structure, the steel frame is light, highly unrestricted, and convenient to construct, so it is more and more widely used.Through the comparison of steel frame and concrete frame, we can find that the steel frame is more and more unique in the industrial workshop.

Key Words: the design of structure;the bent structure;the steel structure
