其中，轻钢厂房不仅重量轻、耗钢量低、施工速度快，而且抗震能力强，可以提高整个建筑的综合抗震性能。它是目前工业厂房中广泛使用的一种结构形式。

轻钢结构由基础梁、立柱、檩条、楼板和墙体组成。单层轻钢厂房一般采用门式刚架。门式刚架为大跨度钢结构厂房大坡度排水创造了条件。设置中间柱可以减小梁的跨度，降低造价。中间柱由钢管和铰接式摆动柱组成，占用空间小。门式刚架的横向刚度由檩条支撑保证，省去了纵向刚构件，减小了翼缘宽度。钢框架可采用与弯矩成正比的变截面，变截面时可根据需要改变腹板的高度、厚度和翼缘的宽度，以充分利用材料。

轻钢厂房钢框架腹板可按有效宽度设计，即允许部分腹板失稳，并可采用其后屈曲强度。竖向荷载通常是设计控制荷载，但当风荷载较大或房屋较高时，风荷载的作用不容忽视。在轻型屋盖门式刚架中，地震作用一般不起控制作用。支架可以变得更轻。可直接与腹板连接，也可与水平节点板连接，可采用受拉圆钢。所有结构件均可在工厂内制造，产业化程度高。各组成单元可根据运输条件进行划分。这些单元在现场用螺栓连接。安装方便快捷，土建工程量小。

轻钢厂房的组成与梁、柱、屋架、屋顶、基础等部分的因素密不可分。轻钢结构厂房的组成与普通钢结构厂房基本相同。因为许多建筑结构类型比较相似，但在材料或其他结构构件上有很大的差异。轻钢结构厂房是许多工业厂房中常见的建筑物，因此相关技术已趋于成熟。相信今后轻钢结构的应用会越来越广泛。

The workshop can be constructed in many forms and ways. Nowadays, the most common one is the steel structure workshop, which mainly takes the steel structure as the main load-bearing structure, the wall can be brick concrete structure or steel structure, most of which are made of color plates, and then the workshop composed of doors, windows and other components. Due to the increase of steel output in China, many light steel workshops are used, and steel structures are mostly prefabricated in factories, which can reduce the construction amount and cost.

Among them, the light steel plant is not only light in weight, low in steel consumption and fast in construction, but also has strong seismic capacity and can improve the comprehensive seismic performance of the whole building. It is a structure widely used in industrial plant at present.

Light steel structure is composed of foundation beams, columns, purlins, floors and walls. Single story light steel plants generally adopt portal steel frame. Portal steel frame creates conditions for long slope drainage in large span steel structure plants. Setting intermediate columns can reduce the span of beams and reduce the cost. The middle column is made of steel tube and hinged swing column, which takes up little space. The lateral rigidity of the portal steel frame is guaranteed by purlin support, the longitudinal rigid members are omitted, and the flange width is reduced. The steel frame can adopt variable section, which is proportional to the bending moment; when changing the section, the height and thickness of web and the width of flange can be changed according to the needs, so as to make the best use of the materials.

The webs of the steel frame of the light steel workshop can be designed according to the effective width, that is to say, some webs are allowed to lose stability and their post buckling strength can be used. Vertical load is usually the design control load, but when the wind load is large or the house is high, the role of wind load should not be ignored. In the light roof portal frame, the seismic action generally does not play a controlling role. Support can be made lighter. It can be connected to web directly or with horizontal gusset plate, and the tensioned round steel can be used. All structural components can be manufactured in the factory with high industrialization degree. The component units can be divided according to the transportation conditions. The units are connected by bolts on the site. The installation is convenient and fast, and the amount of civil construction is small.

The composition of the light steel workshop is inseparable from the factors of beams, columns, roof trusses, roofs, foundations and other parts. The composition of the light steel structure workshop is mostly the same as that of the ordinary steel structure workshop. Because many building structure types are relatively similar, but there are great differences in the materials or other structural components. Light steel structure workshop is a common building in many industrial workshops, so the relevant technology has become mature. I believe that the use of light steel structure will be more and more extensive in the future.
