轻型钢结构，它主要是用于不承受大载荷的承重建筑中，如果要承受大的载荷的话，那么就不适用了，是以轻型H型钢，以及C型、Z型冷弯薄壁型钢为基础，再加上压型钢板或轻质夹芯板，以及一些连接件和密封材料而成的。

　　Lightweight steel structure is mainly used in load-bearing buildings that do not bear large loads. If it needs to bear large loads, it is not suitable. It is based on lightweight H-shaped steel, C-shaped and Z-shaped cold-formed thin-walled steel, plus pressed steel plates or lightweight sandwich panels, as well as some connectors and sealing materials.

　　1.种类

　　1. Types

　　轻型钢结构一般有两种，为：

　　There are generally two types of lightweight steel structures:

　　一种是用薄钢板冷轧而成的薄壁型钢，来组成骨架结构；另一种则是用断面较小的型钢，比如角钢、扁钢等，来制作桁架，然后再组成骨架结构。

　　One type is thin-walled steel made by cold rolling thin steel plates to form the skeleton structure; Another method is to use smaller cross-sectional steel, such as angle steel, flat steel, etc., to make trusses and then form a skeleton structure.

　　此外，有时，这两种还可以进行混合使用。

　　In addition, sometimes these two can also be mixed for use.

　　2.优点

　　2. Advantages

　　(1)能够形成坚固的体系，因此具有很好的抗震及抵抗水平载荷的能力。

　　(1) It can form a sturdy system, thus possessing excellent seismic resistance and resistance to horizontal loads.

　　(2)其重量轻、强度高、整体刚性好，而且其变形能力强。

　　(2) It is lightweight, strong, has good overall rigidity, and has strong deformation ability.

　　(3)其结构寿命长，一般可以使用100年之久。

　　(3) Its structure has a long lifespan and can generally be used for up to 100 years.

　　(4)具有很好的保温隔热性能，还有很好的隔音性。

　　(4) It has excellent thermal insulation performance and good sound insulation.
