济南轻型钢结构房屋没有严格的定义，一般可用主要受力构件的截面组成来区分。因此以下的结构都可称为轻型钢结构：

Jinan light steel structure houses do not have a strict definition and can generally be distinguished by the cross-sectional composition of the main load-bearing components. Therefore, the following structures can be referred to as lightweight steel structures:

（1）由冷弯薄壁型钢做成的结构；

(1) A structure made of cold-formed thin-walled steel;

（2）由热轧轻型型钢做成的结构；

(2) A structure made of hot-rolled lightweight steel sections;

（3）由焊接和高频焊接轻型型钢组成的结构；

(3) A structure composed of welded and high-frequency welded lightweight steel sections;

（4）由圆管、方管、矩形管等做成的结构；

(4) A structure made of circular tubes, square tubes, rectangular tubes, etc;

（5）由薄钢板焊成的构件做成的结构；

(5) A structure made of components welded from thin steel plates;

（6）由以上各种构件组合做成的结构。

(6) A structure made by combining various components mentioned above.

判定结构为重钢与轻钢结构确实没有一个统一的标准，很多有经验的设计师或项目经理也常常不能完全说明白，但我们可以以一些数据综合考虑并加以判断：

There is indeed no unified standard for determining whether the structure is heavy steel or light steel, and many experienced designers or project managers often cannot fully explain it. However, we can comprehensively consider and judge based on some data:

一、厂房行车起吊重量：大于等于25吨，可以认为为重钢结构了。

1、 The lifting weight of the factory crane is greater than or equal to 25 tons, which can be considered as a heavy steel structure.

二、每平米用钢量：大于等于50KG/M2，可认为是重钢结构。

2、 The steel consumption per square meter is greater than or equal to 50KG/M2, which can be considered as a heavy steel structure.

三、主要构件钢板厚度：大于等于10MM，轻钢结构用的较少。

3、 The thickness of the main component steel plate is greater than or equal to 10MM, and less is used for light steel structures.

四、另外，还有一些参考值：如每平米造价，大构件重量，大跨度，结构形式，檐高等，以上这些在判断厂房是否为重钢或轻钢时可以提供经验数据，当然现在很多建筑都是轻、重钢都有。但有一些我们可以较肯定的说是重钢：如：石化厂房设施、电厂厂房、大跨度的体育场馆、展览，高层或超高层钢结构。

4、 In addition, there are also some reference values, such as cost per square meter, weight of large components, large span, structural form, eaves height, etc. These can provide empirical data when determining whether the factory building is made of heavy steel or light steel. Of course, many buildings now have both light and heavy steel. But there are some that we can confidently say are heavy steel: such as petrochemical factory facilities, power plant buildings, large-span sports venues, exhibition centers, high-rise or super high-rise steel structures.

五、实际上规范和技术文件都并没有重钢一说，为区别轻型房屋钢结构，也许称一般钢结构为“普钢”更合适。因为普通钢结构的范围很广，可以包含各种钢结构，不管荷载大小，甚包括轻型钢结构的许多内容，轻型房屋钢结构技术规程只是针对其“轻”的特点而规定了一些更具体的内容，而且范围只局限在单层门式刚架。

5、 In fact, there is no mention of heavy steel in national regulations or technical documents. To distinguish light steel structures in buildings, it may be more appropriate to refer to general steel structures as "ordinary steel". Because the scope of ordinary steel structures is very wide, it can include various steel structures, regardless of the size of the load, and even many aspects of lightweight steel structures. The technical specifications for lightweight building steel structures only specify more specific content based on their "light" characteristics, and the scope is limited to single-story portal frames.

六、轻钢也是一个比较含糊的名词，一般可以有两种理解。一种是现行《钢结构设计规范》（GBJ 17－88）中第十一章“圆钢、小角钢的轻型钢结构”，是指用圆钢和小于L45＊4和L56＊36＊4的角钢制作的轻型钢结构，主要在钢材缺乏年代时用于不宜用钢筋混凝土结构制造的小型结构，现已基本上不大采用，所以这次钢结构设计规范修订中已基本上倾向去掉。另一种是《门式刚架轻型房屋钢结构技术规程》所规定的具有轻型屋盖和轻型外墙（也可以有条件地采用砌体外墙）的单层实腹门式刚架结构，这里的轻型主要是指围护是用轻质材料。既然前一种已经快取消，所以现在的轻钢含义主要是指后一种。

6、 Light steel is also a relatively vague term, which can generally be understood in two ways. One type is the "Light Steel Structure with Round Steel and Small Angle Steel" in Chapter 11 of the current "Design Specification for Steel Structures" (GBJ 17-88), which refers to light steel structures made of round steel and angle steel smaller than L45 * 4 and L56 * 36 * 4. It is mainly used for small structures that are not suitable for manufacturing with reinforced concrete structures during the steel shortage era, and is now largely not used. Therefore, in this revision of the steel structure design specification, it has basically tended to be removed. Another type is the single-layer solid web portal frame structure with light roof and light exterior walls (or masonry exterior walls can be used conditionally) specified in the "Technical Specification for Steel Structures of Light Buildings with Portal Frames". The light weight here mainly refers to the use of lightweight materials for enclosure. Since the former type is about to be cancelled, the current meaning of light steel mainly refers to the latter type.

由此可见，轻钢与普钢之分不在结构本身的轻重，而在所承受的围护材料的轻重，而在结构设计概念上还是一致的。更多相关事项就来我们网站http://www.jnghbxg.com咨询！

From this, it can be seen that the difference between light steel and ordinary steel is not in the light or heavy nature of the structure itself, but in the light or heavy nature of the surrounding materials it bears, and in the concept of structural design, it is still consistent.
