不承受大载荷的建筑，大都是用的轻型钢结构，用轻型钢做成门形钢架支承，很多人不知道轻型钢结构和重型钢结构的区别，抓紧时间了解下吧。

Buildings that do not bear heavy loads are mostly light steel structures, supported by portal steel frames made of light steel. Many people do not know the difference between light steel structures and heavy steel structures. Take time to understand.

轻型钢结构大都是冷弯薄壁型钢，热轧轻型型钢，薄钢板焊成的构件做成的结构，都是轻型的钢结构，还有一种是用断面较小的型钢制作桁架，在组成骨架结构，这种也属于轻型钢结构。

Most of the light steel structures are made of cold-formed thin-walled steel, hot-rolled light steel and welded members of thin steel sheets. They are all light steel structures. Another is to make trusses from small section steel, which is also a light steel structure.

重型钢结构就比较好确认，厂房行车起吊重量大于等于25吨，每平米用钢量大于等到50千克，再就是主要构件钢板的厚度大于等于10毫米，这种都可以确认为重型钢结构，还有就是结构形式等，也可以判断为重型钢结构。

Heavy-duty steel structure is better confirmed, the lifting weight of workshop crane is greater than or equal to 25 tons, the amount of steel used per square meter is greater than or equal to 50 kilograms, and then the thickness of steel plate of main component is greater than or equal to 10 millimeters, which can be recognized as heavy steel structure, as well as structural form, and can also be judged as heavy steel structure.

从以上介绍可以看得出来，轻型钢结构和重型钢结构，还是很好区分的，如果是要用轻型钢结构，欢迎与我公司联系，期待与大家的合作。

From the above introduction, we can see that light steel structure and heavy steel structure are well distinguished. If you want to use light steel structure, you are welcome to contact us and look forward to your cooperation.

那么在设计轻型钢结构时，有什么设计原则需提前了解呢？

So when designing light steel structures, what design principles need to be understood in advance?

一、按照正常使用状态设计时，需要考虑载荷载短期效应组合，采用载荷标准值和容许变形进行计算。

1. When designing according to the normal working condition, it is necessary to consider the combination of short-term effects of load and adopt the standard value of load and allowable deformation to calculate.

二、在建筑结构的两个主轴方向，分别考虑水平作用，并且还要进行抗震验算，不用考虑垂直作用，水平对结构的作用，也可采用底部剪力法进行计算。

2. In the direction of two main axes of the building structure, the horizontal action is considered separately, and the seismic checking calculation is also carried out. Without considering the vertical action, the horizontal action on the structure can also be calculated by the bottom shear method.

三、按照承载能力极限状态设计轻型钢结构时，建议大家要考虑荷载效应的基本组合，以及荷载效应的偶然组合，用荷载设计值进行计算。

3. When designing light steel structures according to the ultimate state of bearing capacity, it is suggested that the basic combination of load effect and accidental combination of load effect should be taken into account and calculated with the design value of load.

相信大家在设计轻型钢结构时，按照使用要求设计，更能达到使用要求，若要安装轻型钢结构，欢迎大家与我公司联系。

I believe that when you design light steel structure, according to the use requirements, you can better meet the use requirements. If you want to install light steel structure, you are welcome to contact my company.
