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.

輕型鋼結(jié)構(gòu)大都是冷彎薄壁型鋼，熱軋輕型型鋼，薄鋼板焊成的構(gòu)件做成的結(jié)構(gòu)，都是輕型的鋼結(jié)構(gòu)，還有一種是用斷面較小的型鋼制作桁架，在組成骨架結(jié)構(gòu)，這種也屬于輕型鋼結(jié)構(gòu)。

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.

重型鋼結(jié)構(gòu)就比較好確認(rèn)，廠房行車(chē)起吊重量大于等于25噸，每平米用鋼量大于等到50千克，再就是主要構(gòu)件鋼板的厚度大于等于10毫米，這種都可以確認(rèn)為重型鋼結(jié)構(gòu)，還有就是結(jié)構(gòu)形式等，也可以判斷為重型鋼結(jié)構(gòu)。

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.

從以上介紹可以看得出來(lái)，輕型鋼結(jié)構(gòu)和重型鋼結(jié)構(gòu)，還是很好區(qū)分的，如果是要用輕型鋼結(jié)構(gòu)，歡迎與我公司聯(lián)系，期待與大家的合作。

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.

那么在設(shè)計(jì)輕型鋼結(jié)構(gòu)時(shí)，有什么設(shè)計(jì)原則需提前了解呢？

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

一、按照正常使用狀態(tài)設(shè)計(jì)時(shí)，需要考慮載荷載短期效應(yīng)組合，采用載荷標(biāo)準(zhǔn)值和容許變形進(jìn)行計(jì)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、在建筑結(jié)構(gòu)的兩個(gè)主軸方向，分別考慮水平作用，并且還要進(jìn)行抗震驗(yàn)算，不用考慮垂直作用，水平對(duì)結(jié)構(gòu)的作用，也可采用底部剪力法進(jìn)行計(jì)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、按照承載能力極限狀態(tài)設(shè)計(jì)輕型鋼結(jié)構(gòu)時(shí)，建議大家要考慮荷載效應(yīng)的基本組合，以及荷載效應(yīng)的偶然組合，用荷載設(shè)計(jì)值進(jìn)行計(jì)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.

相信大家在設(shè)計(jì)輕型鋼結(jié)構(gòu)時(shí)，按照使用要求設(shè)計(jì)，更能達(dá)到使用要求，若要安裝輕型鋼結(jié)構(gòu)，歡迎大家與我公司聯(lián)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.
