鋼與其他建筑材料相比強度及剛度較大，但仍然是比重非常大的材料。如果鋼與木結構、鋼筋混凝土結構等一樣采用矩形截面構件，其重量會很重，材料造價昂貴，吊裝也變得困難。因此，由于鋼材本身剛度、強度大，常用構件采用滾軋、折疊彎曲制作而成的H型鋼、角鋼等型鋼。下面濟南型鋼廠家來講講鋼結構為什么要采用H型鋼。

Compared with other building materials, steel has greater strength and stiffness, but it is still a material with a very large proportion. If steel and wood structures, reinforced concrete structures and other structures use rectangular section members, their weight will be very heavy, the cost of materials will be expensive, and lifting will become difficult. Therefore, due to the high rigidity and strength of the steel itself, the commonly used members are H section steel, angle steel and other section steel made by rolling and folding bending. Next, Jinan section steel manufacturer will talk about why the steel structure should use H section steel.

鋼結構是高層建筑的一種成本效益高的結構類型，尤其是在地震區。鋼框架-支撐結構在高層鋼結構建筑中應用較多，因為它能更好地協調框架和支撐的受力性能，具有良好的抗震性能和較大的抗側向剛度。鋼框架主要有中心支撐、偏心支撐和消能支撐等。框架。

Steel structure is a kind of high cost - effective structure type of high-rise buildings, especially in seismic regions. Steel frame braced structure is widely used in high-rise steel structure buildings, because it can better coordinate the mechanical performance of the frame and brace, and has good seismic performance and greater lateral stiffness. The steel frame mainly includes central support, eccentric support and energy dissipation support. Frame.

鋼結構電梯井用鋼在什么情況下須使用H型鋼？就是直接用鋼板做剪力墻，并在孔內做加強筋。使用H型鋼也是鋼架結構中柱子倒向電梯井的一種方式。如果高厚比超過標準，就是使用H型鋼，基本上這種大凈高的底層才使用。

Under what circumstances must H section steel be used for steel structure elevator shaft? It is to directly use steel plates as shear walls and make stiffeners in the holes. The use of H-shaped steel is also a way for the column in the steel frame structure to fall to the elevator shaft. If the height thickness ratio exceeds the standard, H-shaped steel is used. Basically, this kind of bottom layer with large net height is used.

鋼框架支撐鋼結構柱用H型鋼和圓鋼有什么區別？;鋼結構柱用H型鋼和圓鋼的區別在于，在橫截面積相同的情況下，抗拉、抗壓能力相同，但抗彎能力，H型鋼在主軸方向上要比圓鋼大得多，所以H型鋼更常用于柱。

What is the difference between H section steel and round steel for steel frame supporting steel structure column?; The difference between H-shaped steel and round steel for steel structure columns is that, with the same cross-sectional area, the tensile and compressive capacities are the same, but the bending capacity is much larger than that of round steel in the main axis direction, so H-shaped steel is more commonly used for columns.

由于承重平臺中點有150噸的集中荷載，鋼框架支撐除滿足結構強度要求外，還必須滿足結構風量要求，同時還要考慮動載（或靜載不規定）的影響。只有提出詳細而具體的荷載條件，設計者才能通過比較結構方案和詳細的結構計算，確認定并選擇合適的方法。

As there is a 150 ton concentrated load at the midpoint of the load-bearing platform, the steel frame support must meet the structural strength requirements, as well as the structural air volume requirements, and also consider the impact of dynamic load (or static load is not specified). Only when detailed and specific load conditions are proposed, can designers confirm and select appropriate methods by comparing structural schemes and detailed structural calculations.
