工字型鋼不論是普通型還是輕型的，由于截面尺寸均相對(duì)較高、較窄，故對(duì)截面兩個(gè)主袖的慣性矩相差較大，因此，一般僅能直接用于在其腹板平面內(nèi)受彎的構(gòu)件或?qū)⑵浣M成格構(gòu)式受力構(gòu)件。

I-steel whether ordinary or light, because the section size are relatively high and narrow, so the moment of inertia of the main secti of the two sleeve is large, therefore, generally only can be directly used in the web plane bending member or the of lattice stress components.

工字鋼的邊長(zhǎng)小，高度大，只能承受單方向的力。  H型鋼槽深，厚度大，可以承受兩個(gè)方向的力。

工字鋼只能用于橫梁，而H型鋼才能用于結(jié)構(gòu)的承重柱。

The length of the I-steel is small and high. It can only bear the force of the single direction. The H steel groove is deep and thick, and can bear the force of two directi.

I-steel can only be used for crossbeams, and H steel can be used for structure bearing columns.

普通工字鋼和輕型工字鋼的型號(hào)是用其腰高厘米數(shù)的阿拉伯?dāng)?shù)字來(lái)表示，腹板、翼緣厚度和翼緣寬度不同其規(guī)格以腰高×腿寬(b)×腰厚(d)的毫數(shù)表示，如“普工160×88×6”。

The ordinary beam and light I-beam model is the digital Arabia with its waist high cm number to represent, web and flange thickness and flange width of different specificati to the waist high (H) * (b) * waist leg width thickness (d). The number of said, such as "general 160 x 88 x 6"
