Advantages and disadvantages of steel structure

Advantages and disadvantages of steel structure

1、 steel structure is light in weight


Although the bulk density of steel structure is large, its strength is much higher than other building materials.Therefore, when the load and conditions are the same, Fuzhou steel structure is lighter than other local steel structures, convenient for transportation and installation, and can span a larger span.


2、 Good plasticity and toughness of steel


With good plasticity, the steel structure will not be broken suddenly due to accidental overload or partial overload.If the toughness is good, the adaptability of steel structure to dynamic load is strong.


3、 steel is closer to homogeneous and isotropic Fuzhou steel structure


The internal structure of steel is relatively uniform, very close to uniformity and isotropy, and almost completely elastic in a certain stress range.These properties are consistent with the assumptions in mechanical calculation, so the calculation results of steel structure are consistent with the actual stress conditions.


4、 steel structure is easy to manufacture, easy to use industrial production, and short construction and installation period


steel structure is composed of various sections, which is easy to manufacture.A large number of steel structures are manufactured in specialized metal structure manufacturing plants with high accuracy.The finished parts are assembled on site with bolt connection, light structure, convenient construction and short construction period.In addition, the built steel structure is easy to dismantle, strengthen or transform.


5、 Good sealing property of steel structure


6、 steel structure has good heat resistance but poor fire resistance


Steel is resistant to heat but not to high temperature.As the temperature increases, the strength decreases.When there is radiant heat around and the temperature is above 150 ℃, the shielding measures should be taken.If a fire occurs and the temperature of the structure reaches more than 500 degrees, the whole structure may collapse instantaneously.In order to improve the fire resistance of steel structure, it is usually wrapped with concrete or brick.


7、 Steel is easy to rust, so protective measures shall be taken


       In humid environment, steel is easy to rust, especially in corrosive medium environment, it must be painted or galvanized, and it should be maintained regularly during use.
