Characteristics of Light Steel Structure Buildings

Characteristics of light steel structure buildings;

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

2.Steel has good plasticity and toughness. The plasticity is good, so that the steel structure will not break suddenly due to accidental overload or local overload. Good toughness makes steel structure more adaptable to dynamic load. These properties of steel provide sufficient guarantee for the safety and reliability of steel structure.

3.Steel is closer to homogeneous and isotropic bodies. The internal structure of steel is relatively uniform, very close to homogeneous and isotropic bodies, and almost completely elastic within a certain stress range. These properties are in good agreement with the assumptions in mechanical calculation, so the calculation results of steel structure are in good agreement with the actual stress conditions.

4.The steel structure is easy to manufacture, easy to adopt industrial production and short in construction and installation period. The steel structure is composed of various profiles and is easy to manufacture. A large number of steel structures are manufactured in specialized metal structure manufacturing plants. High accuracy. The manufactured components are transported to the site for assembly and are connected by bolts, and the structure is light, so the construction is convenient and the construction period is short. In addition, the completed steel structure is also easy to dismantle, reinforce or transform.

Five, steel structure sealing is good. Steel structure has good air tightness and water tightness.

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

Seven, steel is easy to rust, protective measures should be taken. Steel is easy to rust in humid environment, especially in environment with corrosive medium, so it must be painted or galvanized, and it should be maintained regularly during use.
