Steel structure of bulk density, although larger, compared with other building materials, its intensity is much higher, so when under load and conditions at the same time, the light steel structure is better than other types of structure.

Mainly displays in:

(1) the constant load is light Use of lightweight enclosure structure, constant load and greatly reduce the earthquake effect, the basic form is simple, low requirement to the foundation, has good seismic performance.

(2) the component section small it adopts new design theory and high strength steel, a new structural system, bearing component cross section is small, low quantity of steel.

As a result, the steel structure engineering with reinforced concrete "deep base fat, fat column, beam, heavy cover" structure, compared to the "light" word more outstanding.Because, without crane beam for industrial and civil building, light steel structure of the steel consumption is generally 20 to 50 kg/m2, as a result, it is more suitable for some relatively soft foundation area.

2. High degree of pre-production

In the field of construction, reduce the production cost, shorten construction time limit for a project is the main goal of the construction enterprise.Due to steel structure modular coordination, unified, standard, realize the construction of large-scale industrialization of pre-production, different materials, different shapes and different manufacturing methods of components has certain commonality and swap.Moreover, due to the connection of steel structure members are connected by bolts, rivets and welding, so it has the characteristics of the construction is convenient.Under the same condition, the steel structure engineering compared with reinforced concrete construction period, the former is the 1/3 of the latter only - 1/4.Therefore, the steel structure project construction period is short of its most competitive characteristics.

3. The good plasticity and toughness of steel

As we all know, for building components, requirements artifacts when the failure should be plastic damage, most avoid is brittle failure, or sudden destruction.The steel due to its high elongation, illustrates its plasticity is good.Such steel structure engineering in general will not suddenly by accidental overload or partial overload damage.And because of its good toughness, can make the steel structure has better adaptability to dynamic loading.Therefore, the plasticity and toughness of steel on steel structure engineering safety reliability for good quality assurance.
