The Advantages Of Steel Structure
Light weight, high strength. Although the bulk density of steel structure is larger, its strength is much higher than that of other building materials alone. Therefore, when the loads and conditions are the same, the steel structure is lighter than other structures and takes up relatively little space for transportation and Install, and span a larger span.
Good ductility and toughness of steel. Good plasticity, the steel structure is generally not because of accidental overload or partial overload and sudden rupture damage. Toughness, then the steel structure of dynamic load adaptability. These properties of steel provide a guarantee for the safety and reliability of the steel structure.
The steel structure is easy to manufacture, easy to adopt industrial production, construction and installation of short cycle, construction speed, steel structure from a variety of profiles, easy to make. A large number of steel structures are manufactured in specialized metal construction plants; high accuracy. Made of components transported to the site assembly, the use of bolts, and light structure, it is convenient for construction, construction period is short. Mechanized operation, the duration of construction than the traditional residential system to reduce at least one-third, thus reducing the overall cost, the overall cost reduction of 5%. Speed up the flow of funds, greatly improving investment returns. In addition, the completed steel structure is also easy to dismantle, reinforce or remodel, and the steel structure will not generate construction waste, which is relatively more environmentally friendly.
Compared with other structures, steel structure has advantages in terms of function, design, construction and comprehensive economy. The advantages of steel structure in residential buildings are mainly reflected in the following aspects:
First, the steel structure of residential buildings can better meet the requirements of flexible separation of large open space than traditional buildings, and can reduce the pillar cross-sectional area and the use of lightweight wall panels to improve the area utilization, high-rise building steel structure can save the structure of possession Area of 28%. Thus increasing the area of about 4%. Effective indoor use area increased by about 6%.
Second, the energy-saving effect, the wall with light energy-saving standard prefabricated wall panels instead of clay brick, thermal insulation performance, energy saving 50% per household per square meter can save heating cost of 18 yuan.
Third, the steel structure system for residential buildings can give full play to the ductility of the steel structure is good, plastic deformation ability, with excellent seismic wind resistance performance, greatly improving the safety and reliability of residential. In particular, in the event of an earthquake or a typhoon disaster, the collapse of the building can be avoided. For example, in the 95-year-old Hanshin earthquake in Japan, almost all of the steel structures that had not collapsed in the 1999 Taiwan earthquake were made of H-shaped steel.
In general, steel has the advantages of large span, high strength, light weight, low cost, environmental protection and energy saving, beautiful appearance, short construction period, long service life, high space utilization, good seismic performance and flexible layout. Structure suitable for large factories, warehouses, workshops, and stadiums and other buildings.
