Nature disasters again knock improving the quality of prefab steel structure

Further enhance the public cognition to the steel structure, especially the steel structure housing and accept ability, and the government intensify financial preferential policy support, in the market will be crucial to the development of steel structure industry. The building in the future is main in high-level, high-rise, the seismic energy saving, low carbon environmental protection, which is the steel structure building the unique advantages of "high, big and light". Currently, prefabricated steel structure civil industrial technology innovation and strategic alliances are included in the national pilot industrial technology innovation and strategic alliances.

Architect said that Chile is widely used "strong column weak beam" Seismic Design: by breaking the beam to buffer the earthquake energy, but the column is not broken, as far as possible to ensure that the whole building will not collapse, thereby reducing casualties to the greatest extent. Therefore, good shock resistance steel building has been large-scale promotion, mitigation achieved remarkable success.
Steel buildings are excellent in light weight, small inertia force, emergencies seismic performance characteristics after several verification, making daily living more safe and secure. Promote the use of steel structure housing, both green energy and can increase the effective use of space, but also more effective than the traditional steel seismic building.

Our country is a frequent earthquake disaster power, according to statistics, housing structures and materials issues are important factors directly cause casualties.

In response, the Chinese construction metal structure association suggested that earthquakes is a wake-up call, countries should promote steel structure residence in earthquake zones, abandons the traditional low construction practice. Steel structure for steel mechanics performance, has the incomparable flexibility of traditional concrete structures. Under the same seismic force, the steel structure will not break;And reinforced concrete structure is relatively larger rigidity, when the external force than can withstand the limit can partial damage or completely destroyed. Take the steel structure at moderate height as an example, using steel structure building is reinforced concrete structure weight lost about a third, seismic action can be reduced by 30% ~ 30%, on the ground can also reduce the load per unit area of more than 25%. Thus, steel structure building earthquake resistance performance is superior to traditional architecture.
