For the design of
light steel buildings, each region will according to local geological conditions to define different housing seismic fortification intensity, specifically is an ability of building to prevent the destruction from the earthquake. The seismic fortification intensity of each city and region is different, and the seismic fortification intensity of the general city is in the 6-9 degree. While the general building of the useful life is 50 years, that is, the corresponding period of seismic fortification intensity is 50 years.
The design and construction of
light steel structure house of our country is according to the current national standard "The Low Rise Cold-formed Thin-walled Steel Housing Technical Code For Building" JGJ227-2011, and "The Low Rise Cold-formed Thin-walled Steel Housing Technical Code For Building" JGJ227-2011, approved by the Ministry of housing and urban and rural construction in 2011 on January 2, announcement, released.
The formulation process, the working group including Shanghai Tongji University and Xi'an Architecture And Technology University were investigated extensively , to complete the three full scale vibration table test (a 2 layer, two layer 3) of the rules. The research shows that the key to ensure the overall stability of the
light steel structure is to ensure the structural seismic resistance of the structure when anti-shear and anti-pull connecting between the layers of the
light steel building. According to the experimental phenomenon, such
light steel buildings can meet the requirements of do not collapse in the earthquake intensity of 9 degrees.
