How to do the seismic effect of steel structure

From low to high seismic level, can be divided into the following several cases.The civil structure of the rural housing is the worst, and the 90% houses collapsed in the Wenchuan earthquake built by this structure;The second is the masonry structure, is generally 6 to 10 layers, the brick body is relatively large and high brittleness;Third is the bottom frame structure. Because the two kinds of materials with different hardness, top-heavy, easy to collapse in the earthquake.

As natural disasters are becoming more and more frequent, a lot of people start to have a doubt: what kind of house has better seismic performance? At present, most of the high-rise buildings with more than 30 storeys are frame shear wall structures,the seismic performance is not good, but the other performance is very good. Shear wall is a reinforced concrete structure, high rigidity, bearing level to strong earthquake intensity.So don't look at the building height, the key to see the building structure.

In the public buildings of more than 10 storeys, it is better to frame structures;the better is the frame shear wall structure, the better is the pure shear wall structure.Steel structure is the most powerful, applied to shopping malls, passenger buildings, also widely used in earthquake countries such as japan. Good elasticity, can absorb the earthquake damage, but the cost is very high.

Frame structures < Shear wall structure < Pure shear wall structure < Steel structure
