In structural engineering, damping can be defined as a kind of energy which can resist vibration.
Summary (1)After using BRB, We can not only increase the stiffness of the structure, improve the ductility of the structure, but also can bear larger seismic load, and the structure of inter story displacement angle is smaller than the reinforced concrete structure, which has important application value in Anti-seismic engineering field

Experimental Investigation Properties on Resistance of Slag Cement Concrete to Sulfate Attack Jun Wang1, a and Zijian Zhang2,b 1School of Architectural Engineering, Shandong University of Technology, Zibo, Shandong, 255049 China 2 School of Civil and Environmental Engineering, University of Science and Technology Beijing ,Beijing ,100083 China algdwangjun@126.com, bxiaowukong@163.com Keywords: Slag Cement; Concrete; Water-Cement Ratio; Sulfate Erosion Abstract.
The soil, groundwater, marine, industrial waste water contains sulfate ions which penetrate into the concrete and react with cement hydration products, leading to concrete expansion, cracking, spalling and the decrease of the concrete strength, resulting in structure engineering accidents with casualties and economic losses.
Therefore, sulfate resistance of concrete drives the general attention of the civil engineering sector [2].
