With the improvement of science and technology and people's living standard, the ability of prevent earthquake disasters has been improved, the structure of the damping control technology has get more and more researchers’ attention both at home and abroad due to its characteristic of economy applicable energy consumption, simple structure, convenient maintenance, and the better damping effect. so the technology has become an effective method to dissipate earthquake energy.
Mild Steel Damper Material Selection The mild steel damper is made from steel Q235, material constitutive relation uses ideal elastic-plastic material model , the relevant parameters in Table 1.In the Table 1, is yield stress, is ultimate strength, E is modulus of elasticity, is yield strain and is ultimate strain.
Flange plate thickness and length of the specimen are same to H -type dampers ; constitutive relation of other materials using an ideal elastic-plastic model , the parameters in Table 1.
