Then, mechanical property tests of CSLD of different sizes are carried out on press-shear machine, the results show that CSLD has full hysteresis loop and is of the same performance as low yield strength mild steel damper, geometry parameters of different values of CSLD all have influence on its hysteresis loop. Finite element entity modeling and simulation analysis for CSLD are performed using software ANSYS, and contrasted with the above tests results, which indicate they agree well with each other. Then, large numbers of simulation analyses of CSLD of different sizes are carried out, the simulation results and tests results are utilized for the polynomial regression of characteristic parameters of CSLD’s restoring force model. The polynomials express relations between characteristic parameters of CSLD’s restoring force model and geometry parameters of CSLD. Genetic algorithm is used to optimize the geometric parameters of CSLD according to the polynomials, a set of dampers of better energy dissipation capacity are gained. Finally, shaking table tests of a quarter-scale steel building model are carried out, the results of tests indicate that CSLD has full hysteresis loop and help to reduce the structural vibration effectively.
