Numerical Analysis and Comparison for A Low-rise Masonry House with The Application of Seismic Isolator with and without S Shape Steel Dampers

In the recent years, some new hybrid isolation systems researched, for instance, the hybrid device consisting of unbonded seismic isolator and shape memory alloy, hybrid fraction yielding elastomeric bearing and rubber bearing with slit damper devices. In this paper, a novel hybrid seismic system which consists of seismic isolator connected with S-shaped steel dampers (SSSDs) is investigated, and a simplified model of that system is proposed. The numerical model of a small masonry house with the simplified model of a novel hybrid system is established in ABAQUS. The simulations and the comparisons of a low-rise masonry house with and without a novel hybrid system are simulated under the earthquake action based on finite element method. The novel hybrid seismic system applied in a low-rise masonry house has more effective protection by adding SSSDs than traditional isolation system. It can be adopted as a reference to improve mechanical capacity of common isolation system and supple the practical application in the practical engineering.
