Nowadays the main cause of damage of reinforced concrete frames in the countries which are located on the seismic line area is earthquake even though they are designed due to the enactment of seismic codes. To provide a solution to these problems, Lead Rubber Bearing (LRB) system has been utilized in the construction of the buildings. Hence, the objective of this study is to determine the best configuration of the LRB in the structure by calculating the response of the structure, roof level<span class="external-identifiers"> <a target="_blank" rel="external noopener noreferrer" href="https://doi.org/10.11113/jt.v65.2195">doi:10.11113/jt.v65.2195</a> <a target="_blank" rel="external noopener" href="https://fatcat.wiki/release/6n2vdfcff5ferhzu4d464plenu">fatcat:6n2vdfcff5ferhzu4d464plenu</a> </span>

The study consists of determining the structure, calculating the weight of structure, modelling the LRB in the structure and obtaining the output from the dynamic analyses. The comparison of the inter-story displacement, drifts frames and top level acceleration response of the LRB system with the Fixed Base System (FBS) using spectrum and time history analysis shows that the base shear reduces by 65-75% in response spectrum analysis, while in time history analysis base shear reduces by 75-85%. The proposed method is based on the LRB system that reduces the response of the structure because of high damping and stiffness used in the Base Isolation System (BIS) and capable to be used for super structure located in the seismic line area. This system would help in reducing the cost in the long time and increase the safety of the structure.
