Influence of Soil Type on the Structural Behavior of Reinforced Concrete Buildings with Elastomeric Anti-seismic Isolators

The study's general objective was to analyze soil type's influence on the structural behavior of reinforced concrete buildings with elastomeric anti-seismic isolators. The study was treated with a quantitative approach, a non-experimental design of applied type, with a comparative scope, considering the object of study as category A1 buildings related to structures erected on soil profiles S1 and S3 and the sample as a dual structural system of category A (clinical) with the incorporation of an isolation interface, structure formed by 4 levels with soil factor type S1 and S3. The techniques used were the structural approach in the plan and height of the building and the use of software for modeling, correction, and scaling of earthquakes. Initially, static and dynamic seismic analysis was performed. As a result, it was obtained that the values of energy input to the structure and the values of dissipation or absorption of such energy by the HDRB isolation devices, allow a ratio between S3/S1 soils, which reaches values of up to 75%. Consequently, it is concluded that on S1 soil, HDRB isolators will make a better contribution and will dissipate a higher percentage of input energy; in addition, they will strengthen the seismic behavior of a type A1 building.
