Peru is located in the well-known belt of fire, where the Nazca plate under the South American plate interacts, the same one that develops with an average speed of 7-8 cm / year (DeMets et al, 1980; Norabuena et al, 1999), so we are exposed to important tectonic movements with short repetition periods, earthquakes that have caused many deaths and huge economic losses; Arequipa is located in a seismic zone. Due to this seismic threat, the structural technological innovation proposes the seismic protection of structures through passive devices such as insulators and visco-elastic, friction or metallic energy dissipators. These devices allow the structures to have a better structural behavior, decoupling the structure from the ground with these devices, drastically reducing the seismic movement in the superstructure, which can be imperceptible by users, improving its functionality and operability of the post-earthquake building; however, there is an increase in cost compared to a traditional design. As the superstructure does not have much seismic demand, high-strength steels can be used to reduce concrete sections and minimize steel densities, being able to have steel intersections (knots) with little interference. In the thesis, LRB insulators (lead core rubber) are used for a building of 7 levels with regular plan and elevation, with a slenderness ratio of 2, presenting two dual and porticoed structures. We compare the structural characteristics of the buildings for a conventional design and after proposing the insulation system with 2 types of LRB devices for each structuring, the isolated building proposal is designed with dual structuring with 60-degree construction steel and the building provided with 75-degree steel. A comparison of metrics and budget of structure items is made for the 2 structures with quantities of steel and concrete in columns and beams. It is concluded that it is convenient to structure the porched isolated buildings and use 75 or 80-degree steel without substantially increasing the cost of an isolated building.
