Abstract
The present work describes the development of an optimization model for the rehabilitation process of concrete buildings damaged mainly by the effects of an earthquake. Currently, the process is carried out according to the current standards and the damage assessment is based largely on visual damage, which can obviate internal damage to the elements of the structure which cannot be detected at a glance and which will affect its behavior in the future. By means of a non-linear optimization process, the optimization of the modal analysis of concrete buildings has been carried out by means of steel or concrete jacketing in order to reduce the increase in weight generated by these new elements. When analyzing the results it can be observed how increasing the quantity of elements to be repaired increases the complexity to obtain a combination of sections that while keeping the increase in weight to a minimum does not negatively affect its fundamental frequency.
