• Abstract:

  The objective of this work is to develop an application of structural reinforcement to the building of the Institute of dairy products and fatty derivatives of the PJC in Arganda, which is configured by metal frame frames, applying a solution analyzed with the prestressing method.

  A structural analysis of the building was carried out to know its current behavior. With the data obtained, the case of removing a pillar on the ground floor was raised, leaving a span twice as long, this because it is a critical situation. Under these conditions, a new analysis was carried out to determine the new way of working in the building. This resulted in elements that did not meet the structural safety conditions, which is why a reinforcement design was proposed. For this, the analysis was carried out by means of matrix calculation and once its effectiveness was verified, the elements that make up the reinforcement were designed.

  With the results obtained, it is intended to promote the use of prestressing as a reinforcement solution in cases of metallic structure buildings and to verify that the proposed method is applicable and presents a feasible solution.
