Antonio Murcia totanero is rewarded for his academic work "Structural intervention of the building of the former Post Office of Murcia" (13/12/2019)

The awards recognize those doctoral theses, final degree projects, and final master's degrees that for their quality and originality deserve the recognition of their peers

The Official Association of Surveyors, Technical Architects and Building Engineers of the Region of Murcia (COAATIEMU) rewards different works carried out in the last year by its members.

Among the recognized works are doctoral thesis and final degree and final master's degree projects.

The jury has been formed by members of the College, the UCAM, and the UPCT.

The awards ceremony will take place tomorrow, December 14 at the annual brotherhood dinner that will take place at the Nelva Hotel.

For the president of the College, Antonio Mármol, the call for these awards for doctoral theses, and final master and degree assignments implies a fair recognition to the professional professionals who have contributed with their effort to the positioning of the profession in the academic field.

The totanero Antonio Murcia, awarded for his academic work "Structural intervention of the building of the former Post Office of Murcia"

The objectives of the Final Degree Project prepared by Antonio Murcia have been, on the one hand, to analyze, dimension, describe and detail the reinforcement elements and productive processes necessary to provide the structure of the building with the resistant capacity appropriate to the new use that It is intended to give, in addition to justifying that the reinforced structure has sufficient capacity to withstand the efforts to which it will be subjected during the useful life of the building, as well as to monitor the work and be able to compare the designed with the really executed.

The methodology followed can be divided into two parts, a first phase of study and sizing of the necessary reinforcements, for which the analysis of each structural element and its resistant capacity is detailed, comparing it with the requests it receives, and the elaboration of the methods of calculation for the sizing of the different reinforcements that arise, developing the necessary procedures and spreadsheets, according to Totana.com Antonio Murcia.

In a second phase, since the work has been executed during the elaboration of the final degree project, a comparative analysis between the designed and the really executed is carried out, developing monitoring sheets of each work unit.

A Quality Control Program is also elaborated for this type of actions in which the necessary tests and tests for the materials and work units proposed are analyzed, analyzing the results obtained.

Finally, an economic study of the different work units necessary for the execution of the work is prepared, comparing the economic cost planned in the project and the one finally executed, analyzing the differences that have existed and making an assessment of them.

Once all the work has been done, the following has been revealed:

The structure of the building of the old post office presents a series of damages of considerable importance in many of its structural elements.

At the foundation level there are important seats, both in the perimeter walls, and in the interior pillars.

In the reinforced concrete aerial structure, various damages have been identified due to its aging, lack of maintenance and poor conservation.

It has also been proven that many of the elements of the existing structure, do not have sufficient capacity to withstand the efforts, caused by the new overloads due to the new use that is intended to be given, with the safety coefficients established in the current regulations.

The structural reinforcement elements necessary to provide the structure with sufficient capacity to withstand the expected overloads have been studied, proving to be very variable and although they are all part of the structure as a whole, they have very significant differences in terms of their conception in the design and dimensioning and its structural function.

As for the reinforcement of the foundation elements, a reinforcement has been designed through a new structure inside the building, attached to the existing perimeter loading walls, which receives the loads from the slabs and unloads the walls.

This structure has been solved by concrete beams that wraps the slabs and transmits the loads to the ground by concrete or steel pillars and finally to micropiles executed in the semi-basement of the building.

The reinforcement of the foundation of the interior pillars of the building has been resolved by a micropile overhang, connected to the existing mass concrete footings.

A spreadsheet for micropile sizing has been developed, in which, by introducing the characteristics of its component materials and the geomechanical parameters of the terrain, the resistant capacity of the same is obtained, depending on the depth of embedment.

In order to provide the structure with adequate resistant capacity, a reinforcement of the slabs and beams has been designed and sized, by means of the execution of a compression layer, where corrugated steel bars have been anchored to give greater capacity to flexural strength negative to the beams and the anchoring of metal plates in the lower area of ​​the beams, to give greater resistance to bending to positives.

This reinforcement has had to be calculated and dimensioned by means of a tension analysis of the section manually, without the possibility of help of computer programs, since it is a section composed of concretes of different characteristics and metal plate anchored to hardened concrete.

The economic analysis of the work has shown that, although small changes have been made in the construction phase of the construction process, the final cost of the work has not been practically altered in relation to to the work units planned in the project.

However, during the execution of the work, a series of damages in the structure and various complementary work units have been detected that, due to the conditions in which the building was when the study was carried out, could not be foreseen, these Complementary actions have meant an increase of 3.8% of the anticipated initial cost, which for these types of actions is well below normal.

As a final conclusion, Antonio considers that it may be interesting to make a general study of this type of structural reinforcements and those that may arise in other structures, developing a practical manual specifying a method for the design, calculation and dimensioning of each kind of reinforcement.
