En estos días he estado revisando la biblioteca de RDT en Anantapur. Tienen un buen número de documentos de interés. Tal vez el que mejor pueda servir a los cooperantes del Departamento de Arquitectura sea RDT Engineering Training Course - August 2004, un manual de apuntes de construcción y hormigonería a modo de resumen de un curso impartido en el Campus I en 2004, promovido por Iñaki Barba, entonces responsable del departamento de arquitectura de RDT. Cito algunas de las conclusiones de los ponentes que pueden, creo, tener interés para conocer la problemática de las obras en la zona.
Toni Cladera, Profesor en la UIB, reflexiona sobre la necesidad de mejorar el entendimiento entre ingenieros indios y arquitectos españoles, y también sobre el modelo de construcción con ladrillo empleado:
“After visiting the different worksites one realizes that RDT people are working very well. In general good materials are used […] One clear exception is the brick. These bricks are made in open ovens, reaching temperatures of only around 350ºC, instead of 1200ºC or more that would be necessary for the ceramic material. This produces weak bricks with a low compression and tensile strength that will affect the durability of the building.
The first step to solve this problem is, in my opinion, to build in such way that the concrete structure and the brick walls are independent”
Carlos García Acón estudia los problemas generados por el esquema de vigas, pilares y losas de la estructura de hormigón:
“Concrete frame with rigid jointed beams and columns are the best solution to avoid problems with lateral loads coming from flood, different settlements or earthquake […] However, I think we can profit the employed solution […] the current solution presents a too heavy, and it has the defect of employing additional brick walls as a bearing element. This is the cause of […] cracks all over the windows and doors and in the joints of concrete and brick.
Furthermore, it is usual to find small buildings with footing settlements in different levels, looking for a ground with a good bearing capacity. Our suggestion is to use the plinth beam as a tie beam, connecting all the footings at the same level, improving the soil under the footing if necessary”
