Resumen

This project contents the seismic vulnerability evaluation of the antique cathedral building of municipality of Ambalema in the Department of Tolima. With the seismic vulnerability evaluation has been set to check the stability of the structure under gravitational loads and the proper recommendations for structural reinforcement if required, in purpose to guarantee structural stability and its preservation, given such as importance that this structure represents for the cultural patrimony of the region and the country. The project is divided in the phases: the first one is about documentation and loads evaluation of the structure. Initially an investigation of the clinic history of the building was made, the uses that the structure has had along its use life, modifications, changes and improvements that have taken place over it, events that have affected it, and other aspects. Parallel to this, architectonic and topographic surveys were made in order to make digital plans that allowed to make a first graphic registration of the architectonic and structural characteristics of the building. This first phase also cover the measuring of the mechanical characteristics both linear and non-linear of the materials that compose the building, those of adobe, interphase mortar and wood. Laboratory tests, field measurements (sclerometry, nucleus samples). From laboratory results and those taken measurements the team expects to obtain specific weights of the pieces and constructive materials, as well as compression resistance, flexo-traction, module of elasticity, module of fracture and fracture criteria, which are being developed in the investigation. Second and third phases are out of the reach of this document, however the panning has been enunciated. In the second part of the project a lecture of the result is principally going to be made, as well as the registration and qualification of the information and the development of calculation models and its validation. It’s planned to make a modeling of finite elements and rigid elements of the structures, which will end up on relevant information respecting the actions over them, stresses acting on them and failing mechanisms or collapse. The third phase of the interdisciplinary work is about the recommendations for structural reinforcement and the restoration of the architectonic elements that may be affected.
