Once a structure has reached its service life or does not satisfy the requirements or capacity it was designed to withstand, it may be possible to resort on rehabilitation. If that were not to be the case, the replacement or removal of the structure becomes a necessity. Demolition is a common technique in construction used to liberate a space or alternate the use of it, commonly associated with cities due to the limited space in them.
The aim of this thesis is to propose an analysis method for the demolition of structures related to bridges. This paper contains a study and comparison for a variety of available techniques and their application in a case study for an optimal methodology procedure in the demolition of a pedestrian bridge project in Maspalomas, Gran Canaria. Finally, a conclusion of the guidelines to follow with the criteria applied is presented.
This paper will discuss the most relevant factors for a correct criteria in the selection of demolition methods for bridge structures. Different operative procedures will be presented and compared, and therefore a comprehensive study of these factors which affect the final decisions; budget, time consumption, safety, environmental impact and the effect of the traffic disruption. The main methodologies presented will be variables of mechanical demolitions. Other methodologies, as the use of explosives, chemical demolition methods or manual demolition activities will be contemplated and compared.
By the end of this paper, the applications of different methodologies will offer a visual example of different possibilities to approach a demolition project. The case study presented in section 3, which will result in a preliminary design project for the Spanish local authorities, as in Ayuntamiento de San Bartolomé de Tirajana, is intended to be executed. This case study may serve as a guideline for any similar demolition at the same project phase. A conclusion will be presented from the theoretical study of different methodologies and from the results in the comparison of their practical application.
