Descripción
Sumario:[EN] Mainly, to economize the construction process of building structures and slabs using successive levels of shoring, two strategies are adopted. On the one hand, it tries to reduce the time spent in each of the construction operations. On the other hand, it attempts to recover most of the components used as soon as possible. So these components can be used on the construction of upper floors. Through these two strategies, more efficient buildings construction processes are achieved. To achieve the desired efficiency, it is necessary to have a calculation method to evaluate different options. Thus, in this work it has gotten a software application which calculates and verifies building construction processes through the new simplified procedure by Calderon et al (2011) and other verified hypotheses. This software is able to consider the three construction system types available (Shoring/Striking, Shoring/Reshoring/Striking and Shoring/Clearing/Striking) for slabs, waffle slabs and girderless hollow floor slabs. It also takes into account the different possible boundary conditions. In addition, software application is able to consider different values of the number of successive levels of shoring, from a plant to four successive levels. The second objective of this work was to obtain optimal building construction processes. Different solutions were established from the different variables that form a building construction process. All options define the solutions field. From here, it can be choose full assessment of the solutions field or evaluate only a part through heuristic optimization. It has been shown that in very few cases is feasible to apply full assessment of the solutions field (only up to 3-storey buildings). Thus, in this work it has been developed different heuristic optimization strategies implemented in the software application. Three strategies are tested in order to minimise the economic cost: Random Walk (RW), First Best Gradient (FB) and Simulated Annealing (SA). After applying different strategies to a real case, it has been obtained that the most efficient strategy is simulated annealing (SA), which proceed to the most intelligent search of the optimal solution in this work. This strategy has achieved cost savings about 68 % of the shoring system material cost respect to the real process associated with the building construction taken into account in the second part of this work
