Simulation of a bridge deck construction using precast beams supported in Virtual Reality technology

In the execution of bridge decks or viaducts, several construction methods are adopted. In this Thesis the construction methods most frequently applied in bridge decks using precast beams are presented. For the considered work a 4D (3D + time) geometric model was implemented in a virtual reality environment, which simulates the construction of a deck, allowing the visualization and interaction with the several steps and key elements intervening in this process. For the conception of the virtual model, an analysis of the construction components, steps inherent to the process and his sequence as well as the type e and operation mode of the required equipment was performed. Based on that analysis, a 3D geometric modeling of the different elements that characterize the construction place was performed and a coding sequence was established that could allow simulating the construction activity in an interactive way. The model is interactive, allowing the user to have access to the different phases of the constructive process, thus obtaining distinct visualizations both in time and space through the lifetime of the construction, improving that way the understanding of this constructive method. The model has a didactic character and may be used as a support in the formation of students and professionals in the study area of Bridges.
