The application of virtual reality technology in the construction of bridge: The cantilever and incremental launching methods

摘要

Virtual reality technology was applied to the development of two models related to the activity of bridge construction. One model presents the cantilever method of bridge deck construction and the other model concerns the incremental launching method of bridge deck construction, both frequently used construction techniques. The developed interactive applications make it possible to show the physical evolution of the construction work, the monitoring of the planned construction sequence, and the visualization of details of the form of every component of each construction. They also support the study of the type and method of operation of the equipment necessary for these construction methodologies. Specialists in construction processes and bridge design were consulted and involved in the development of the educational models in order to obtain efficient, accurate didactic applications. The pedagogic considerations and the technical knowledge transmitted by the models are evident in the selection of the quantity and type of elements to show in each virtual model, and in the choices made regarding the sequence in which those elements are shown as well as in the relationship established between the components of both types of construction. The developed models bring new perspectives to teaching as a support when discussing new curricular issues or complex sequence construction, both students and teachers interacting with the VR models.
