Chen, B.Q., Garbatov, Y. e Guedes Soares, C. (2010), “Displacement Measurement of the Box Girder Based on Photogrammetry”, Proceedings of the 11th International Symposium on Practical Design of Ships and Other Floating Structures (PRADS 2010), Rio de Janeiro, Brasil, pp. 1053-1061
The objective of this work is to generate a threedimensional model of the initial and post test displacement measurements of a box girder. Photogrammetry, which employs a three-dimensional measurement technique and central projection imaging as a fundamental mathematical model, is used to generate the displacement field, from a set of digital photos. A three dimensional displacement model of a box girder before and after an ultimate strength test is performed using appropriate software. The results achieved are very successful as have been proved and can be used as input data to a finite element analysis of the ultimate strength of the box girder subjected to bending moment.
