Abstract: Geometric imperfections in thin-shell structures such as silos and tanks need to be measured to assess the buckling strength of the structures, and to develop new structure design criteria. A number of difficulties are ...

Abstract: A surface-profile measurement system is introduced, with emphasis on the design and the measuring principles of the system. Originally developed for the measurement of imperfections in large-scale steel silos, the system ...

Abstract: In this study global positioning system (GPS) technology is used to monitor the structural movement of a cable-stayed bridge over the River Tamar in northern Tasmania, Australia. Observed displacements are compared with ...
