Abstract

Determination of construction displacements and deformations are an important parameter in assessing the condition and safety of the construction in its exploitation. Also, we get confirmation whether a structure is consistent with project solutions. Constant development of surveying instruments enables us to deal with more complex and demanding tasks that are facing engineering geodesy. Surveying instruments can measure, not only static and very slow displacements of the constructions, but also and faster (dynamic) displacements. In order to determine the accuracy, limitation and possibilities of surveying instruments, dynamic displacements of the constructions were simulated at the testing field. Surveying instruments were measuring simulated dynamic displacements with predefined frequency (up to 7.5 Hz) and amplitude of oscillation. Achieved results from the testing field, as well as results of the measurements from the roof construction of sports hall "Arena Zagreb" are presented in the paper.
