Evaluation of Cable Forces in the Roof Structure at RCP Amazon Court

摘要

The paper presents the results of an experiment carried out on the cables of the roof structure of the RCP Amazon Court. The tensile forces in the roof cables were determined using vibration frequency method (VFM). The VFM is often used in practice because it provides an efficient, cheap and relatively easy way to determine the cable forces and a standard measuring line for dynamic experiments can be used. The paper also discusses the task of the result accuracy of the used methods. The results of the described experiment show that production tolerances and mounting method can significantly influence the stresses in statically indeterminate load bearing structure with cables. Therefore, it is important to verify forces in cables experimentally in these structures during their construction and it is also suitable to monitor cable forces during their service life.
