Load testing of new Bridges with wireles sistem of equpement

Bridges are construction objects that are an integral part of almost every road. Theirdamage often results in the collapse of the transport system and particularly affects traffic safety. To avoid such a thing, it is necessary to carry out certain checks before putting the bridges into traffic, which will provide information in advance about whether there is a possibility of future damage. One of them is the so-called test load for new bridge before it is taken into service. Therefore, bridge testing is the last external monitoring action to be performed when a new bridge is built. The objective of these tests is to verify that the mechanical behavior of the loaded structure conforms to its design model. The system evaluated as part of this study was the Bridge Diagnostics, Inc. (BDI) Wireless Structural Testing System (STS-Wi-Fi). All results are compared with theoretic values based on the FE-model of the bridge and are calculated using software SOFISTIK AG. Both the experimental results as well as the and analytical results are presented in this paper and compared. The comparison of the analytical results showed good agreement with the experimental results.
