Three case studies about research projects carried out at BAM were presented. All three projects focussed on the survey of parameters and safety related tasks in bridge engineering and inspection. First, the monitoring of the Berlin main station was presented with focus on the sensors developed specifically for this project. The second case study presented and application of guided ultrasonic waves to CFRP-strengthened bridges. The method was sucsessully applied to two of four different strengthening measures carried out min. 10 years ago. The last project presented the feasibility study of a network consisting of simple Bluetooth modules to survey changes in the moisture content in sand and massive concrete. 2018 Workshop University of New South Wales, Sydney, Australia 17.07.2018 17.07.2018 2018-08-07 OPUS4-46872 Vortrag Helmerich, Rosemarie Feasibility study about monitoring moisture inside massive concrete Current measurement methods for dertermination of moisture analyse near-surface moisture distribution. During an externally funded research project, microwaves in the Bluetooth(R) frequency band width were utilized for Setting-up a module network. Without additional sensors, the feasibility study confirmed that threedimensional data can collected to obtain a threedimensional data set as basis for the estimation of moisture distribution inside massive building materials. 2018 2nd International Conference on Ultrahigh Performance Concrete, UHPC2018 Fuzhou, China 07.11.2018 10.11.2018 2018-12-04
