GREENERGY HYBRID WORKSHOP on
Resilient Vertical Forest Renovation of Reinforced Concrete Structures in Seismic-Prone Areas
Organized under the research project GREENERGY
The 3D structure is fully instrumented with internal strain gauges on the steel bar surfaces and embedded smart aggregates with PZT sensors. Further, externally bonded PZT patches, attached accelerometers, displacement wire-meters and externally bonded strain gauges are utilized. Two types of tests have been performed, i.e. dynamic shake table tests and tests for determination of dynamic characteristics of the as-built structure. The dynamic shake table tests comprised of gradually increasing maximum input intensity level (peak acceleration of the excitation) from 0,1g to 1,1g based on the adopted earthquake of Thessaloniki 1978. Τhe next video is for 1,1g.
GREENERGY aims to investigate Reinforced Concrete Structure in Seismic Prone Areas after Resilient Vertical Forest Renovation. This phase focuses on the retrofitting process of the columns and brick infills of the test specimen, along with the modifications and additions made to receive Vertical Forest (VF) renovations. The VF structure was tested on the seismic table at the Democritus University of Thrace (DUTh) as part of a comprehensive experimental program consisting of 28 seismic tests. Among these, the EQ0.14g excitation (top video) represented a low-intensity seismic event, while the EQ1.40g excitation (bottom video) corresponded to the maximum shaking level. The lower excitation produced minor vibrations with limited response, whereas the 1.40g test caused severe dynamic motion, clearly demonstrating the structure’s deformation behavior and damage progression under extreme seismic demands.
