Geotechnical seismic isolation technology with rubber-soil trenches for earthquake resilience of existing structures (ERIES-GSIRST)

This dataset contains acceleration and velocity recordings of the EuroProteas structure (foundation and roof) and the soil in the vicinity of the structure, under forced vibration tests, and diffraction of wave propagation from the source to the structure using a trench filled with gravel-rubber mixtures. The aim of ERIES-GSIRST experimental program was to demonstrate the feasibility of using trench fills with Rubber–Soil mixtures (RSm) to reduce incoming ground vibrations. Trench fills are a well-known and widely used vibration-isolation system that aims to attenuate energy by scattering, intercepting, and diffracting surface waves, as reported in the literature. For this purpose, a trench approximately 5.5 m long and 0.40 m wide was constructed at a distance of about 2 m from the foundation slab of the structure. The trench depth reached 1.80 m. Different RSm configurations were tested as trench fills in order to evaluate the effectiveness of these mixtures for vibration isolation. The configurations that were tested were 100% rubber (per volume), 75% rubber per volume, and 50% rubber per volume (and the rest gravel). All field tests were conducted at the Euroseistest/EuroProteas facility. Drawings, instrumentation layout, and photos are also included in the dataset. This work is part of the transnational access project “ERIES-GSIRST”, supported by the Engineering Research Infrastructures for European Synergies (ERIES) project (www.eries.eu), which has received funding from the European Union’s Horizon Europe Framework Programme under Grant Agreement No. 101058684.
