Dissipate and Recentre

The dataset gathers all the information relative to the Dissipate and Recentre (D&R) project, including data and metadata.The project aimed at experimentally investigating the sway behaviour of large-scale GFRP frames. The objectives of the project were to assess the behaviour of these structures under lateral loading, assessing and proposing seismic design methods and guidelines. The experimental campaign was performed at the European Laboratory for Structural Assessment (ELSA) of the JRC, and the User Access Team comprises well-established senior experts, several young researchers and an industrial partner (SME). The members of the proposing team have a leading role in ongoing efforts for the development of European standards for the design of FRP structures, for which the results of the project can provide essential knowledge. Such standards will support the market uptake of this innovative technology in the construction sector.The test specimens consisted of 2-storey frames, with 2 longitudinal bays and a single transverse bay. The structures were made of pultruded GFRP profiles, with stainless-steel connections. Concrete precast slabs were installed on the GFRP beams creating the floors of the specimens, simulating the equivalent vertical loads on of a real application, and allowing to anchor the actuators. The experimental campaign included the testing of four specimens: two without lateral bracings and two with such bracings. The modal identification of all specimens was performed using data of snap-back tests. For both types of frames, the first specimen was tested under monotonic loading, while the second underwent cyclic pseudo-static loading with increasing displacement amplitude. All tests were performed under displacement control. During the tests, the monitoring system recorded the applied loads and displacements, as well as rotations and strains of joints and members at key locations.
