TL;DR
This paper presents experimental data on large-scale GFRP composite frame structures tested under lateral loading to assess their structural integrity and seismic performance.
Contribution
The paper provides a detailed dataset and observations from full-scale tests on GFRP composite frames under monotonic and cyclic loading.
Findings
GFRP frames maintained structural integrity up to 2% inter-storey drifts with minimal damage.
Both braced and unbraced configurations showed similar performance under lateral loading.
The results suggest GFRP frames can be designed to withstand significant seismic actions.
Abstract
In the scope of the Dissipate&Recentre project, which was granted access to the ELSA Reaction Wall of the Joint Research Centre physical research infrastructure of the European Commission, large scale composite frame structures were tested under lateral loading. The test specimens, comprising pultruded glass fibre reinforced polymer (GFRP) profiles, connected with stainless steel elements, had two longitudinal (test direction) bays, two storeys and a shorter transverse bay. Concrete slabs were provided as flooring system, simulating a quasi-permanent load level – as that used in seismic design. A total of 4 full-scale specimens were tested, two including a bracing system, also comprising pultruded GFRP profiles, and two without bracings. For each configuration, one specimen was tested under monotonic loading and the other under cyclic loading. The aim of this paper is to disseminate the…
