Shaking table tests of a 3-storey self-centring steel MRF: preliminary analysis and design
Traditional seismic design methods, suggested by current codes and conventionally applied worldwide, rely on damage to building structures to dissipate the seismic input energy. This strategy allows meeting the life safety requirements but often results in post-earthquake scenarios where building structures are severely damaged with significant direct and indirect losses strongly affecting the overall resilience of communities. To address this issue, nowadays’ earthquake engineering is facing an extraordinarily challenging era to provide more widely affordable, high-seismic-performance structures capable of sustaining the design earthquake intensity with limited socio-economic losses. To this end, the ERIES-SC-RESTEEL (i.e., SelfCentring seismic-RESilient sTEEL structures) project investigates the structural response, repairability, resilience, and performance recovery of steel low-damage self-centring moment-resisting frames, including friction devices and post-tensioned bars with disk springs at column bases and beam-to-column joints. A wide range of shaking table tests will be carried out at LNEC (Laboratório Nacional de Engenharia Civil) in Lisbon, Portugal, investigating the performance of a large-scale 3D three-storey steel moment-resisting frame with low-damage self-centring joints considering different properties and placements of the self-centring connections. As part of the ERIES-SC-RESTEEL project, this paper presents the preliminary numerical work for the design of the experimental tests. Advanced numerical models of the test specimen have been developed in OpenSees to perform non-linear time history analyses considering various design configurations, ground motion records and seismic intensities. The results provide useful insights for the design of shaking table tests and the expected experimental outcomes.
