A low-damage steel structure using resilient slip friction joint for a full-scale shaking table test (2020)
The objective of this study is to present the design and numerical analysis for some structural applications of Resilient Slip Friction Joint (RSFJ) as low-damage structural systems in a steel structure for shaking table tests. These structural applications include tension-only and tension/compression braced frames as well as moment resisting frame (MRF). During seismic events deformation compatibility and members interaction, members and connection in- and out-ofplane behavior, and dynamic loading are of concern. Following this research, the design of the mentioned RSFJ structural systems will be illustrated. A full-scale three-dimensional three-story steel structure is designed using the equivalent static method. The structure is assumed to be located in Wellington, New Zealand on a soil class C with an importance level of two including two bays in the longitudinal direction and one bay in the transverse direction and total planar dimensions of 7.25 by 4.75 m and the inter-story height of 3 m. Then, the RSFJs are designed in different applications using nonlinear push-over analysis including joints nonlinearity. Then, nonlinear time-history analysis (NLTHA) is undertaken to check the members and the RSFJs adequacy. One record is selected which acceptably matches the site target spectrum over the period range of interest and is scaled to serviceability limit state (SLS). The test is to happen at the International Joint Research Laboratory of Earthquake Engineering (ILEE), Shanghai, China. According to the design undertaken, a resilient structure is proposed with no need to replace any structural component which in turn can meet immediate occupancy requirements.
