Seismic performance of a 3D full‐scale high‐ductility steel–concrete composite moment‐resisting structure—Part I: Design and testing procedure

Abstract

SUMMARYA multi-level pseudo-dynamic (PSD) seismic test programme was performed on a full-scale three-bay twostorey steel-concrete composite moment-resisting frame built with partially encased composite columns and partial-strength connections. The system was designed to provide strength and ductility for earthquake resistance with energy dissipation located in ductile components of beam-to-column joints including flexural yielding of beam end-plates and shear yielding of the column web panel zone. In addition, the response of the frame depending on the column base yielding was analysed. Firstly, the design of the test structure is presented in the paper, with particular emphasis on the ductile detailing of beam-to-column joints. Details of the construction of the test structure and the test set-up are also given. The paper then provides a description of the non-linear static and dynamic analytical studies that were carried out to preliminary assess the seismic performance of the test structure and establish a comprehensive multi-level PSD seismic test programme. The resulting test protocol included the application of a spectrum-compatible earthquake ground motion scaled to four different peak ground acceleration levels to reproduce an elastic response as well as serviceability, ultimate, and collapse limit state conditions, respectively. Severe damage to the building was finally induced by a cyclic test with stepwise increasing displacement amplitudes.

Damage identification of a 3D full scale steel–concrete composite structure with partial‐strength joints at different pseudo‐dynamic load levels

“…The slabs were reinforced with transversal rebars in order to activate strut and tie mechanisms between slabs and columns [2,4]. Braconi et al [5,6] gave a complete description of the structure, including the design methods and structural performance data.…”

“…The testing programme included a sequence of PsD tests, simulating earthquakes with peak ground acceleration (PGA) scaled up to the collapse onset limit state (COLS), followed by a final cyclic test. The MR structure behaved well under seismic loading and details of the seismic design and performance can be found in [5,6].…”

“…Both studies were successful in joint identification, although only simple beam-to-column joint models in the elastic range were considered. Chellini et al [16] used modal identification in order to perform damage detection of semi-rigid partial-strength joints experiencing severe inelastic damage in the composite structure analysed in [5,6] and characterized by low masses, low damping and complex geometry. However, the overall understanding of damage 1221 evaluation in these structures and the issues related to the application of model updating techniques, remains largely unexplored and are the topics of this paper.…”
