Abstract
ABSTRACTHybrid simulation is an economical structural testing technique in which the critical part of the structure expected to respond in the inelastic range is tested physically whereas the rest of the structure is modelled numerically using a finite element analysis program. This paper describes the application of hybrid simulation for steel I‐shaped columns in Multi‐Tiered Braced Frame (MT‐BFs) structures. A full‐scale W250×101 column part of a two‐tiered concentrically braced frame was physically tested while the rest of the frame was numerically analysed using the OpenSees finite element program. The development and main challenges of the hybrid simulation are first described and the main findings of the hybrid simulation are then presented. The test results show that the testing technique is an effective experimental tool to generate reliable data on column stability limit states. Furthermore, the results from the hybrid simulation confirmed the findings of previous numerical simulations to assess the seismic response of columns in steel braced frames.
