DESCRIPTION:This presentation examines the structural response\, disassemb
 ly\, and reuse potential of steel-timber shear connections. It includes re
 sults from experiments and numerical simulations under various loading con
 ditions. A detailed account of the complete deformation response and the m
 ain mechanical parameters of the tested shear connections for conventional
  and slim steel-timber floors is presented. Non-linear finite element simu
 lations were carried out to validate the main numerical parameters for ste
 el\, timber\, and interaction characteristics\, and then used for parametr
 ic investigations. Based on the results and observations\, code-modified e
 xpressions for evaluating stiffness and load resistance were proposed with
 in the ranges considered and validated against a collated database. A cons
 titutive model was developed to predict the full load-slip response of she
 ar connections\, which can be adopted for discrete non-linear modelling of
  connectors. A reuse potential testing protocol was developed to evaluate 
 performance after cyclic loading and reassembly\, and a modified separatio
 n damage index was introduced to quantify the circularity of these systems
 . A sensitivity study for the tested shear connections and other practical
  configurations for steel-timber floors was also carried out for evaluatin
 g the circularity of such systems.
