The influence of flexible sound insulation layers on the seismic performance of cross laminated timber walls

This paper presents the results of an experimental campaign investigating seismic behaviour full-size cross laminated timber (CLT) wall systems with sound-insulated shear-tension angle brackets. The main aim study was to investigate influence more and less flexible soundproofing bedding under CLT wall. shows a comparison lateral load-bearing capacity, displacement ductility stiffness obtained from racking tests on uninsulated specimens various types insulation levels vertical load. Moreover, analytical procedure estimate load-displacement response walls is proposed. model verified by direct experimentally determined backbone curves. show that elastomeric does not have significant effect bearing capacity system tested, but it reduces increases capacity. Due large decrease in stiffness, causes overall reduction ductility. estimation proposed able capture adequately predict
