The implementation of a new friction tension-only “GripNGrab” device attached to rocking steel frame is described. device, when subject significant tension dissipates energy via sliding in the frictional component. When loaded compression direction, almost no compressive force carried, but displacement occurs ratchetting This absence any within dissipative system means that will always recentre...

The environment is one of the factors that may influence occupants’ perception floor vibration and assessment serviceability. In this study, laboratory tests were conducted on a 3-ply CLT floor. Occupants’ serviceability under human-induced was investigated. Virtual reality (VR) technique used as research method, simulating two common environments in life. First, correlation between annoyance r...
