Mechanical performance of connection components of irregular nodes in prefabricated shear walls
The node connector of prefabricated shear wall is a key technology to ensure the overall performance of the structure.In order to fully understand its stress characteristics in prefabricated shear walls,monotonic tensile,monotonic compressive,and low-cycle reversed load tests were conducted on different forms of node connectors.The results show that the compressive performance of the T-shaped plate rigid connector is relative-ly weak.Under monotonic tensile and low-cycle reversed load actions,significant flange buckling phenomena of the T-shaped plate and composite rigid connectors are observed,with large overall deformation and damage lev-els,but the energy dissipation capacity is improved.The overall deformation and damage levels of the butt plate and composite rigid connectors are reduced,but the crushing force between the bolt and the hole wall increases significantly,leading to a significant decrease in overall energy dissipation capacity.
