Cyclic Load Tests and Numerical Analysis of CLT Shear Walls With Gir Joints

Abstract

Four CLT shear wall specimens with GIR joints were subject to cyclic loading. The tensile anchor preyielding type specimens exhibited great performance and non-slip response because the M24 ABR steel anchors connected to the GIR joints contributed to resisting in compression. A numerical model using OpenSees was developed to simulate the global response and confirm the energy absorption. A crack was confirmed in one of the specimens before the GIR exhibited its ultimate strength. It is presumed that edge clearance distance may affect CLT shear walls performance for large deformations. The analysis model results are in good agreement with the experimental testing. Finally, the energy absorbed by the tensile bars on the compression side have been quantified.
