Development of Lattice - Shaped CLT Shear Walls

Key Points

The aim is to develop a shear wall system using lattice-shaped CLTs and assess its buckling restraint performance.
Developed shear wall with steel rods and pipes in a lattice grid structure
Implemented glued-in-rod joint system between steel pipes and CLTs
Conducted element experiments in compression
Performed one-unit and 2×3-unit horizontal load tests
Demonstrated effective buckling restraint performance of the shear wall system
Highlighted stability improvements under horizontal loads
Validated performance through multiple testing configurations

Abstract

Authors have developed a shear wall consisting of steel rods restrained from buckling with steel pipes and CLTs are placed in a lattice grid within the building framework. Glued-in-rod (GIR) joint system is adopted for joining between the steel pipes and CLTs. The buckling restraint performance of this system was investigated through element experiments in compression, one-unit horizontal load tests and 2×3-unit horizontal load tests.
