Development of Steel Plate-bolt Joint System for CLT Hybrid Structures: Structural Performance Evaluation and Component-level Experiment
Journal article, 2024

In this paper, a bolt-type steel joint system for CLT-steel hybrid buildings is proposed. The proposed connection consists of insertion steel plates and steel bolts with a large diameter that connect two CLT walls to steel beams. Evaluation methods to predict the structural performance of the connection are proposed and validated with component-level one-bolt connection tests. It was found that the methods can be used to predict the structural performance of the connection with good accuracy. The proposed connection can utilize the high strength and stiffness of CLT wall panels while maintaining an acceptable level of ductility.
