| Abstract |
The purpose of this study was to evaluate the flexural performance of CLT-concrete composite floors that used steel shear connectors for
applying a light modular system. The proposed steel shear connectors are inverted U-shaped and T-shaped, and were installed in the notches
of the CLT floor. As experimental variables, the shear connector types, the number and thickness of CLT layers were considered, and the
flexural performance of six composite floor specimens was evaluated. As a result, the maximum loads of all specimens were determined by
rolling shear fractures and the specimens using the inverted U-shaped shear connector showed excellent flexural performance. However, the
composite effect between CLT and concrete was found to be insignificant, and it is considered that it is necessary to improve the shape of
steel shear connector later. |
