Abstract
The Cross-Laminated Timber (CLT) concrete composite floor can successfully address the issues of conventional wood product and become an attractive alternative material for conventional reinforced concrete floors in mid to high-rise building. The purpose of this research was to fully evaluate the capacity of this novel hybrid composite material under both dynamic and static conditions, before such this hybrid system becomes widely employed. This was achieved by performing a full-scale testing of five floor specimens. One specimen was designed according to Eurocode 5 to satisfy the design load for common office buildings, and four specimens were prepared with a concrete topping with different connector types, connector angles, and connector spacing. The test results illustrated that the CLT–concrete floor specimens had excellent structural performance in terms of strength capacity, 3 –5 times higher than the conventional CLT floor. The vibration performances of this composite floors were also enhanced, resulting in a remarkably effective use of this innovative materials.
