Design of long-span building floors has been governed by vibration serviceability criteria, and cross-laminated timber (CLT) floors are no exception. High stiffness to mass ratio makes them highly susceptible to excessive vibrations induced by pedestrians walking, which is by no surprise the most frequent load case scenario in buildings occupied by people. Typically composed of multiple prefabricated CLT panels assembled on a building site, CLT floors have been an increasingly popular greener and build faster alternative to the traditional concrete and composite floors. This paper presents an experimental and preliminary numerical research designed to study potential benefits of reinforcing CLT panels with fiberglass reinforced polymer (FRP) bars on vibration performance of the floor assembly.

摘要

Design of long-span building floors has been governed by vibration serviceability criteria, and cross-laminated timber (CLT) floors are no exception. High stiffness to mass ratio makes them highly susceptible to excessive vibrations induced by pedestrians walking, which is by no surprise the most frequent load case scenario in buildings occupied by people. Typically composed of multiple prefabricated CLT panels assembled on a building site, CLT floors have been an increasingly popular greener and build faster alternative to the traditional concrete and composite floors. This paper presents an experimental and preliminary numerical research designed to study potential benefits of reinforcing CLT panels with fiberglass reinforced polymer (FRP) bars on vibration performance of the floor assembly.
