Abstract

A prototype hybrid Timber-FRP Glulam beam is being investigated for developing a floor timber system with an enhanced performance during and after fire. In this research study, analytical investigation has been conducted to simulate the flexural capacity of the prototype. The Glulam beams were fabricated with a single lamella being reinforced using Carbon Fibre Reinforced Polymer (CFRP) fabric. The CFRP was wrapped around and adhered to the second lamella from the bottom, with the first lamella serving as a sacrificial layer of timber that could protect the FRP for some duration. The increase in fire performance of the reinforced beams has been investigated through experimental and theoretical modelling approaches. The analytical model presented in this paper relies on the first principles of elastic-plastic stress-strain distributions. Results show the model capability to predict the flexural behaviour of this type of hybrid Glulam beams at ambient condition and after heating due to a range of fire scenarios.
