A New Method for Modelling Temperature Within Steel Bar - Timber Composite Beam Using Data by Burning Test

Abstract

In light of the current climate crisis, there has been much recent interest in using timber structural members in large buildings, since timber is as renewable natural resource, and moreover, in severe earthquake prone zones, such as Japan, they are more desired on the grounds of light weight of timber members. We are developing a frame system formed by hybrid timber members reinforced with deformed steel bars (i.e. rebars) using epoxy resin adhesive. In order to practice the system, it is necessary to investigate fire resistance performance of the members. We conducted a 60minute burning test of one specimen of the composite beam. The results will be reported in this WCTE2023[1]. This paper proposes a method for modelling temperature within beam specimen by using finite data obtained by the burning test.
