Abstract

Abstract: This paper presents a summary of experimental results from various studies conducted these twenty last years on the behaviour of steel-to-timber or timber-to-timber connections with dowel-type fasteners exposed to fire. The majority of the tested connections are loaded in tension parallel-to-grain and some of them loaded in tension at 45°, 90° and bending. The geometrical configurations of the tested connections are detailed and commented to facilitate further use. The tests in normal conditions are realized in order to obtain the real ultimate loads of the tested connections used as a basis to define the mechanical load in fire tests. Based on the fire resistance times of the tested connections, the experimental results are compared with those given by the design rules of EN 1995-1-2. The experimental results are presented in such a way that they can be used to validate numerical investigations that can be developed in order to understand the complex thermo-mechanical behaviour of timber connections. Thus, the paper provides to the researchers a database, of the main experimental results available in the world, related to the fire resistance of dowelled and bolted timber connection exposed to ISO fire.
