Assessment of the dynamic temperature profile in fire loaded sandwich structures based on wood in comparison with conventional structural systems

Assessment of the dynamic temperature profile in fire loaded sandwich structures based on wood in comparison with conventional structural systems

Paper in proceedings (conference paper)

Fire safety is an important feature of healthy internal environment. If a fire breaks out, the interior of fire compartments within the building is exposed to very high temperatures and further phenomena accompanying the burning process. All of them impact the boundaries of the compartment structures, including the structures that are located inside them. Some structures serve the load bearing function hand in hand with fire barriers, some are only fire barriers. As to the dramatic increase of temperature, its impact upon the opposite surface of the fire separating structure should be considered, in particular regarding the behaviour of the load bearing elements and their stability. This is topical at the present day, since the conventional construction materials are seen to give way to wooden sandwich structures that are preferred especially for their thermal insulation properties, low weight, small thickness and speediness of construction. The article uses dynamic simulation to illustrate how these modern structures react to high temperatures within specific time intervals, offering comparisons with traditional brick structures.
