Thermal and mechanical evaluation of three types of wood subjected to different environmental conditions

Abstract EN

Wood is one of the most important natural materials for structural elements used in the building industry.

This paper deals with the thermal and mechanical behavior of different types of wood subjected to different environmental conditions.

Three types of wood were studied for their thermal and mechanical properties (Mahogany, Pitch Pine and Mosque).

Mass loss with time at different temperatures, water absorption and density for each type of wood were studied.

Also, bending and compressive strength in the parallel and perpendicular directions of the fibers were measured.

Specimens from each type of wood were subjected to direct fire at nearly 600oC for different exposure time.

These samples were repaired by GFRP wrapping systems.

The results show that clear differences in both thermal and mechanical properties of these types of wood were observed.

GFRP wrapping systems proved to be an effective method in repairing and strengthening wood structures subjected to fire.
