Investigation of Timber Members at the Marasyk Station in Prague by Non-Destructive Methods

Abstract:

The Masaryk Railway Station is the oldest still working terminal railway station in Europe. It was built in 1845 and the buildings belonged to the most splendid railway stations in that time. During the long life the part of Masaryk Station burned, it was also damaged while World Wars and finally large reconstruction started last year. The buildings have a high historical value, so the specialists from National Heritage Institute wanted all the original structural members to be preserved. The structure was constructed from two wooden species spruce and fir. Selected timber elements were tested by various non-destructive methods to assess their health. Pilodyn, a device with iron stick can assess a material quality using correlation between depth of stick indentation and material strength. Sylvatest device operates with ultrasonic waves and can determine dynamic modulus of elasticity as one of the mechanical characteristics. Dynamoe device uses an acoustic wave to assess the material quality. The aim of the paper is to present the procedure of timber testing and to discuss measured results.
