Because vibration measurements Schönausteg.
Beginning next Monday, 26 October 2009, carries out the civil engineering department of the city of Berne on Schönausteg vibration measurements. The Schönausteg is therefore up to and including Wednesday, 28 October 2009, each closed during the day.
A private seismologist who runs the seismographic station of Bern, has made the public works office to point out that the Schönausteg in dynamic oscillations (triggered by internal and joggers joggers) to swing to a greater degree begins. Because of the unusual results, the Civil Engineering Department has decided to investigate the behavior of the Schönausteg both static and in dynamic oscillations.
For this purpose have been developed in collaboration with external specialists bridge, a measuring method which can simulate the vibration behavior of the bridge. Specifically, should be determined how the Schönausteg in the case of static loads (people standing on the bridge) or (joggers cross the bridge) for dynamic loading behavior.
be a result of the test results, statements about the serviceability and the structural safety of Schönausteg . Make In particular, can judge if necessary to built in 1906, Aare-transition reinforcement measures. To get a complete picture of the state of the bridge will be reviewed simultaneously with its steel construction.
work on three days spread
for the tests and measurements probably three working days are required. From Monday 26 October 2009 to Wednesday, 28 October 2009, the Schönausteg are therefore locked in each case from 08.00 bis 17.00 clock. He is not the day for pedestrians therefore impassable. Moreover
is scheduled to a later date on Altenbergsteg Vibration measurements. The date for this work is still not fixed.
