6. DEHUMIDIFICATION SYSTEM 7. SHMS (Structural Health Monitoring System)
Corrosion of cable wires and structural steel elements
are main factors adversely affecting condition of the
steel bridges. Cable dehumidification is now an
established and effective method for old and new
bridge main cables. In the US, Japan, Denmark, UK
and recently in Turkey the main cables of many
suspension bridges are equipped with cable
dehumidification system. The Structural Health Monitoring System is an integral
part of the structure of Osmangazi Bridge. Osmangazi
Bridge is heavily instrumented with various devices for
monitoring the structural behavior (such as vehicular
weight, wind speed, seismic, other environmental
and structural parameters) and effects on the bridge
(such as strains, acceleration, displacement,
temperature).
The cable anchorage chambers, internal deck box
sections, the inside of the towers and the main cables
of Osmangazi Bridge are designed and equipped with
the latest dehumidification systems. The data from those sensors and equipment are
transferred to the Bridge Control Center through the
SCADA system and displayed,
recorded and
processed to make assessment and optimize the
required maintenance.
